常见问题
•What distinguishes gas-oil shocks from plain hydraulic in this catalogue?
Gas-oil (low-pressure gas-charged) absorbers resist foaming under sustained corrugated-road pounding and keep damping consistent on long rough stretches; plain hydraulic units cost less and ride softer at low speed. For markets with washboard gravel roads, gas-oil versions are usually worth the difference. Many references exist in both versions — the listing states which.
•Are reinforced springs available for permanently overloaded vehicles?
Yes — overload coil springs and additional-leaf packs are regular catalogue positions, not custom items, because the domestic market drives the same demand. State the real operating weight honestly, including typical cargo; the supplier picks a spring rate that carries it without breaking the geometry. Pairing reinforced springs with matching shocks avoids premature absorber failure.
•Should I stock rubber or polyurethane bushings for my market?
Both have a case. Rubber is quieter, cheaper and correct for customers who want original behavior; polyurethane lasts notably longer in heat and under load but transmits more vibration and costs more. Successful distributors typically stock rubber for volume and offer polyurethane as the premium line for taxis, pickups and fleet operators.
•How do I run a meaningful quality trial before committing to container volume?
Take samples of your three to five fastest-moving references and put them on working fleet vehicles — taxis or delivery vans accumulate distance quickly, so 90 days yields real data. Record installation dates and mileage. Factories here are accustomed to this procedure with export buyers and will often supply trial sets at a reduced rate.
•What MOQ and lead times are typical for suspension orders?
Fast-moving references ship from stock; factory production runs for larger volumes take two to four weeks. Minimums are modest — carton or pallet level per reference — but pricing steps meaningfully at consolidated container volume. A mixed 20-foot container of springs, shocks, joints and bushings is a realistic and economical first order for a regional distributor.
