1956-1962 C1 Rear Spring RH Front Hanger Bracket Late Design 3731148 - OEM Number(s) (3731148)
Ensure proper rear suspension alignment and secure mounting on your late 1956–1962 Corvette with our RH (passenger side) Rear Spring Front Hanger Bracket. This OE reproduction mounts the front eye of the rear leaf spring to the frame and is built to match the factory bracket used on late-production 1956 through 1962 models. It bolts directly to the frame using four fasteners (not included) and accepts the front spring eye pin.
In mid-1956, General Motors updated the hanger bracket design to improve shackle angle and suspension stability. This later version features a reduced height and repositioned mounting eyelet—both of which help deliver smoother handling and correct geometry.

Because Details Matter
This late-style hanger bracket restores proper suspension geometry for C1 Corvettes from mid-1956 through 1962. It’s the right choice for restorers focused on safety, performance, and originality—especially when replacing rusted or missing frame components.
