Construction & Design

The control arms are constructed from forged aluminum, combining lightweight design with exceptional strength. The dual-rate coilovers feature a monotube construction with a threaded body for easy height adjustments and damping control. The rear shocks are designed with a durable, corrosion-resistant finish to withstand off-road elements. All components are engineered with precision CAD modeling and TIG welding to ensure perfect fitment and long-lasting durability. This system's design emphasizes improved articulation, reduced stress on other suspension components, and enhanced overall ride quality.

Performance & Sound

With this suspension upgrade, expect noticeable improvements in off-road capability and on-road handling. The adjustable coilovers allow you to tailor the ride height and damping to match your driving style and terrain conditions. The increased wheel travel and ground clearance enable better obstacle clearance and a more commanding stance.
