4. Operating and Adjustment
The Bonrath Coil-over Kit allows for adjustable ride height on the front axle. This adjustment should only be performed when the vehicle is safely supported and the suspension is unloaded.
Ride Height Adjustment:

- Once the desired height is achieved, securely tighten the locking collars.
- After adjustment, it is recommended to drive the vehicle a short distance and then re-check the ride height. A wheel alignment may be necessary after significant height changes.

Recommended Maintenance Schedule:
- Every 10,000 km or 6 months: Inspect all suspension components for signs of wear, damage, or corrosion. Check for loose bolts and retorque if necessary.
- Annually: Clean the coil-over threads and apply a thin layer of anti-seize grease to prevent seizing, especially in areas exposed to road salt or harsh weather.
