Product Description
TeraFlex 4" Alpine PreRunner Long Arm Suspension System | No Shocks | 2 Door (Wrangler JK 2007-2018)
TeraFlex Alpine CT (Cross-Trail) Suspension Systems build on our Sport ST (Street & Trail) Suspension Systems. The TeraFlex 4" Alpine CT4 Prerunner Long Arm Suspension System includes all the components necessary for a purpose-built speed system. The Alpine CT4 Prerunner builds on the standard Alpine CT4 by adding heavy-duty suspension limit straps and front and rear SpeedBump Bump Stops tuned for high-speed travel.

- The Alpine CT4 Prerunner Long Arm Suspension System is built to handle high-speed off-road excursions! Speedbumps provide progressive compression during high speed suspension movement
- Our adjustable Alpine Long Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3-6" lifts. On higher lifts, Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the Alpine Long Control Arms.Extensive guessting and brackets to beef up critically weak areas and prevent potential damage
- The HD Forged Adjustable Front and Rear (4"+) Track Bars and Rear Track Bar Bracket improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.
- This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat.
- TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH).
- Alpine CT Suspension Systems are engineered for hardcore Jeeping without sacrificing weekday ride comfort!
- Does NOT include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Alpine CT4 Prerunner Suspension Systems are offered without shock absorbers. We recommend Falcon Series 3.3 Fast Adjust Piggyback Shocks – available separately.
- Estimated installation time: 20 hours
