With this JK 8-Long Arm IR Bushing Replacement Kit you can upgrade your existing Long Alpine and/or Sport Control Arms on your JK Wrangler/Unlimited to the same bushings as the new TeraFlex Long Alpine IR Control Arms.
After years of testing, TeraFlex has perfected their all-new IR (Independent Rotation) Bushings. These innovative bushings are included in the new Alpine IR Long/Short 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 and rotate, which can cause suspension bind. The effects worsen as lift height and suspension travel increase.
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 on both highway or trail. Resulting in a noticeable ride improvement. Eliminating rotational stress will reduce bushing failure. The free movement of the IR Bushing extends its life span.
