1956-1962 C1 Rear Spring LH Front Hanger Bracket 3731147 - OEM Number(s) (3731147)

Restore your Solid Axle Corvette's suspension integrity with this exact reproduction 1953–Early 1956 Rear Spring LH Front Hanger Bracket. Designed for the driver side, this bracket mounts the front of the rear leaf spring to the frame, supporting safe and correct rear suspension articulation. Made from heavy-gauge stamped steel, this OE-style bracket offers factory fit and function for accurate restoration or long-term service.

In early 1956, Chevrolet redesigned the rear spring hanger brackets to improve rear shackle angle and handling characteristics. This early-style bracket features the correct original height and lower shackle pivot point seen on 1953 through early production 1956 models.

Features
• Original Equipment reproduction for 1953–Early 1956
• LH (driver side) application
• Heavy-duty stamped steel construction
• Mounts to chassis with 4 bolts (not included)
• Accepts front spring eye pin for leaf spring mounting
• Supports correct rear suspension geometry and shackle angle

Because Details Matter
GM introduced revised hanger brackets during the 1956 model year to improve handling. This early-design bracket matches the original fitment and geometry of 1953 through early 1956 Corvettes. Whether you're restoring a factory-correct NCRS car or rebuilding your street-driven C1, this bracket is the first step toward safe, correct rear spring support.
