U-Bolt Set for 4" Blocks (w/ Overload Springs) - 1995-1999 Chevy/GMC C2500/C3500/K2500/K3500

This Trekline U-bolt set is engineered for 1995-1999 Chevrolet/GMC C2500, C3500, K2500, and K3500 trucks running 4" rear lift blocks, with factory overload leaf springs. Correctly sized U-bolts are critical after a rear block install — factory-length U-bolts will not properly clamp the axle to a taller block and can allow axle wrap or spring shift under load. Sold as a set for one axle. Professional installation recommended.
