🧾 Overview
The TeraFlex JL 4-Door 3.5 Inch Coil Spring Base Lift Kit is a foundational lift solution designed to provide increased ride height and tire clearance using only essential lift components. Unlike complete suspension systems, this base kit focuses strictly on achieving lift and is intended for builders who plan to add additional geometry-correcting components separately.
This kit does not include control arms or adjustable track bars required to fully optimize suspension geometry. For proper drivability, TeraFlex recommends pairing this base lift with longer front lower sport control arms, front control arm sport brackets, or adjustable Alpine (IR) control arms, along with front and/or rear HD forged adjustable track bars.
Note: Shocks are not included. Falcon Performance Shocks or TeraFlex 9550 VSS Twin-Tube Shocks are recommended, as they are engineered specifically to work with TeraFlex lift coil springs.
