View Component →Maximize Caster Control and Front-End Stability
Upgrade your Jeep Wrangler JK (2007-2018) with the Cruise Series Front Control Arm Set, designed to restore proper caster angles, improve axle centering, and enhance overall drivability. Whether you're addressing factory alignment deficiencies or correcting geometry changes from a lift, this set provides the optimal balance of strength, adjustability, and control for both on-road stability and off-road articulation.
Key Features and Benefits
- Regain Caster Improve Steering Control – Factory suspension geometry and small lifts reduce caster angle, leading to wandering steering and instability. This set corrects caster and re-centers the front axle, ensuring a more stable, controlled ride.
- Heavy-Duty Steel Construction – Built to outlast and outperform factory control arms, these arms offer superior impact resistance and long-term durability.
- Tapered Polyurethane Bushings for Responsiveness – Designed for improved articulation, vibration dampening, and better road feel, compared to standard rubber bushings.
- Full Adjustability for Lifted Vehicles – Ideal for suspension lifts from 0 to 6 inches, restoring proper axle position and caster alignment to maintain smooth handling and reduced driveline vibrations. For lifts beyond 6 inches, contact us for additional solutions.
- Complete Suspension Solution – For full control over axle positioning, pinion angles, and suspension geometry, pair this set with our Cruise Series Rear Control Arm Set (CRS-J-JK-RS4). Together, they provide a comprehensive upgrade for improved handling, stability, and long-term durability.
Two-Stage Powder Coating for Maximum Protection
Every Cruise Series Front Control Arm undergoes a two-stage powder coating process for maximum durability and corrosion resistance: Zinc primer base coat prevents rust and enhances longevity. Durable top coat available in 10 custom colors for added style and resilience.
Effortless Installation
The Cruise Series Front Control Arm Set is designed for quick and easy installation using factory hardware. For vehicles with rusted or seized bolts, we offer optional Grade 8 hardware kits separately to simplify the installation process.
