Zone Offroad C17N Suspension Lift Kit with Nitro Shocks for Chevy/GMC Ton - 4-Inch Black 3/4 4WD

The Zone Offroad C17N is a complete 4-inch suspension lift kit engineered specifically for 1973–1976 Chevy/GMC K2500 3/4-ton 4WD trucks and SUVs. This comprehensive kit delivers serious ground clearance and opens up room for tires up to 35 inches, giving your classic truck the stance and capability it deserves — all while maintaining a smooth, factory-consistent ride quality.

At the core of this system are heavy-duty front leaf springs featuring a 5-leaf pack design with anti-friction pads and center leaf spacer plates between each leaf. This construction significantly reduces internal leaf pack friction for a smooth and consistent spring rate over varied terrain.

Key Features:

• 4 inches of suspension lift for increased ground clearance and larger tire fitment (up to 35")
• Black Nitro Series shock absorbers — nitrogen-pressurized for improved compression and extension damping
• 5-leaf front spring pack with anti-friction pads and center leaf spacer plates for smooth, consistent spring rate
• 4-inch steering arm included to restore factory drag link angle after lift
• Front and rear brake line relocation brackets allow re-use of factory brake lines
• Yellow zinc-plated U-bolts with high nuts and washers for front springs and rear lift blocks
• Rear 4-inch lift blocks with longer U-bolts for an easy installation and level stance
• Steering components included to maintain factory-consistent handling characteristics
• Bolt-on design with all necessary hardware and installation instructions included

Note on Auxiliary Shocks: Some 1973–1976 3/4-ton models were factory-equipped with a dual front shock setup. If your vehicle has factory auxiliary front shocks, optional auxiliary shocks must be ordered separately to complete the installation.

Zone Offroad backs this kit with a 3-year / 36,000-mile warranty on all hard parts and wearable items. Professional installation is recommended, as some applications may require minor trimming or drilling.
