1963-1996 C2-C4 Rear Spring Rubber Cushions 4 Piece Kit 3831586 - OEM Number(s) (3831586)
Restore Ride Height and Eliminate Rear Suspension Noise
Bring your Corvette’s suspension back to factory performance with our 1963–1996 Rear Spring Rubber Cushion Kit. These cushions insulate the rear leaf spring from the suspension arms, preventing noise, restoring proper ride height, and reducing uneven tire wear. Over time, original cushions compress and fatigue under the car’s weight, leading to squatting rear stance and compromised handling. This 4-piece reproduction kit ensures your Corvette sits right and drives with confidence.

1963–1967 Corvette C2

Because Details Matter
Every Corvette tells a story through the way it drives. Rear suspension cushions may be small, but when they fatigue, the difference in stance, handling, and comfort is undeniable. Replacing them ensures your car sits as Chevrolet engineered it—level, tight, and ready for the road. Don’t let worn rubber compromise your driving experience, because details matter.
