Maximize Alignment and Suspension Performance
Upgrade your Jeep Wrangler JK (2007-2018) with the Cruise Series Front Upper Control Arms, engineered for increased strength, durability, and precise alignment control. Whether you’re tackling rugged trails or daily driving, these control arms provide the stability and adjustability needed to maintain proper suspension geometry and improve overall handling.
Key Features and Benefits
- Strength durability – Constructed from robust steel tubing, providing superior resilience over factory parts.
- Precise adjustability – Accommodates 0 to 6 inches of lift, helping restore alignment and drivability after suspension modifications.
- Unique U-bracket design – The axle end features a U-bracket, allowing easy installation onto the factory-mounted axle bushing.
- Tapered polyurethane bushings – At the adjusting end, these bushings provide enhanced stability, improved responsiveness, and reduced vibrations.
- Complete suspension solution – Pair with Cruise Series Front Lower Control Arms (CRS-J-JK-FL2) to fully recenter the front axle and correct caster for maximum handling performance.
Optimized for Alignment and Caster Correction
Lifting your Jeep changes its suspension geometry, which can lead to misalignment, poor handling, and increased suspension wear. Our adjustable Front Upper Control Arms allow you to:
- Fine-tune caster angle for improved steering feel and high-speed stability.
- Correct pinion angle to reduce driveline vibrations, especially after installing a lift.
- Re-center the axle when paired with our Cruise Series Front Lower Control Arms (CRS-J-JK-FL2), ensuring proper suspension geometry and enhanced drivability.
For lifts above 3 inches, pairing Front Uppers with Front Lowers is highly recommended to achieve full caster control and optimal axle positioning.
Two-Stage Powder Coating for Maximum Protection
Each Cruise Series Front Upper Control Arm undergoes a two-stage powder coating process to ensure maximum corrosion resistance and long-lasting durability. Zinc primer base coat prevents rust and protects against harsh conditions. Durable top coat available in 10 custom colors for added protection and customization.
Effortless Installation
Our Cruise Series Front Upper Control Arms are designed for quick and straightforward installation using factory hardware. If replacement bolts are needed, we offer optional Grade 8 hardware kits separately for a hassle-free setup.
