Features & Product Details

TeraFlex Alpine RT (Rogue Trail) Suspension System Features:

Lift Height: 4"

Max Tire Diameter: 37"

Adjustable Alpine IR Long Control Arms & Brackets balance front caster angle and pinion angles as well as optimize rear pinion angle and tune anti-squat geometry for proper suspension alignment on 3-6" lift kits

Alpine IR Long Control Arms are constructed from durable 42mm x 4mm (upper) or 50mm x 5mm (lower) wall DOM tube for maximum strength

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 IR Long Control Arms

Alpine Long Arm Brackets are gusseted and reinforced for superior strength w/ reduced NVH compared to other long arm kits

Delivers true Rogue Trail (RT) performance

Dependable performance w/ zero worries

Positive, responsive handling w/ reduced NVH

Innovative IR Bushings provide unrestricted rotation and flex as well as excellent NVH damping

Maintenance-free IR Bushings improve on- and off-road ride quality and performance

HD Forged Adjustable Front and Rear (4"+) Track Bars and Rear Track Bar Bracket improve steering response, center axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling

Front SpeedBump and rear Progressive Bump Stops provide progressive compression during high-speed suspension movement

Coil spring retainers prevent the springs from unseating during full suspension travel

Full range of movement for off-road flex and articulation

TeraFlex Limited Lifetime Warranty against defects

Top-of-the-Line Components.

Don't settle for a ride that doesn't provide the comfort and control you expect. The Alpine RT4 suspension system from Teraflex provides a completely new driving experience. Combined with the HD Adjustable Front and Rear Track Bars, the Alpine RT4 provides full suspension adjustability both on- and off-road! You'll enjoy unrestricted droop on the highway and the precision handling you need when off-road.

NOTE(s):

Requires aftermarket wheels w/ 4.75” backspacing or less – or Offset Wheel Adapters (# 1055000) for stock wheels – NOT INCLUDED.

Does NOT include shocks. Recommended 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. Falcon shocks are available separately.

We highly recommend driveshaft modifications such as our High-Angle Rzeppa CV Driveshafts or our High-Angle Rzeppa CV Joint Kit (# 1744014).

Requires cutting/removal of factory control arm bracketry to install Alpine Long Arm Brackets.

Requires cutting and welding.
