406402 – 1968-1970 GM A-Body Corner Max Kit, Race, Street Handling, Factory Spindles

UMI’s Corner Max front end kits provide a comprehensive system of high-performance parts engineered for optimal corner carving. The kit includes geometry-corrected A-arms with tall ball joints, higher-rate springs, Viking shocks, a heavy-duty sway bar, and a bump steer kit. The coilover-only lower A-arms feature caster improvement, tall ball joints, and allow the removal of the spring and shock without disassembling the spindle. The upper A-arm includes rod ends for smooth operation and adjustable settings without shims.

Additionally, the kit features a 1-5/16” sway bar upgrade with fabricated end links that reduce body roll and improve transitions. Racing coilover springs and Viking shocks provide exceptional handling, while the UMI bump steer kit allows for fine-tuning. The Corner Max kit enhances the performance of the stock GM clip with an easy bolt-on installation.

All UMI Performance parts are proudly fabricated and tested in Philipsburg, PA, USA. This kit provides exceptional handling at a 0-2” lowering and works with factory spindles. It allows for up to 10 degrees of static caster without relocating the spindle pin, and up to 1.2 degrees of camber gain per inch. The kit includes ½” tall lower and 0.9” tall upper ball joints for improved performance.

The unique quick-change system simplifies swapping shocks and springs at the track. With 850 lb/in race-proven spring rates, Viking shocks, and a 1-5/16” solid sway bar with swivel end links, the kit offers a balanced setup for optimal performance. It also includes a bump steer kit for fine-tuning, thrust bearings, and an adjusting wrench for easy height changes. Raced and tested on UMI’s 1972 LeMans test car, all UMI suspension components are proudly designed and manufactured in the USA.
