UMI Performance Suspension Parts

UMI Performance Adjustable Sway Bar End Links

UMI Performance adjustable front-end links directly replace the factory non-adjustable front sway bar end links. Adjustable end links allow you to adjust front sway bar preload and tune the front suspension. The sway bar end links are CNC-machined from 6061 T-6 aluminum for the utmost in strength and anodized black for long-lasting corrosion protection. Adjustments are made using the QA1 XM Series spherical rod end bearings, which prevent bind and allow the suspension to articulate correctly. The QA1 rod ends feature oil-impregnated PTFE lining which keeps the ball bearing lubricated at all times—allowing for quiet longevity. The adjustment of the sway bar end links are easily made on the car using right and left hand threads, and using the hex body as a turnbuckle.
