UMI Performance GBR024-R Rear Pro-Tour Suspension Control Arm Kit with Roto-Joints

The UMI Performance GBR024-R is a complete pro-touring rear suspension control arm kit engineered for vehicles that demand both high-performance handling and everyday street comfort. Featuring UMI's proprietary Roto-Joint technology, this 8 Roto-Joint package delivers bind-free articulation, precise adjustability, and race-proven durability in a single convenient kit.

Key Features:

• Boxed lower control arms with dual Roto-Joints on each end for maximum articulation and strength
• TIG welded sway bar sleeves integrated into the lower arms for clean, secure sway bar mounting
• Fully adjustable upper control arms with Roto-Joints on one end, allowing precise pinion angle and lateral location tuning
• Roto-Joint rear axle housing bushings (UMI p/n 2999) for completely bind-free suspension movement
• Grade 8 hardware included — grade 8 bolts with nylock nuts for reliable, high-strength fastening
• Combines the feel of rod-end race suspension with the compliance needed for highway and street use
• 100% Made in the USA — manufactured with pride in Philipsburg, PA

The Roto-Joint design uses an adjustable ring and Delrin race insert that can be tightened over time to compensate for wear, extending service life well beyond traditional rubber or polyurethane bushings. The upper arms are fully adjustable for dialing in pinion angle and rear axle lateral positioning, making this kit ideal for pro-touring builds, restomod projects, and track-driven street cars alike.
