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.
