Performance and Control
Enhance your Jeep Gladiator JT’s performance on and off the road with our Cruise Series Rear Upper Control Arms. Designed for 2020-Present models, these control arms provide superior strength, precise adjustability, and durability over factory components, making them a critical upgrade for lifted vehicles.
Key Features and Benefits
- Pinion Angle Correction – Adjustable design eliminates driveline vibrations by properly aligning the rear pinion angle.
- Axle Re-centering – Works in conjunction with rear lower control arms to maintain optimal axle position.
- Heavy-Duty Steel Construction – Built to withstand extreme off-road conditions while improving handling.
- Tapered Polyurethane Bushings – Enhances ride quality by reducing vibrations and providing superior responsiveness.
- Recommended Pairing – For a complete rear-end alignment solution, pair with our Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2).
Precision Pinion Angle Alignment
One of the most overlooked but critical factors in suspension geometry is pinion angle alignment. When lifting a Jeep Gladiator, the pinion angle often becomes misaligned, leading to driveline vibrations, premature wear, and reduced drivetrain efficiency. Our adjustable Rear Upper Control Arms allow you to precisely correct the pinion angle, ensuring smooth operation and extending the life of drivetrain components.
When combined with our Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2), this setup gives you full control over axle alignment and pinion correction, minimizing suspension stress and improving overall handling.
Two-Stage Powder Coating
Our control arms undergo a two-stage powder coating process for maximum durability and corrosion resistance. Zinc primer base coat – Provides superior rust protection. Durable top coat – Available in 10 color options, letting you customize your control arms to match your build.
Made in the USA
Proudly manufactured in Orem, UT, our Cruise Series Rear Upper Control Arms are built using locally sourced materials and strict quality control standards to ensure unmatched durability and performance.
Optional Hardware Upgrade
These control arms can be installed using factory hardware. However, if you're dealing with rusted or seized bolts, we offer Grade 8 hardware kits separately to streamline installation and ensure a secure fit.
