Maximum Duty 2.5in Coil Spring Suspension Lift Kits are an excellent means to fitting taller tire packages without breaking the bank or sacrificing quality. Our 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 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.
