OWEN SPRINGS Car Parts
Owen Springs is a British specialist in leaf-spring manufacture. The AutoMotoPart range reflects that focus closely: complete spring packs form the core selection, while centre bolts, spring-eye bushes and U-bolts provide associated repair hardware. These parts appear straightforward, but a spring is defined by more than vehicle name. Axle position, rated application, leaf arrangement, width, length, eye or slipper design and mounting dimensions all influence the correct reference.
Begin with the exact vehicle or trailer configuration, VIN or chassis information and the axle being repaired. Establish wheelbase, gross or axle-weight specification, suspension option and any conversion that changes the original load arrangement. The current AutoMotoPart selection contains 122 Owen Springs items, led by 82 spring pack entries, 20 central bolt entries, 13 leaf spring bush entries, 4 u-bolt entries. These Owen Springs figures describe the range on this page rather than every product the brand may make elsewhere.
Compare a known-correct spring only when it is unloaded and safe to measure. Record leaf count, leaf width and thickness, centre-bolt position, eye-to-eye or eye-to-end dimensions and bush sizes. Camber on a worn or broken pack is not a reliable identification dimension. U-bolts must match rod diameter, shape, leg length and thread, while centre bolts must locate the pack correctly without being treated as a general clamping substitute.
Leaf springs store substantial energy. Support the chassis and axle independently, use equipment suitable for the vehicle's weight and follow current repair information before loosening U-bolts or shackles. Do not weld, heat, drill, straighten or mix leaves to improvise a match. Renew specified locking hardware, tighten in the required sequence and recheck ride height, axle location, hose and cable clearance after the vehicle is settled. Keep the spring reference and measured configuration with the repair record until the suspension has been settled and inspected under normal vehicle loading. The Owen Springs products below are a reference-led selection; final suitability depends on the complete specification and the vehicle in front of you.

Owen Springs: understand the range before choosing
Owen Springs describes itself as a British leaf-spring manufacturer with an accredited manufacturing facility and a range serving light commercial vehicles and other sectors. That specialism matches the products on this page: complete spring packs dominate, supported by centre bolts, leaf-spring bushes, U-bolts and a small number of other spring entries. The page therefore concentrates on identification, stored energy and correct chassis installation.
AutoMotoPart currently lists 122 Owen Springs items. The largest Owen Springs groups are 82 spring pack entries, 20 central bolt entries, 13 leaf spring bush entries, 4 u-bolt entries. Owen Springs totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Owen Springs listing, its current technical information and the item in front of you must agree.
What the Owen Springs page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Spring Pack | 82 | Confirm axle, side where applicable, leaf count, width, length, centre location and rated vehicle configuration. |
| Central Bolt | 20 | Use the specified centre-bolt diameter, length, head form and thread; it locates the pack as well as holding leaves during assembly. |
| LEAF SPRING BUSH | 13 | Match spring-eye or shackle position, inside/outside diameter, width and material arrangement. |
| U-BOLT | 4 | Confirm round or square form, rod diameter, inside width, leg length, thread and axle-seat shape. |
| LEAF SPRING | 2 | Treat a complete leaf spring by its full application and dimensional record, not approximate camber. |
| U BOLT | 1 | Treat a complete leaf spring by its full application and dimensional record, not approximate camber. |
The current selection contains 82 spring packs, 20 centre bolts, 13 leaf-spring bushes and five U-bolt entries under slightly different product wording. That balance matters: a complete pack and a small locating fastener do very different jobs, and neither should be ordered from a shared brand name alone. Retain the Owen Springs reference through dismantling so removed hardware can be compared without mixing positions.
