Construction & Design

The control arms are built with heavy-duty steel tubing and feature a durable, black powder-coated finish that resists corrosion and rust. The Uniball joints are sealed with high-quality boots to prevent dirt and debris ingress, ensuring long service life. The design incorporates high-clearance geometry to maximize suspension travel and articulation, which is essential for off-road performance. The rear Stealth Shocks are engineered with a monotube design, providing consistent damping and improved heat dissipation for sustained off-road use. Overall, this system combines robust construction with precise engineering to deliver a reliable upgrade that enhances your truck's off-road capability and on-road handling.

Performance & Sound

With this control arm system installed, you will notice improved suspension articulation, allowing your vehicle to navigate rough terrain more confidently. The increased caster and camber correction help maintain proper tire contact with the road or trail, resulting in better steering response and stability. The rear Stealth Shocks provide superior damping, reducing body roll and absorbing impacts for a smoother ride. While this system is primarily designed for off-road performance, it also enhances daily driving comfort by offering a more controlled and responsive suspension feel.
