- Attach the lower mount to the vehicle's control arm or knuckle.
- Reconnect any disconnected components (sway bar links, brake lines, etc.). Ensure all bolts are tightened to the manufacturer's specified torque.
- Initial Ride Height Setting: Before fully tightening all bolts, set an approximate ride height. Refer to the 'Operating and Adjustment' section for details on adjusting ride height.
- Perhimpunan Akhir: Reinstall the wheels and lower the vehicle. Torque the lug nuts to specification.
- Selepas Pemasangan: Drive the vehicle for a short distance to allow the suspension to settle. Re-check all fasteners for tightness. A professional wheel alignment is mandatory after coilover installation.

5. Pengendalian dan Pelarasan
Your maXpeedingrods coilovers allow for ride height adjustment. The damping value is preset for consistent performance.
5.1 Pelarasan Ketinggian Tunggangan
The ride height can be adjusted by twisting the lower mount on the threaded shock body. This allows for a lowering range of 1-3 inches from the original ride height.
- Loosen the lower mount (A) and locking ring (B) using the provided adjustment wrenches.
- Rotate the lower mount (A) to increase or decrease the threaded distance, thereby changing the ride height. Rotating clockwise will lower the vehicle, and counter-clockwise will raise it.
- Once the desired height is achieved, tighten the lower mount (A) and locking ring (B) securely against each other to prevent movement.
- Repeat for all four coilovers, ensuring even height on both sides of the vehicle.

5.2 Pelarasan Pramuat
The preload on the spring can be adjusted using the locking ring (C) above the spring perch. This adjustment should only be performed by experienced individuals or professionals, as incorrect preload can affect ride quality and handling. The factory preset is generally suitable for most applications.
