Precision-Engineered Long Arm Geometry for Enhanced Control
The foundation of this lift system lies in its tubular long arms, which reduce caster changes throughout the suspension’s travel. These extended control arms provide a more stable and consistent feel in the steering wheel and preserve the factory arm triangulation for superior suspension stability. Heavy-duty control arm mounting brackets ensure proper alignment and structural integrity under heavy loads or aggressive off-road use.
Front Suspension Built for Diesel-Specific Performance
Included in the front suspension are high-strength, progressive rate Pro-Ride coil springs engineered specifically for diesel engines. These springs deliver excellent ride quality across varying terrains. Also included are four long control arms, precision-engineered mounting brackets, a forged drop pitman arm, and a track bar relocation bracket for proper steering geometry. Bump stops and sway bar links help maintain control and ride stability, while the NX2 Nitro or FOX 2.0 IFP gas shocks ensure superior damping performance.
Rear Suspension with Heavy-Duty Cast Blocks
At the rear, the system includes 4-inch heavy-duty cast steel lift blocks, extended U-bolts, and matching NX2 Nitro or FOX 2.0 Performance shocks. This combination maintains proper rake while improving towing stability and off-road articulation. The entire system is built for long-lasting durability and seamless integration with the factory axle configuration.
