Optimized for Alignment and Caster Correction
Lifting your Jeep changes its suspension geometry, which can lead to misalignment, poor handling, and increased suspension wear. Our adjustable Front Upper Control Arms allow you to:
- Fine-tune caster angle for improved steering feel and high-speed stability.
- Correct pinion angle to reduce driveline vibrations, especially after installing a lift.
- Re-center the axle when paired with our Cruise Series Front Lower Control Arms (CRS-J-JK-FL2), ensuring proper suspension geometry and enhanced drivability.
For lifts above 3 inches, pairing Front Uppers with Front Lowers is highly recommended to achieve full caster control and optimal axle positioning.
Two-Stage Powder Coating for Maximum Protection
Each Cruise Series Front Upper Control Arm undergoes a two-stage powder coating process to ensure maximum corrosion resistance and long-lasting durability. Zinc primer base coat prevents rust and protects against harsh conditions. Durable top coat available in 10 custom colors for added protection and customization.
Effortless Installation
Our Cruise Series Front Upper Control Arms are designed for quick and straightforward installation using factory hardware. If replacement bolts are needed, we offer optional Grade 8 hardware kits separately for a hassle-free setup.
Proudly Made in the USA
Manufactured in Orem, UT, the Cruise Series Front Upper Control Arms reflect the highest standards of American craftsmanship. By choosing CORE 4X4, you're investing in high-quality, American-made suspension components built for durability and superior performance.
