HD Forged Adjustable Track Bars (0–6” Lift)

Jeep axles experience tremendous amounts of lateral force while driving and/or turning and those effects increase exponentially during off-road driving. TeraFlex JK: HD Adjustable Track Bars withstand these abusive side loads to dramatically improve handling and/or steering response. These Track Bars also allow lateral adjustment of the axle for proper axle alignment as well as cycling through full suspension travel without interfering with other components. Our Rear Track Bar also maximizes rear right spring clearance without interfering with other components.

A must for anyone who takes their rig off-road!

 

FEATURES/BENEFITS

  • HD Forged Adjustable Track Bars are 230% stiffer than factory track bars — making them the strongest track bars on the market!

Control Arm Bushing – Sport/Alpine

These high-quality, dependable, maintenance-free, factory-style bushings provide excellent NVH (noise, vibration, and harshness) damping and ride quality.

IR Control Arm Bushing – Alpine IR

Use these TeraFlex JK: IR (Independent Rotation) Bushings to upgrade your existing Sport or Alpine Control Arms on your JK Wrangler/Unlimited to the same bushings as our new Alpine IR Control Arms. Can also be used to replace existing IR Bushings.

1952701 – JK: IR Bushing Kit – 8 Long Arms

After years of testing, TeraFlex has perfected our IR (Independent Rotation) Bushings. These innovative bushings are installed in our adjustable short and long Alpine IR Control Arms used in our JL and JK Wrangler/Unlimited and JT Gladiator Alpine RT Suspension Systems.

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 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 a 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.

Existing lift systems can also be upgraded to IR Bushings via our short and long Alpine IR Control Arm Kits. Or upgrade your existing short or long Alpine Control Arms with our complete IR Bushing Replacement Kits.

FEATURES/BENEFITS

  • Direct replacement for factory-style control arm bushings
  • Inner sleeve provides 360 degrees of rotation for unrestricted movement at full droop
  • Rotating sleeve features an extremely tough, hardened bearing surface
  • Eliminates rotational stress and reduces bushing bind
  • Provides excellent noise, vibrations, and harshness (NVH) damping
  • Improves on- and off-road ride quality and performance
  • Bushings are factory lubricated and permanently sealed
  • Zero maintenance
  • TeraFlex Limited Lifetime Warranty against defects

Track Bar Bushing

Replace your worn-out track bar bushing with the replacement TeraFlex JK: Track Bar Bushing. The press-in replacement bushing improves on the OEM-style rubber bushing by adding an additional rate plate for responsive handling and superior control. This high-quality factory-style bushing reduces the effects of front wheel shimmy and improves durability and tunability. Fits front or rear track bars at the axle or frame end.
