Quadratec's Maximum Duty Suspension Lift Kits provide a complete selection of lift options for budget-minded enthusiasts who want to transform the look and performance of their Wrangler. Our value-priced kits provide an economical means of fitting taller tire packages without breaking the bank. Our JK kits proudly pass the rigorous FMVSS 126 physical testing that accurately measures how the vehicle reacts after our suspension modifications. Test results prove that our suspension kits work in harmony with the Electronic Stability Control (ESC) system and retain the effectiveness for both vehicle performance and safety to reduce rollovers. Our kits come with excellent installation instructions with step-by-step photos and are easy to install with basic skills and hand tools. Quadratec's Maximum Duty Coil Spring Suspension Kits add an additional 2-1/2" of suspension and are an excellent choice for fitting up to 34" 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 springs are engineered to be within 10% of the factory rates with all the vigorous off-road handling capabilities while maintaining smooth factory-like characteristics. Coil springs are easy to install with simple hand tools and do not require a spring compressor. The 2-1/2" Coil Spring kits include four Quadratec exclusive shock absorbers to help maximize both the street performance and off road capabilities. These complete kits are available with your choice of Hydro 7.0 or Nitro 8.0 shock absorbers and come complete with all the necessary hardware and brackets to retain proper vehicle alignment. Fully detailed installation instructions included.
