UMI Performance 2527-B Adjustable Rear Trailing Arms with CrMo Rod Ends

The UMI Performance 2527-B is a pair of on-car adjustable rear trailing arms engineered for serious performance driving. Built with race-quality rod ends, these arms deliver the lowest possible deflection and maximum articulation, making them ideal for drag racing, autocross, and road racing applications. Unlike rubber or polyurethane bushing designs, the precision rod ends eliminate compliance from the rear suspension, providing a direct, responsive connection between the chassis and the wheel.

Each arm is constructed from strong 1-1/4" chromoly (CrMo) steel tubing paired with heavy-duty 1/4" CNC laser-cut mounting brackets for outstanding structural rigidity under high-load conditions. The UMI-built CrMo on-car adjuster allows length changes to be made while the arms remain installed on the vehicle — no full disassembly required — making corner-weight and pinion-angle tuning fast and straightforward at the track.

Key Features:

• On-car adjustable design — adjust arm length without full removal
• Race-quality rod ends for zero deflection and maximum articulation
• 1-1/4" chromoly (CrMo) steel tube construction
• Heavy-duty 1/4" CNC laser-cut steel mounting brackets
• UMI-manufactured CrMo on-car adjuster for easy, secure adjustment
• Race proven and track tested
• 100% manufactured, tested, and raced in Philipsburg, PA — USA

Important Note: The 2527-B trailing arms with rod ends are intended for competition use — drag racing, autocross, and road racing. They are not recommended for street use, as the rod-end design may transmit increased road noise and NVH into the cabin. For a street/track dual-purpose option, consider the UMI Roto-Joint trailing arm alternative.

Sold as a pair with a durable black powder coat finish. Built entirely in the USA by UMI Performance.
