Use the TeraFlex JK: 8-Long Control Arm IR Bushing Replacement Kit to upgrade your existing adjustable Alpine Long Control Arms on your JK Wrangler/Unlimited to the same bushings as our new adjustable Alpine IR Long Control Arms. Can also be used to replace existing IR bushings. 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.

TeraFlex Full Suspension Systems
TeraFlex full suspension systems are complete, engineered lift solutions built specifically for vehicle. Rather than a simple spring-and-spacer lift, each system is designed as a matched package: progressive-rate coil springs, tuned shocks, control arms, track bars, sway bar links, and the brackets and hardware needed to keep geometry correct at the new ride height. The result is added ground clearance and room for larger tires without sacrificing on-road manners.
Falcon Shocks by TeraFlex
Falcon Shocks are TeraFlex’s performance shock line, engineered from the ground up for specifically for your application. Each shock is a high pressure monotube design with a large diameter body, hard-chrome piston rod, and application-specific valving tuned to the weight, geometry, and suspension travel of the vehicle it’s built for—so the damping is right out of the box, whether your ride is stock height or lifted.
The lineup scales with how you drive. Entry-level monotubes sharpen control and comfort for daily driving and light trails, mid-tier models add larger bodies and more oil capacity for sustained off-road use, and top-of-the-range piggyback-reservoir shocks offer tool-free adjustable damping—plush for the highway, firm for towing, and full performance for desert and rock terrain.
TeraFlex Brake Kits
Bigger tires and added weight overwhelm factory brakes, so TeraFlex brake kits are engineered to restore and improve stopping power on lifted Jeep Wrangler and Gladiator models. The lineup ranges from bolt-on performance rotor and pad upgrades to complete big brake kits with oversized rotors, high-capacity calipers, and platform-specific brackets for greater clamping force and heat dissipation—plus extended braided stainless brake lines for lifted, long-travel suspensions. Every kit installs without cutting or fabrication and is built to handle off-road abuse, giving you stopping performance that matches your build, whether you’re on 35s or 40s.
