Jeep Wrangler JL 4-Door 2018-2026, TeraFlex Alpine RT Coilover Suspension System, 392, F60/R60 Axles

Coilover shocks promise a big step up, but many bring spring twang, slider slap, clicking and mount squeaks. A Rubicon 392 owner wants the upgrade without the noise.

The TeraFlex Alpine RT coilover system is built for the 4-door JL Rubicon with the 392 powertrain, with front and rear Falcon coilovers (13in stroke) and a 4.5in lift with plus or minus 1.25in of adjustability. Falcon 3.3 series Quick Adjust tuning, JL-specific springs and sealed gimbal lock bearing mounts keep it quiet. This version is for front and rear HD 3.25in diameter axles.

Bolt on the coilover brackets, set the ride height, align, and the 392 gets a quiet long-travel suspension.
