Product Description
Coil Spring 93188900
This component (OE 93188900 / 424112) is a rear coil spring. It is a key part of the rear suspension, supporting the vehicle's weight and absorbing road shocks. Over time, coil springs can sag or break, leading to a lower ride height, poor handling, and a harsh ride. Replacing this coil spring restores the vehicle's ride quality and load-carrying capacity.
Key Features
Direct OEM Replacement: Designed to replace the original coil spring, ensuring a perfect fit and restoring factory ride specifications.
Restores Ride Height: Replaces the worn or sagging spring to restore the vehicle's proper ride height.
Resolves Common Issues: Directly addresses common symptoms like a sagging rear end, bottoming out over bumps, and a rough ride.
High-Quality Construction: Manufactured from high-strength steel to meet strict quality standards, ensuring durability and long service life.
Corrosion Resistant: Features a corrosion-resistant coating to withstand harsh road conditions.

Installation and Usage Notes
-
Always replace rear springs in matching axle pairs. A new spring on one side and an old spring on the other can cause the vehicle to lean by as much as 20 mm, compromising rear axle alignment.
-
When removing the old spring, place a jack under the rear axle and lower it slowly after disconnecting the shock absorber lower bolt. Allow the axle to droop sufficiently to extract the spring without force.
-
Inspect the upper and lower spring perches for rust perforation or cracking. Damaged perches must be repaired or replaced-a new spring will not compensate for structural damage to its mounting surface.
-
Install the new spring with the identification stripe (orange) positioned on the upper side, oriented toward the outside of the vehicle. This ensures the spring's natural bow aligns with the axle's travel arc.
-
After installation, lower the vehicle to ride height and bounce the rear suspension several times to settle the spring before tightening the shock absorber mounting bolts to their final torque.
