Classic Performance Products Rear Axle Flip Lowering Kit Chevy/ GMC Truck 47-54/ 4” Drop/ Weld-On

Modernize your classic truck's rear suspension while achieving a lowered stance with the Classic Performance Products rear axle flip conversion lowering kit for 1947-1954 1/2-ton Chevy and GMC Trucks. It simplifies the conversion from an original enclosed driveshaft rear axle to a modern open driveshaft rear end. The factory leaf spring center bolt location positions a replacement rear axle approximately 1-1/2” too far forward, resulting in improper wheel placement within the rear wheel opening. CPP's specially designed axle seats feature indexing holes that allow the rear axle to be repositioned for improved alignment within the wheel well. Compatible with rear axles featuring 3” diameter axle tubes, this kit provides a practical solution for incorporating a modern rear end into your classic truck while improving its overall appearance and stance.
