Construction & Design

The control arms are constructed from high-strength steel and feature a durable, corrosion-resistant finish to withstand harsh off-road conditions and weather elements. The use of uniballs instead of traditional ball joints allows for greater articulation and reduces binding during extreme suspension travel. The design incorporates CAD-developed geometry to ensure proper caster and camber angles, which helps maintain optimal tire contact and steering response. The rear shocks are engineered with high-quality damping components to absorb impacts and provide a controlled ride, whether on or off the pavement.

Performance & Sound

This suspension upgrade enhances your truck's off-road capability by increasing wheel travel and improving suspension articulation. The system helps support increased load capacity and provides a more responsive steering feel.
