Coilovers integrate shock absorber, adjustable spring and threaded sleeve into one full kit. Unlike factory single-function shocks or fixed lowering springs, they support independent ride height adjustment and multi-stage damping tuning. Stock springs only drop car height without handling improvement, while our coilovers balance stance, street comfort and corner stability for performance builds, pickups and 4WD off-road vehicles.

The shock body uses heavy-duty seamless steel with anti-corrosion coating; springs are high-tensile SAE9254 silicon manganese steel. Internal piston rods are hard chrome-plated, paired with imported oil-resistant sealing rings. They resist rust, oil leakage and fatigue under rough coastal, mountain and off-road driving conditions.

All kits come with full height adjustment via threaded sleeves. We offer single-adjustable (rebound only) and double-adjustable (compression + rebound) versions. Street daily drivers pick single-adjust for cost efficiency; track, towing and off-road customers choose double-adjust to fine-tune soft/hard stiffness for different road surfaces.

Most models are direct bolt-on fit with complete mounting brackets, rubber top mounts and spanner wrenches included in the kit. No cutting or chassis welding needed. We only recommend a professional wheel alignment after height adjustment to avoid uneven tire wear and steering pull.

Full fitment database covers Japanese/European sports cars, US pickup trucks, Australian 4WD SUVs, electric vehicles and large-displacement motorcycles. We keep updated fitment specs for new-year models to help shops avoid wrong-size returns and lost orders.

Yes, full OEM private label service is available. We laser engrave your brand logo on shock bodies and spring sleeves, plus customize color boxes and user manuals. Long-term bulk distributors get free fixture/mold fees with no extra hidden cost.

Absolutely. Coilovers can be loaded together with carbon ceramic rotors, brake pads, steel braided brake lines and forged alloy wheels in one FCL/LCL shipment, which greatly cuts overall sea freight cost for your one-stop tuning parts order.

Every batch passes salt spray, fatigue and high-speed dyno damping tests, with complete factory test reports. The documentation meets DOT and ADR entry standards to prevent customs detention for bulk wholesale shipments.

Standard in-stock models ship within 2–4 working days. Custom logo, spring rate or special lift height orders take 10–16 working days. Small trial sample orders are welcome for new distributors to test local market demand.

With proper cleaning and maintenance of threaded sleeves, our coilovers maintain stable performance for 50,000–100,000 miles. Signs of wear include oil leakage or abnormal bump noise; we provide spare seal kits for simple onsite maintenance to lower shop after-sales workload.

We supply free high-res installation photos, off-road/track test videos, fitment catalogs and product spec sheets. You can directly use these assets on social media, store display and website landing pages to boost local sales conversion.

We provide a 2-year factory warranty against manufacturing defects. Damage caused by improper installation, extreme off-road abuse or lack of maintenance is excluded. Our after-sales team offers fast technical troubleshooting via email and WhatsApp for global clients.
