73-87 Chevy & GMC C10 Rear Axle Flip Kit (Bolt-On)

73-87 Axle Flip Kit - #130-4001

This bolt-on rear axle flip kit is designed for 1973-1987 Chevy & GMC C10 trucks equipped with the factory 3-inch rear axle tube diameter. By relocating the axle above the leaf springs, this kit provides an approximate 5-inch rear drop, lowering the truck’s stance while maintaining proper suspension geometry and street-friendly drivability.

Fitment is engineered specifically around OEM-style GM rear axle housings used in 73-87 C10 trucks, ensuring proper seating, clamping force, and alignment on factory leaf-spring rear suspensions. No cutting, welding, or modification to the axle housing is required for installation.

All structural components are fabricated from 1/4-inch thick steel plate for strength and long-term durability, then finished in a black powder coat to resist corrosion. The kit includes yellow zinc–plated hardware for a reliable, corrosion-resistant bolt-on installation.
