Quadratec's Maximum Duty Suspension Lift Kits just got a whole lot better! We've teamed up with FOX Shocks to engineer a perfectly tuned and valved shock specifically designed for our Maximum Duty Suspension Kits. Fox IFP Mono-Tube shocks contain the latest in technology to transform the performance of your Wrangler. They use race-proven damping control to provide a comfortable on-road ride and predictable offroad handling in even the toughest conditions. The precision metal impact aluminum body increases cooling capacity and will never rust. The Internal Floating Piston (IFP) mono-tube design separates the shock oil from the high-pressure, nitrogen-charged gas chamber. The IFP eliminates oil aeration allowing maximum performance! Quadratec's Maximum Duty Coil Spring Suspension Kits add an additional 3-1/2” of suspension and an excellent choice for fitting up to 33” tall tires. These premium kits replace your four factory length coil springs with our longer Maximum Duty Coils. Our coil springs begin with premium steel alloy material to ensure consistency and are preset to add memory and eliminate settling. Each spring CNC wound and then load tested to certify consistency through the spring's complete travel cycle. Our progressive rate coil spring are engineered to be within 10% of the factory rates with all the vigorous off-road handling capabilities while maintaining the smooth factory-like characteristics. Coil springs are easy to install with simple hand tools and do not require a spring compressor. The 3-1/2” Coil Spring Lift Kits include four Quadratec exclusive shock absorbers to help maximize both the street performance and off road capabilities. Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