Build a reliable shortlist
Leaf-spring selection combines application and geometry. Vehicle data identifies the intended load and axle arrangement; measurements distinguish nearby designs; inspection reveals whether surrounding hangers, shackles or seats are also responsible for the fault. Use unloaded dimensions only where the current Owen Springs or vehicle information calls for them.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Vehicle and axle | Front, rear, driven, tag or trailer axles can use different packs | VIN/chassis data, axle identification and current application record |
| Load configuration | Heavy-duty, camper, tipper or conversion variants may change spring specification | Plate data and documented suspension option, not payload guesswork |
| Spring geometry | Length, width, leaf count and centre position control location | Published dimensions plus an unloaded known-correct pack |
| End arrangement | Eyes, slippers, shackles and bushes create different interfaces | Mounting drawing and physical hanger arrangement |
| U-bolt form | Rod size, bend shape and leg length must suit axle and seat | Exact Owen Springs dimensions and undamaged mating parts |
| Paired condition | Unequal packs can alter ride height and axle attitude | Inspect both sides and follow the vehicle replacement policy |
A broken leaf can obscure the original shape, and a sagged pack can make camber comparison misleading. If identification depends on the damaged part alone, obtain further chassis or application evidence. Never add an extra leaf or substitute a heavier pack without engineering information confirming the altered suspension and load behaviour.
Complete spring packs and how they share load
A multi-leaf pack carries vertical load while helping locate the axle. Leaves slide slightly against one another as the pack flexes, and clamps keep them aligned without replacing the function of the centre bolt or axle U-bolts. Owen Springs references can therefore differ in leaf count, graduated lengths and end design even where two vehicles share a basic chassis family.
Inspect for a fully fractured leaf, a leaf shifted sideways, polished impact marks, broken rebound clips and contact with bump stops. Surface corrosion needs interpretation, but deep section loss near the centre, eyes or leaf ends deserves careful assessment. A vehicle leaning to one side may also have uneven loading, a damaged hanger, seized shackle, tyre issue or body conversion, so measure on level ground after obvious loads are accounted for.
Centre bolts are locating components
The spring-pack centre bolt passes through aligned leaf holes and locates the assembled pack in relation to the axle seat. Its head often engages a matching hole. An Owen Springs centre-bolt choice therefore needs the correct shank, head, length and thread, not merely enough length to pass through the leaves. A loose generic bolt can allow movement and damage the seat.
Pack assembly and centre-bolt replacement involve stored energy. Leaves must be aligned and compressed with suitable equipment before the old bolt is released; the bolt itself must not be used to draw a widely separated pack together. Follow the approved sequence and reject leaves with elongated centre holes, cracks or damage created by previous movement.
Bushes, eyes, shackles and hanger movement
Leaf-spring bushes allow controlled movement at spring eyes or shackles while isolating metal contact. Owen Springs bush selection should include inside diameter, outside diameter, overall width and the exact mounting position. A dimensionally similar bush can still have a different sleeve or flange arrangement, and forcing it can split an eye or leave the inner sleeve unsupported.
Check shackle plates, pins and chassis hangers for wear or corrosion before pressing in a new bush. Final tightening position matters where a bonded rubber bush must sit without twist at normal ride height. Grease only where the design and instructions require it; lubricant that attacks rubber or defeats an interference fit can turn a correct bush into an early failure.
U-bolts, axle seats and tightening sequence
U-bolts clamp the axle, spring and seat as a system. Their bend profile must sit correctly around the axle or saddle, while rod diameter and thread determine the specified nut and tightening data. Owen Springs U-bolts with similar leg lengths are not interchangeable if the inside width or bend shape differs. Re-bending a hardened or formed U-bolt is not a valid fitment method.
Clean seating faces and inspect locating holes before assembly. Use new U-bolts and nuts where the vehicle procedure specifies them, bring the fasteners down evenly and apply the stated staged or cross sequence. Recheck requirements after the suspension has settled if the instructions call for it. Unequal tightening can distort a seat, shift the centre location or leave clamp load inconsistent across the axle.
Safe removal, ride height and completion checks
Position the vehicle on a stable level surface, support the chassis at approved points and support the axle separately before dismantling. Brake hoses, ABS wiring, load-sensing links and parking-brake cables may span the moving axle, so prevent them carrying weight. Spring eyes and shackle bolts can release suddenly when load paths change; keep hands and body clear of the expected movement.
