Frequently Asked Questions (FAQ)

1) Which truck suspension kits are best for mixed European duty cycles (motorway + jobsite)?

• For 7.5–18t rigs doing dual duty, pair reinforced multi-leaf springs at the rear with serviceable monotube shocks and progressive bump stops. Add air-assist for height levelling on variable loads.

2) How do I spec kits for cold climates versus Mediterranean regions?

• Cold/Nordics: low-temp damper fluid, HNBR/FKM seals, ≥720h ASTM B117 hardware, anodised/aluminium bodies. South EU: higher-temp fluid, dust boots, and corrosion coatings for coastal salt air.

3) What documentation should B2B buyers request before bulk PO?

• IATF 16949/ISO 9001, TÜV/CE/ECE evidence where applicable, shock dyno plots (hot/cold), material/heat-treatment certs, salt-spray results, torque specs, and VIN/axle-load fitment guides.

4) How do lift/geometry changes affect EU compliance and fleet insurance?

• Lifts >50 mm often require additional checks (headlamp aim, ESP calibration, brake line length). Verify local approvals (e.g., TÜV/ABE or national inspections) and notify insurers to avoid coverage issues.

5) What maintenance intervals reduce downtime on fleet trucks?

• Visual checks every 10–15k km; torque verification after first 500–1,000 km post-install; damper/bushing inspection each service; rebuildable dampers: service 60–80k km under mixed duty, sooner for off-road.

2025 Industry Trends

• Shift to serviceable monotube dampers in medium-duty fleets to cut lifecycle cost.
• Growth of air-hybrid kits (leaf + air) for urban logistics and e-commerce last-mile trucks.
• Data-led stocking: distributors use VIN-level demand plus telematics wear indices.
• Corrosion resistance becomes a buying criterion: zinc-nickel fasteners, e-coat brackets standardising at ≥720h B117.
• Private-label Truck Suspension Kits expand via EU e-commerce and regional warehouses in CEE.
