TeraFlex | 18-Up Wrangler JL 4 Door Alpine RT Coilover Suspension System 2.0L

The Alpine RT Coilover System is the ultimate suspension solution designed specifically for the JL Wrangler 4-Door. Whether you are looking for a complete suspension overhaul or a high-performance upgrade to an existing long-arm system, this setup delivers race-inspired performance, increased vehicle stability, and unmatched dynamic roll control.

Engineered to eliminate the common annoyances of traditional coilovers, these systems focus on utterly silent operation. By addressing issues like "Spring Twang," "Zipping," and "Slider Slap," this system ensures your off-road adventures aren't interrupted by suspension noise. The hard-anodized shock bodies and sealed, lubricated spring sliders provide a smooth bearing surface for noiseless movement during full suspension cycling, while sealed Gimbal Bearing shock mounts ensure solid, rattle-free control.
