UMI Performance 64-72 GM A-Body Rear Control Arm Relocation Brackets - Bolt-In

If you're looking to get better grip off the line and improve your classic GM A-Body's launch consistency, these rear control arm relocation brackets from UMI Performance are a solid option. Designed to work with factory 10-bolt and 12-bolt rear ends, they help optimize your vehicle's instant center, which is key for improving forward traction. This means less wheel hop and a more predictable launch, whether you're heading to the drag strip or just want a more planted feel on the street.

These brackets are CAD designed and CNC laser cut from 3/16" mild steel for a well-built, precise fit. They offer multiple adjustment holes, allowing you to choose a 2", 2-3/4", or 3-1/4" drop for the lower control arms. This adjustability is great for fine-tuning your suspension angle, especially on lowered vehicles, and UMI's track testing has shown an average 0.10-second reduction in 60-foot times. Installation is straightforward as they bolt directly onto the factory rear end housing without the need for drilling, cutting, or welding, and they accommodate both factory and most aftermarket lower control arms.

This kit includes new Grade 8 hardware and installation instructions. While adjustable upper control arms aren't required, they are recommended for the best possible alignment and handling setup. These brackets are designed to work with both factory-height and lowered vehicles, making them a versatile upgrade for a wide range of GM A-Body models from 1964-1972, including popular cars like the Chevelle, GTO, and Skylark.
