Optimized Rear Suspension Control
Upgrade your Jeep Wrangler TJ or LJ (1997-2006) with the Cruise Series Rear Upper Control Arms, designed to correct pinion angle, recenter the rear axle, and eliminate driveline vibrations. These control arms provide greater strength and adjustability over stock components, making them a must-have upgrade for lifted Jeeps looking to improve handling and drivetrain longevity.
Key Features and Benefits
- Pinion Angle Correction – Properly adjusts pinion angle to eliminate driveline vibrations and reduce wear on drivetrain components.
- Rear Axle Recentering – Ensures accurate axle alignment to maintain stability and handling after lifting your Jeep.
- Heavy-Duty Construction – Built from heavy-duty steel tubing for unmatched durability in on- and off-road conditions.
- Polyurethane Bushings – Provides superior responsiveness, vibration absorption, and longevity over standard rubber bushings.
- Recommended Pairing – For complete rear-end suspension alignment and axle centering, pair with our Cruise Series Rear Lower Control Arms (CRS-J-TJLJ-RL2).
Precision Adjustability
Our fully adjustable Rear Upper Control Arms are engineered to fine-tune pinion angle and re-align the rear axle. With a range supporting 0 to 6 inches of lift, they provide crucial adjustments to optimize handling and drivetrain function. If your lift exceeds 6 inches, contact us for additional options.
Two-Stage Powder Coating
For maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 customizable colors for a long-lasting, stylish finish.
Made in the USA
Proudly manufactured in Orem, UT, our Cruise Series components support American craftsmanship and are built to the highest performance and durability standards.
Optional Hardware Upgrade
Installation is straightforward using factory hardware, but for those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately for a seamless installation process.