After fitting Owen Springs parts, settle the suspension as directed and compare ride height on level ground. Confirm axle location, tyre-to-body clearance, bump-stop space and the routing of every disturbed hose or cable. Steering-wheel position on vehicles with a driven or steered leaf-sprung axle can also reveal axle alignment issues. Any pull, new vibration, clamp movement or abnormal noise needs investigation before continued use.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Diagnose | Confirm the failed leaf, bush, fastener or mounting and assess both sides | Ordering a spring from vehicle lean alone |
| Identify | Record chassis, axle, load option, Owen Springs reference and dimensions | Measuring only the camber of a sagged pack |
| Support | Hold chassis and axle independently with correctly rated equipment | Allowing a hose, cable or spring bolt to carry axle weight |
| Assemble | Use specified new hardware, alignment and tightening sequence | Drawing leaves together using the centre bolt |
| Verify | Settle suspension, check ride height, axle location and clearances | Returning to service before movement or clamp load is checked |
Keep the Owen Springs reference, measured configuration and tightening record with the job. If ride height or axle position remains unequal, revisit loading, hanger condition, spring identity and seat location rather than assuming every new pack will mask an underlying chassis problem.
Reading real Owen Springs references
The Owen Springs names below are examples from the current range and show why the complete description matters. They are not universal Owen Springs recommendations and should not be treated as a fitment list. Within Owen Springs, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Owen Springs BU436 LEAF SPRING BUSH | Axle, load variant, leaf count and spring dimensions |
| Owen Springs BU447 LEAF SPRING BUSH | Bolt diameter, length, head and pack thickness |
| Owen Springs BU466 LEAF SPRING | Bush position, bore, outside diameter and width |
| Owen Springs BU602 LEAF SPRING BUSH | U-bolt form, inside width, leg length and thread |
| Owen Springs BU605 LEAF SPRING BUSH | Axle, load variant, leaf count and spring dimensions |
| Owen Springs BU607 LEAF SPRING BUSH | Bolt diameter, length, head and pack thickness |
| Owen Springs BU609 LEAF SPRING BUSH | Bush position, bore, outside diameter and width |
| Owen Springs BU638 LEAF SPRING BUSH | U-bolt form, inside width, leg length and thread |
Example Owen Springs names often repeat ‘spring pack’ or ‘centre bolt’, so the full reference and measurements carry the useful distinction. Treat each title as an index into the specification rather than a complete installation instruction.
Common errors around Owen Springs products
- Choosing an Owen Springs pack from wheelbase and model while ignoring axle or load option.
- Using worn camber as the main identification measurement.
- Mixing individual leaves from unrelated packs to alter ride height.
- Using the centre bolt to pull an uncontrolled spring pack together.
- Re-bending or re-threading a U-bolt to fit a different axle seat.
- Tightening bonded bushes in the wrong suspension position.
- Failing to protect brake hoses and wiring while the axle is supported separately.
- Overlooking hanger, shackle or seat damage after replacing the visible broken leaf.
Owen Springs questions and answers
Q: What dominates the Owen Springs range here?
A: Complete spring packs are the largest group, followed by centre bolts, bushes and several U-bolts.
Q: Can I identify a spring by leaf count?
A: Leaf count helps, but axle, load option, width, lengths, centre position and end arrangement must also agree.
Q: Is spring camber a reliable identification dimension?
A: Not on a worn or broken pack; use current dimensional and application information.
Q: Can I add a leaf to increase carrying capacity?
A: Not without approved engineering information, because the change affects suspension and load behaviour.
Q: May I reuse leaf-spring U-bolts?
A: Follow the exact repair procedure; many applications specify new U-bolts and nuts after release.
Q: Can a centre bolt compress the spring pack?
A: It locates and retains an already controlled pack; suitable clamps or equipment must manage spring force.
Q: Why does U-bolt bend shape matter?
A: The form must seat around the axle or saddle without point loading or forced re-bending.
Q: Should both spring packs be replaced together?
A: Inspect both sides and follow the vehicle policy, considering ride-height and condition differences.
Q: When are bonded bushes finally tightened?
A: Use the position specified by the vehicle procedure, often a defined normal ride position.
Q: What else should be inspected with a broken spring?
A: Check hangers, shackles, bushes, axle seats, clamps, bump stops, hoses, cables and the opposite pack.
Q: Is welding a cracked leaf acceptable?
A: No; use an approved replacement rather than welding, heating or straightening a safety-critical spring leaf.
Q: What should be checked after fitting?
A: Verify settled ride height, axle location, fastener security, tyre clearance and every disturbed hose or cable.
