4 Inch Lift Kit | 52 Inch Rear Springs | Chevy/gmc C10/k10 Truck & Suv/k5 Blazer (73-76)

Built for classic Chevy and GMC truck owners who want a leveled stance, aggressive look, and the ground clearance to tackle bigger tires and obstacles — this 4-inch lift kit combines application-specific front and rear leaf springs with premium N3 Series shocks to deliver a smooth, factory-like ride both on-road and off. You'll gain enough clearance to run 33–35 inch tires while a raised steering arm corrects your geometry for responsive handling after the lift.

What's included

• 4-inch front leaf springs (qty 2) — engineered for perfect fit and optimal ride quality, delivering increased ground clearance without compromising suspension geometry.
• 4-inch rear leaf springs (qty 2) — application-specific design eliminates the need for rear lift blocks, ensuring consistent lift and improved suspension balance.
• Raised steering arm — corrects steering geometry to maintain precise handling and improved alignment after the lift.
• N3 Series shock pair (qty 2) — application-valved with 10-stage variable valving, high-pressure nitrogen charge, 54mm shock body, and 18mm piston rod for balanced on-road comfort and off-road control.
• Brake line relocation brackets — maintain proper alignment and safety throughout the suspension travel.
• U-bolts and hardware — all fasteners needed to secure components to your chassis.
• Front installation kit — includes brackets and hardware specific to your truck's mounting points.

Important notes

• This kit fits only vehicles with 52-inch rear leaf springs. Confirm your rear spring size by measuring eyelet-to-eyelet before ordering.
• If your truck is equipped with a factory front sway bar, Rough Country recommends drop brackets (SKU 1019) to maintain proper suspension geometry.
• Vehicles equipped with factory quad shocks (two shocks per side up front) will use a single aftermarket shock per side with this kit.
• Maximum tire clearance of 35 inches requires proper backspacing; work with our team to dial in the right wheel offset.
