Quadratec's Maximum Duty 2.5" Suspension Lift Kits for Jeep Wrangler JL's are an excellent means of fitting taller tire packages without breaking the bank or sacrificing quality. Our Wrangler JL kits proudly pass the rigorous FMVSS 126 physical testing that accurately measures how the vehicle reacts after this suspension modification. 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. Quadratec's Maximum Duty Coil Spring Suspension Kits add an additional 2-1/2” of suspension making our kits an excellent choice for fitting up to 35” tall tires on non-Rubicon models and 37” tires on a Rubicon. Our premium kits replace all four factory length coil springs with our longer Maximum Duty Dual Rate Coils. Our coil springs are wound using a premium steel alloy to ensure consistency and are preset to add memory and eliminate settling. Our Dual Rate Long Travel coil springs are specifically designed for the JL Wrangler and have excellent road manners with exceptional off-road capability. Dual Rate Coils are designed to expand with off-road articulation and drop when needed to maintain traction. Our Kits come complete with front shocks, rear shock, front coil springs, rear coil springs, front extended sway bar links, rear extended sway bar links, front bump stops, rear bump stops, and grade 8 hardware. Kits are available with a choice of Maximum Duty Hydro 7.0 or Nitro 8.0 shock absorbers. Kits are also available with Fox Racing’s 2.0 Performance Series IFP shock absorbers. Our kits include excellent installation instructions with step-by-step photos making it easy to install with basic skills and hand tools.

Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.

      Wrangler JL: The Quadratec 2.5in Suspension Lift Kit is designed specifically for the Wrangler JL. Quadratec offers two different versions for the Rubicon and the Sport or Sahara trim packages.

      Shock Options: Select from Quadratec's Nitro or Hydro shocks. 8.0 Nitro shock absorbers are recommended for moderate to extreme off-road use and provide a firmer ride over stock shocks. The internal components instantly respond to any change in driving conditions and the 150 psi high-pressure nitrogen gas shocks are our fastest responding shocks. 7.0 Hydro shocks are recommended for mild to moderate off-road use. The internal components instantly respond to any change in driving conditions. The true velocity sensitive valving produces a stable and controlled level of resistance for improved handling and stability while maximizing ride comfort.

      Bolt-On Installation: For ease of installation, the Quadratec 2.5in Suspension Lift Kit mounts to your Jeep without cutting, drilling, or other modification. This kit comes complete with front and rear coil springs, bump stops and sway bar links.

      Run Larger Wheels and Tires: With this kit, you will be able to fit 35x12.50 tires 35” tall tires on non-Rubicon models, and 37” tires on a Rubicon. If you plan on using factory wheels, then you will need to check for clearance on the sway bar end links and control arms.
