Restore Strength Where It Counts
This Trailing Arm to Bearing Support Bolt Set is essential when you're rebuilding the rear suspension on your 1965–1982 Corvette. The knurled shoulder bolts are factory-correct style and feature a phosphate and oil finish for corrosion resistance and authenticity. These secure the rear spindle support to the trailing arm, with additional hardware fastening the parking brake backing plate. For a restoration you can trust—down to the last bolt—this 12-piece set delivers both performance and peace of mind.
