4. الإعداد والتثبيت
This section provides general guidelines. Always consult your vehicle's specific service manual for detailed removal and installation procedures of the original suspension components.
- تحضير: Park the vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the wheels. Jack up the vehicle and secure it with jack stands. Remove the wheels.
- إزالة نظام التعليق الأصلي: Carefully remove the original shock absorbers and springs according to your vehicle's service manual. This typically involves disconnecting sway bar links, brake lines (if necessary), and unbolting the top mount and lower mount.
- تركيب نظام التعليق الجديد:
- Install the new maXpeedingrods coilover assemblies. Ensure the top mount bolts align correctly with the vehicle's chassis mounting points.
- 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.
- التجميع النهائي: Reinstall the wheels and lower the vehicle. Torque the lug nuts to specification.
- بعد التثبيت: 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. التشغيل والضبط
Your maXpeedingrods coilovers allow for ride height adjustment. The damping value is preset for consistent performance.
5.1 Ride Height Adjustment
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 ضبط التحميل المسبق
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.

6. الصيانة
Regular maintenance ensures the longevity and optimal performance of your coilovers.
- التفتيش الدوري: Periodically inspect all coilover components for signs of wear, damage, or corrosion. Check for leaks around the shock body.
- نظافة: Keep the coilover threads and shock bodies clean from dirt, salt, and debris. A full-length dust boot is provided to protect the piston shafts.
- فحوصات المثبتات: Regularly check the tightness of all mounting bolts, locking rings, and top mount nuts. Re-torque to specifications if necessary.
- تنسيق: After any significant ride height adjustment, or if uneven tire wear is observed, have a professional wheel alignment performed.
