4 inch Lift Kit – 2020-2021 Jeep Gladiator, including the Rubicon featuring Dual Rate Coils with or without Fox Shocks  

Superlift’s all-new Dual Rate Coil Springs 4 inch lift kits for the 2020-2021 Jeep Gladiator JT is the first 4 inch lift kit on the market with replacement dual rate coil springs that are location specific. Through specialized testing, Superlift’s engineers determined that the same coil spring rate cannot be used side to side. These new dual rate coil springs will provide excellent ride quality on-road while allowing more extension for off-road use. These new dual rate coils will also provide an even stance and long lasting durability.

Superlift’s all new Dual Rate coil springs will give your Jeep Gladiator the ride, stance, and durability it desires. Each Dual rate coil features a transition of two rate ranges that give you that ultimate ride on pavement with the flexibility and durability of off-road performance.

To complement these new dual rate Gladiator coil springs, the kit also includes front adjustable track bar, shock extension brackets or Fox Shocks, compression stop spacers, and extended sway bar links. The Fox Shocks or shock brackets allows the maximum amount of extension travel without drive shaft bind and the compression stop spacers prevent tire rub during full compression.

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.
