Regain Proper Caster Improve Front-End Stability
When lifting your Jeep Wrangler JL, maintaining proper caster angle is crucial for steering stability, handling, and overall drivability. Factory suspension geometry is already lacking in caster, and adding a lift can worsen the issue—leading to wandering, following ruts in the road, and a loose steering feel.
Our Cruise Series Front Upper Control Arms are designed to fine-tune caster correction, improving steering precision, high-speed stability, and tire wear. When paired with our Cruise Series Front Lower Control Arms (CRS-J-JL-FL2), this combination completely restores axle centering, suspension alignment, and caster angles, offering a full front-end suspension solution for lifted Jeeps.
Key Features Benefits
- Restores proper caster angle – Adjustability allows fine-tuning of suspension geometry, eliminating wandering, pulling, and unstable steering after lifting your Jeep.
- Improves steering response high-speed stability – Proper caster helps keep your steering wheel centered and reduces fatigue from constant corrections.
- Heavy-duty steel construction – Built from high-strength steel tubing, these arms deliver long-lasting durability and enhanced off-road performance.
- Unique U-bracket design – The axle end U-bracket mounts directly to the factory axle bushing, maintaining a secure and quiet ride.
- Recommended pairing for maximum stability – Combine with our Cruise Series Front Lower Control Arms (CRS-J-JL-FL2) to fully correct caster, re-center the axle, and eliminate steering instability.
Adjustability for Lifts from 0 to 6 Inches

If you’re running a lift over 3 inches, pairing with our adjustable Front Lower Control Arms ensures full caster correction and axle re-centering for maximum control. For lifts beyond 6 inches, contact us for additional options.
