Product Details
This kit includes 2 components, each built and powder-coated in-house.
Eliminate Caster Issues Regain Full Front-End Control
Take control of your Jeep Wrangler JL's suspension with the Cruise Series Front Control Arm Set, engineered to correct alignment, re-center the front axle, and restore proper caster angle. From the factory, caster angles are often insufficient, leading to wandering, instability, and tracking ruts in the road. When lifting your JL, these deficiencies become even more pronounced.
This complete Front Upper and Lower Control Arm Set fully corrects those issues, delivering improved handling, steering precision, and superior off-road flexibility.
Key Features Benefits
- Corrects Caster Angle for Stability – Restores proper caster geometry on lifts from 0 to 6 inches, eliminating wandering and rut tracking.
- Re-Centers the Axle – Ensures the front axle remains properly aligned in the wheel well for optimal suspension performance.
- Heavy-Duty Steel Construction – Built from strong steel tubing for superior strength and durability over factory parts.
- Tapered Polyurethane Bushings – Provides enhanced responsiveness, reduced road noise, and improved ride quality.
- Recommended Pairing – For a complete front-end suspension solution and reduced risk of death wobble, pair with the Cruise Series Front Track Bar (CRS-J-JL-FTB1).
Precision Engineering for Maximum Control
The Front Lower Control Arms are responsible for correcting caster and centering the axle, while the Front Upper Control Arms provide fine-tuned alignment adjustments.
When combined, this kit fully restores stability and driveability, making your JL handle better both on-road and off-road.
Two-Stage Powder Coating for Maximum Durability
Each control arm is finished with a premium two-stage powder coating process: Zinc Primer Base Coat – Ensures superior corrosion resistance and long-term durability. Durable Top Coat – Available in 10 custom colors to match your Jeep’s build.
Proudly Made in the USA
Designed and manufactured in Orem, UT, this kit is a testament to high-quality American craftsmanship. By sourcing raw materials locally and overseeing the entire production process, we guarantee exceptional durability and performance.
