Regain Control Stability
Eliminate wandering, improve drivability, and regain proper caster angle with the Cruise Series Front Lower Control Arms. Designed specifically for the Jeep Wrangler JL (2018-Present), these control arms address the factory caster deficiency that can lead to wandering, instability, and following ruts in the road—especially after lifting your vehicle. Built for durability and performance, this upgrade provides enhanced on-road handling and superior off-road flexibility.
Key Features Benefits
- Corrects caster for improved stability – Restores proper caster angle, eliminating wandering and rut tracking.
- Heavy-duty steel construction – Provides unmatched strength and durability over factory control arms.
- Tapered polyurethane bushings – Reduces road noise and enhances responsiveness for a smoother ride.
- Fully adjustable for lifted vehicles – Accommodates lifts up to 6 inches, ensuring precise alignment correction and axle re-centering.
- Recommended pairing – For lifts above 3 inches, pair with Cruise Series Front Upper Control Arms (CRS-J-JL-FU2) for full caster control and complete front-end suspension tuning.
Built for Strength Performance
Unlike factory control arms that struggle to maintain alignment after a lift, the Cruise Series Front Lower Control Arms are designed to restore proper suspension geometry. By correcting caster angle, they dramatically improve steering feel, reduce driveline vibrations, and prevent instability.
Two-Stage Powder Coating for Maximum Durability
Every control arm undergoes a rigorous two-stage powder coating process: Zinc primer base coat – Creates a corrosion-resistant foundation for long-term durability. Durable top coat – Available in 10 custom colors for added protection and personalization.
Proudly Made in the USA
Designed and manufactured in Orem, UT, these control arms reflect the highest quality of American craftsmanship. By sourcing materials locally and overseeing the entire production process, we ensure superior durability and performance.
