Optimize Pinion Angle and Maximize Drivetrain Efficiency
Upgrade your Toyota 4Runner’s rear suspension with the Cruise Series Rear Upper Control Arms, engineered for precise axle positioning, improved handling, and drivetrain vibration reduction. Designed for model years 2003-2024, these fully adjustable control arms allow for proper pinion angle correction, reducing driveline vibrations while optimizing rear suspension performance.
Key Features and Benefits
- Precision Pinion Angle Adjustment – Corrects driveline geometry, reducing driveline vibrations and optimizing rear axle alignment.
- Full Axle Control When Paired with Rear Lower Control Arms – Combine with Cruise Series Rear Lower Control Arms (CRS-T-4R-03-RL2) for complete control over axle positioning, ensuring proper articulation and alignment.
- Adjustability for a Perfect Fit – Designed for 0 to 6-inch lifts, allowing for axle recentering and optimized suspension geometry.
- Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) for a smoother ride and longer-lasting durability.
- Heavy-Duty Construction – Fabricated from robust steel tubing, ensuring maximum strength and off-road durability.
Pinion Angle Correction for Reduced Driveline Vibrations
Lifting your vehicle alters the rear pinion angle, often leading to increased driveline vibrations and excessive wear on the U-joints. The Cruise Series Rear Upper Control Arms allow precise pinion angle adjustments, minimizing unwanted vibration and ensuring optimal drivetrain efficiency.
Two-Stage Powder Coating for Maximum Durability
Each Cruise Series Rear Upper Control Arm undergoes a two-stage powder coating process for superior corrosion resistance and long-term durability: Zinc primer base coat – Provides maximum rust protection. Durable top coat – Available in 10 color options, allowing for added customization and style.
Proudly Made in the USA
The Cruise Series Rear Upper Control Arms are manufactured in Orem, UT, using high-quality domestic materials. Our commitment to precision craftsmanship ensures reliable performance and unmatched durability.
Upgrade your 4Runner’s suspension today for a smoother, more controlled, and off-road-ready driving experience!
