Official Release:

UMI Performance, Inc. is pleased to announce the availability of our new P/N 4057 A-body rear coilover/control arm relocation kit. This 100% bolt-in kit uses UMI designed and manufactured brackets to provide both coilover attachment and lower control arm relocation. UMI’s laser cut brackets are JIG assembled and MIG welded to ensure a great fit and race-proven quality. The lower bracket features a double shear mount for reliability while the upper bracket reinforces the shock mount area. The 2-hole trailing arm adjustment enables fine tuning of instant center location for drag launch or auto-x/road race rear steer tuning. The 4057 brackets capture a Viking double adjustable coilover specific shock and a 150, 125 or 110 lb/in spring. We recommend 150 for auto-x and corner carving, 125 for general cruising and 110 for drag specific usage. Upgrades include Crusader Pro-Tour or Drag specific valvings as well as an optional shock tower reinforcement brace (P/N 4058-4059). UMI’s coilover brackets are also available separately in order to source your own spring and shock. This kit is generally used for 1-3” lowering from factory location and does not make any permanent changes to your axle housing or chassis. All UMI products are manufactured tested and raced out of Philipsburg, PA and always use US materials.

Features:

• 100-percent bolt-in installation
• JIG assembled and MIG welded
• Good for 1-3-inch lowering from factory location
• No permanent changes to axle housing or chassis
