Alpine RT Suspension Systems and Alpine IR Control arms with our Independent Rotation Bushings are available for JL and JK Wrangler/Unlimited and JT Gladiator models.
1534200 – JL 2dr: 4.5” Alpine RT4 Long Arm Suspension System – No Shocks
TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components.
Innovative, maintenance-free Independent Rotation (IR) Bushings remove bushing bind during full suspension travel for less overall bushing load during articulation resulting in unrestricted droop as well as a noticeable ride improvement whether on the highway or the trail.
These systems excel on the highway, off-road, through the desert, or rock crawling! If that sounds impossible, just remember it’s a TeraFlex suspension system built on decades of research and development resulting in the ultimate suspension with a lifetime warranty.
Alpine RT Suspension Systems are for the Jeeper who wants it all!
Wait a second... Alpine IR Control Arms for the JK Wrangler/Unlimited!?
That's right, we haven't forgotten about the JK!

1310512 – JL 2dr: Alpine IR Long Control Arm & Bracket Kit – 8-Arm (3–6” Lift)
After years of testing, TeraFlex has perfected our all-new IR (Independent Rotation) Bushings. These innovative bushings are included in our new long and short adjustable Alpine IR Control Arms for JL and JK Wrangler/Unlimited and JT Gladiator models.
Although traditional rubber bushings offer quiet operation and satisfactory longevity, their limitations began to surface during off-road driving and extreme articulation. Suspension bushings must twist as well as rotate, which causes suspension bind. The effects worsen as lift height and suspension travel increases.
TeraFlex IR Bushings end the industry-wide struggle to engineer zero maintenance bushings
with unrestricted droop. IR Bushings feature an innovative inner sleeve that freely rotates
360 degrees without placing load on the bushing. The internal contact surfaces of the rotating
sleeve feature an extremely tough, hardened bearing surface that is factory lubricated and permanently sealed. IR Bushings remove bushing bind during suspension compression whether on the highway or the trail. This results in a noticeable ride improvement. Eliminating rotational stress reduces bushing failure. The free movement of the IR Bushing extends its life span.
