The TeraFlex 3.5-inch coil spring base lift kit in brief

Front lower 2 in, rear upper 1.5 in and rear lower 0.5 in: those are the figures TeraFlex prints for its 3.5-inch coil spring base lift kit, next to an overall lift of 3.5 in. The maker states no rear lift value. This is a full suspension lift listed under one part number, 1365000, for the Jeep Gladiator JT pickup in 4WD, the only drive the Gladiator is sold with. The largest tire the maker lists is 37 in, with 35 in for Sport or Overland fenders and 37 in for Rubicon fenders. Shocks are not included. TeraFlex requires longer shocks and says its Falcon shocks are engineered to work with its lift coils. Alignment is required, caster correction is required and not included, and install time is about 5.5 hours. TeraFlex states no fitment years, so the kit is listed here for the 2020-2026 Jeep Gladiator.
