4 Inch Lift Kit | Chevy/GMC 1/2 Ton Truck/SUV (73-76) 4WD

Built for classic truck owners who want commanding ground clearance without sacrificing the original character of their rig. This 4-inch lift kit raises your 1973–1976 Chevy or GMC half-ton — including C10, K10, Suburban, K5 Blazer, and full-size Jimmy — while preserving the geometry and driveline angles that keep these trucks running straight. Choose between a simple block kit or a complete leaf-spring package, then dial in your shock preference for the ride you want.

What you get up front

• Coil-spring block spacers or leaf-spring extension — Lifts the front axle 4 inches with minimal angle change. Block kits bolt straight in; leaf-spring upgrades give you fresh springs and correct caster.

Pick your shocks

• BDS NX2 Nitro — Durable, predictable performance for highway and light trail use. The value choice for drivers who just want the lift and dependable damping.
• FOX 2.0 Performance Series — External-reservoir shocks tuned for classic truck ride quality. Better bump control and heat dissipation if you spend time on rougher roads or tow regularly.
