About this kit
6-Inch Front and Rear Spring Lift Kit, fitment-checked
A full-spring 6-inch lift for 1973-1976 Chevrolet K20 and K20 Suburban and GMC K25, K2500, and K25 Suburban 4WD: new leaf packs at both ends, a raised steering arm, u-bolts, and two N3 shock pairs. It fits only trucks with 52-inch rear leaf springs.
Both leaf packs are replaced here, so the 12830 sits 6 inches higher on new front and rear springs rather than on blocks or an add-a-leaf. It covers 1973-1976 Chevrolet K20 and K20 Suburban plus GMC K25, K2500, and K25 Suburban 4WD models, and only those with 52-inch rear leaf springs. A raised steering arm corrects the steering geometry that comes with the new height, u-bolts and front installation hardware are supplied, and two N3 shock pairs handle damping. Trucks with a factory front sway bar should add drop brackets, part 1019; trucks with factory front quad shocks need the separate quad shock kit.
