What it solves

Resolve clearance issues on your classic muscle car with UMI Performance’s 4068 Front Sway Bar Relocation Kit. Precision CNC-machined from solid 0.75-inch 6061 billet aluminum with a corrosion-resistant black anodized finish, these adapter mounts move your front sway bar bushing mounts forward by 0.745 inches while providing a 0.75-inch bar drop. This added clearance prevents contact between the sway bar and replacement idler arms with oversized pivots or larger-diameter aftermarket sway bars.

Engineered for 19641977 GM A-Body platforms including Chevelle, LeMans, Cutlass, and Skylark, the 4068 kit features slotted mounting holes to fit both 2-9/16 inch and 2.75 inch center-to-center chassis hole patterns. Each complete kit includes two relocation adapters (4068F) and Grade 8 hardware in both 5/16-inch and 3/8-inch threads for a direct bolt-on install without drilling. Road and track tested at UMI Motorsports Park, this kit is 100% made in the USA.

Decision guide

UMI 4068 relocation mounts solve front suspension clearance conflicts on GM A-Bodies, creating the space needed for oversized idler arm pivots and heavy-duty front sway bars. By moving the bar forward and dropping it slightly, drivers eliminate annoying component contact while maintaining proper bar operation for street or track driving.
