EMPI Rear IRS A-Arm Bushing Kit | VW Beetle & Karmann Ghia (IRS) | Performance Urethane w/ Sleeves (B6-5570-0)

Rear IRS A-Arm Bushing Kit — Performance Urethane with Steel Sleeves (B6-5570-0)

Lock in your alignment and eliminate suspension slop with the Rear IRS A-Arm Bushing Kit. On vehicles with Independent Rear Suspension (IRS), the factory rubber bushings are often a weak link: over time they allow excessive vertical movement at the pivot point — a problem magnified at the end of the arm, leading to unpredictable handling and ruined wheel alignments.

These high-density urethane bushings replace the inner sleeve and soft rubber cushion of your stock bushings. Upgrading to urethane effectively freezes the pivot point in its intended position, keeping your alignment specs exactly where they belong even under heavy cornering loads.
