6-Inch Front and Rear Spring Lift Kit for Chevy/GMC 4WD (1973-1976)

About this kit

6-Inch Front and Rear Spring Lift Kit, fitment-checked

Both ends get new springs here: 6-inch front and rear leaf springs, a raised steering arm, and two N3 shock pairs for 1973-1976 Chevrolet and GMC 4WD trucks and SUVs. It fits only trucks with 52-inch rear leaf springs, so measure eyelet to eyelet before ordering. Tire clearance runs to 37 inches.

Replacing both leaf packs rather than adding to the rear, the 12630 raises 1973-1976 Chevrolet and GMC 4WD trucks and SUVs — Blazer, K5 Blazer, K10, K15, Jimmy, and the Suburban variants — by 6 inches. The rear springs are cut for a 52-inch eyelet-to-eyelet measurement, so confirm yours before ordering. A raised steering arm and two N3 shock pairs round out the package, and Rough Country publishes a downloadable installation guide. Budget 6-8 hours. Add drop brackets, part 1019, if your truck runs a factory front sway bar; quad-shock trucks use a single aftermarket shock per side.
