The system includes vehicle-specific, performance-tuned Falcon 3.3 shocks at all four corners, ensuring a smooth ride and excellent handling even on challenging terrain. The coil spring setup not only increases ground clearance but also improves ride quality by maintaining optimal suspension geometry. An added benefit is the inclusion of tubular radius arms that help to correct caster angles, which is essential when lifting heavy-duty trucks for improved stability and steering response.
