Vehicle Fitment

• 1973-1987 Chevrolet 1/2-Ton Pickup and SUV, 4WD, with 56 in. rear springs
• 1973-1987 GMC 1/2-Ton Pickup and SUV, 4WD, with 56 in. rear springs

Fitment Notes

• Specifically designed for use with 56 in. rear springs - confirm your truck's rear spring length before ordering, as Skyjacker offers other kit variants (such as 52 in. spring versions) for different rear spring configurations
• This kit includes Skyjacker's Black MAX shocks (front and rear) - the "-B" suffix denotes this shock package, distinct from the -H (Hydro), -M (M95 Performance), and -N (Nitro) shock variants of this same kit

Features

• Complete front-and-rear suspension lift package: front and rear leaf springs, front/rear U-bolt kits, bushing kit, and matched Black MAX shocks all included in one kit
• Black MAX shocks use advanced foam-cell technology, compressing to compensate for oil expansion as the shock heats up, maintaining consistent damping performance
• StableSteer valving on the Black MAX shocks ensures maximum tire-to-road contact for a smooth, controlled ride
• Front and rear leaf springs deliver the full 4 in. of lift while maintaining comfortable, factory-like ride quality
• Designed to respond well to both on-road and off-road conditions without sacrificing everyday drivability

Product Description

The Skyjacker C140AKSD-B is a complete 4 in. front-and-rear suspension lift kit for 1973-1987 Chevrolet and GMC 1/2-ton 4WD trucks and SUVs running 56 in. rear springs, bundled with a full set of Skyjacker's Black MAX shocks. Rather than sourcing lift components and shocks separately, this kit combines everything needed for a matched, complete suspension upgrade in one package.

Both front and rear leaf springs deliver the full 4 in. of lift while preserving comfortable, factory-like ride quality, paired with front and rear U-bolt kits sized for the 56 in. rear spring configuration. The included Black MAX shocks use advanced foam-cell technology that compresses to compensate for oil expansion as the shock heats up under hard use, keeping damping performance consistent rather than fading, while StableSteer valving keeps tires firmly planted on the road for controlled, predictable handling both on-road and off.

Everything ships together with a bushing kit and all necessary mounting hardware, along with detailed installation instructions, giving GM 1/2-ton owners a complete, ready-to-install 4-inch lift package rather than a piecemeal build. Buyers should confirm their truck uses 56 in. rear springs before ordering, since Skyjacker offers separate kit variants for other rear spring lengths. The kit is backed by Skyjacker's limited lifetime warranty.
