| 1 | Confirm the exact vehicle application | Check vehicle make, model, model year, market, body style, engine or powertrain, and drivetrain. Fitment can differ between versions of the same model. | Provide the vehicle identification number (VIN) or the full vehicle details, then confirm the application against a reliable parts catalogue or supplier fitment record. |
| 2 | Match the axle and installation position | Verify front or rear position, left or right where applicable, and whether the part is intended for a specific axle configuration. Front and rear units are not automatically interchangeable. | Check the position shown in the vehicle parts information and on the product documentation before ordering quantities for a complete vehicle. |
| 3 | Verify mounting style and dimensions | Compare the upper and lower mounting types, including eye, pin, stem, clevis, or other application-specific designs. Check bushing, sleeve, bolt-hole, and mounting-width dimensions. | Use a dimensioned drawing or measure the original unit and mounting points. Confirm that fasteners and bushings suit the vehicle; do not rely on appearance alone. |
| 4 | Check extended and compressed lengths | Compare the shock absorber's extended length, compressed length, and resulting stroke with the application requirements. Measurement reference points must be consistent, usually mounting center to mounting center. | Request the supplier's measurement method and dimensional drawing. Confirm that the unit will not bottom out at full compression or exceed its safe travel at full extension. |
| 5 | Confirm suspension and ride-height configuration | Check whether the vehicle has standard, heavy-duty, sport, off-road, self-levelling, or factory-lowered suspension. Aftermarket lift or lowering changes can affect required travel and compatibility. | State any suspension modifications, ride-height changes, or special equipment when requesting a fitment check. Confirm that the shock is approved for that configuration. |
| 6 | Choose the appropriate construction | Identify whether the application calls for a twin-tube or monotube design and whether it requires a gas-charged or other specified construction. Design alone does not establish vehicle compatibility. | Match the proposed construction to the vehicle requirements and intended use. Ask for the product specification sheet rather than assuming one design is suitable for every vehicle. |
| 7 | Review damping and load requirements | Check the specified damping characteristics, operating conditions, and intended vehicle load. A shock absorber controls suspension movement; it should not be treated as a substitute for a load-rated spring. | Describe normal and maximum operating loads, road conditions, and usage. Confirm the supplier's recommended application and do not infer performance from dimensions alone. |
| 8 | Compare part references and supersessions | Cross-check the original equipment reference, replacement reference, and any documented superseded numbers. A number match should still be checked against vehicle position and application details. | Request written confirmation of cross-reference and application coverage. Keep the reference list with the purchase order so the delivered part can be checked on receipt. |
| 9 | Check materials, protection, and operating limits | Review rod and body protection, seals, corrosion protection, fluid or temperature operating limits where specified, and any environmental or durability requirements relevant to the destination market. | Ask for published technical data and applicable test or compliance documentation. Check that packaging and corrosion protection are suitable for the shipping route and storage conditions. |
| 10 | Confirm inspection, warranty, and shipment details | Confirm product identification, production traceability, inspection criteria, warranty terms, packaging quantity, and the documentation supplied with the shipment. | Agree on acceptance criteria and required documents before ordering. On arrival, inspect part numbers, mounting details, visible condition, and quantities before installation. |
