Jeep Wrangler JL 2-Door 2018-2026, TeraFlex 4.5in Sport ST4 Suspension System, No Shocks

A 4.5in lift gets a 2-door Wrangler into bigger tires, but only if the steering geometry and braking behavior survive the extra height. Piecing together springs, brackets and bump stops risks a mismatch.

The TeraFlex 4.5in Sport ST4 Suspension System bundles lift coil springs, Sport frame brackets for the front control arms, front lower and rear lower track bar brackets, progressive bump stops, strike pad extensions and shims, front sway bar quick disconnects, rear sway bar links and a front brake line anchor kit. The frame brackets restore caster and reduce brake nosedive. Installation is bolt-on, with no cutting or welding.

Install the kit, add Falcon Performance Shocks, and the Jeep rides higher on the street and on the trail.
