View Component →Eliminate Factory Suspension Issues Regain Full Control
From the factory, Jeep Wrangler JL models suffer from insufficient caster, leading to unstable steering, wandering, and poor highway manners. Lifting the vehicle only amplifies these issues, causing even more caster deficiency, axle misalignment, and increased driveline vibrations. The Cruise Series Control Arms Set is the ultimate solution to these problems, providing full adjustability to restore proper suspension geometry, re-center both axles, and improve handling. Whether you're upgrading for off-road capability or improved daily driving performance, this all-in-one kit ensures your suspension is dialed in for optimal stability and responsiveness.
Key Features and Benefits
- Eliminates factory caster deficiency – Regain proper caster alignment for improved steering response, reduced wandering, and enhanced highway stability.
- Re-centers front rear axles – Fully adjustable to correct axle shift caused by lifting, ensuring proper suspension geometry and better drivability.
- Adjustable for lifts from 0 to 6 inches – Provides the flexibility to fine-tune suspension settings for different lift heights while preventing driveline vibrations and uneven tire wear.
- Heavy-duty steel tubing construction – Built for maximum durability, ensuring strength in off-road conditions while maintaining on-road comfort.
- Tapered polyurethane bushings for enhanced ride quality – Offers improved vibration dampening and responsiveness, outperforming traditional rubber bushings.
For lifts over 6 inches, contact us for custom solutions.
Recommended Pairing for a Complete Suspension Solution
For maximum stability and axle alignment, pair this kit with our Cruise Series Track Bar Kit (CRS-J-JL-TBK2), which includes front and rear adjustable track bars. Together, these components fully correct caster, steering geometry, and suspension alignment—eliminating issues like wandering, following ruts in the road, and death wobble.
Durable Two-Stage Powder Coating
Every control arm is powder-coated for long-lasting durability and corrosion resistance. A zinc primer base coat provides superior rust protection, while the durable top coat—available in 10 color options—adds extra durability and customization.
