Key Features Benefits
- Vehicle Fitment: Jeep Grand Cherokee WJ (1999-2004) – Corrects driveline angles and optimizes rear upper control arm geometry after a lift.
- Core Advantage – Raises the rear axle mounting point to improve suspension articulation, reducing stress on factory components.
- Adjustability – Designed for lifts between 2” and 4”. For lifts over 4”, we recommend our Adjustable A-Arm with Axle Bracket (CMP-J-WJ-AA1).
- Construction – Precision laser-cut from 1/4" steel plate, professionally welded for superior strength and durability.
Optimized Suspension Geometry
Installing a lift kit on your WJ can alter driveline and rear upper control arm angles, leading to poor suspension performance. This A-Arm Spacer raises the mounting point on the rear axle, restoring proper geometry to maintain stability, articulation, and overall drivability.
Two-Stage Powder Coating
Finished with our signature two-stage powder coating process, this spacer is built to resist corrosion and maintain a clean, professional appearance, even in harsh conditions.
Made in the USA
Proudly manufactured in Orem, Utah, this A-Arm Spacer meets the highest standards of craftsmanship, supporting American manufacturing and quality control.
Conclusion
The WJ A-Arm Spacer (J-WJ-AAS1) is an essential upgrade for Jeep Grand Cherokee WJ owners looking to improve handling, correct driveline angles, and enhance durability after a lift. Upgrade today and experience better suspension performance on and off the trail!
