Zone Offroad C22N Suspension Lift Kit with Nitro Shocks for Chevy/GMC Ton - 6-Inch 3/4 4WD 77-87

The Zone Offroad C22N is a complete 6-inch suspension lift kit designed for 1977–1987 Chevy and GMC 3/4 ton (K2500) 4WD trucks and SUVs. This comprehensive system delivers the ground clearance and aggressive stance needed for serious off-road use while maintaining daily-driving reliability. The C22N variant includes Zone Nitro shocks for improved ride quality over the standard kit.

Key Features:

• Provides 6 inches of front suspension lift for dramatically increased ground clearance
• Rear lift achieved via a 4-inch lift block and add-a-leaf combination, yielding 5–6 inches of rear lift
• Includes a 4-inch steering arm to correct the drag link angle after the lift
• Front and rear brake line relocation brackets included to accommodate the increased ride height
• Yellow zinc-plated U-bolts with high nuts and washers included for front and rear
• Steering components included to maintain factory-consistent vehicle handling characteristics
• Zone Nitro shock absorbers included for improved damping performance
• Kit manufactured in the USA with premium materials and skilled workmanship
• Installer-friendly instructions with detailed photos, diagrams, and helpful hints

Important Installation Notes:

• On some models, the front driveshaft may need to be clearanced at the double cardan joint to prevent binding
• Some models may require the optional transfer case drop kit (Zone part# C5001) to alleviate driveshaft vibration
• The front exhaust cross-over pipe may need to be modified to clear the front driveshaft on some models
• Vehicles equipped with factory auxiliary front shocks will require additional auxiliary shocks (sold separately)

Zone Offroad backs this kit with a limited lifetime warranty, making the C22N a confident, long-term investment for classic Chevy and GMC 4WD owners looking to run larger tires and tackle more demanding terrain.
