The TeraFlex 1" Front Coil Spring Spacer Adjustment Kit is the piece that levels the front of a JL Wrangler or JT Gladiator with the heavier 3.0L EcoDiesel V6 when you run a TeraFlex coil spring lift kit. On those trucks it is required, not optional. It also earns a spot on gas trucks as a 1" front load level kit.

Why it works

  • Levels EcoDiesel trucks: required with TeraFlex coil spring lift kits on 3.0L EcoDiesel V6 models.
  • Works on gas trucks too: use it as a 1" front load level kit to offset heavier gear like bumpers, a winch, a bigger spare or weekend swag.
  • Small, targeted fix: it corrects front height without changing the rest of your setup.

Pairs well with

TeraFlex recommends Falcon Performance Shocks or its 9550 VSS Twin Tube Shocks with this kit.

Fitment

Jeep JL Wrangler 2-door, JL Wrangler Unlimited 4-door and JT Gladiator. Browse suspension components or see Jeep Gladiator parts.

Install notes

TeraFlex estimates 1.5 hours of labor.

Questions before you order?

Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
