Zone Offroad C18N 4-Inch Full Suspension Leaf Spring Lift Kit with Nitro Shocks

The Zone Offroad C18N is a 4-inch full suspension lift kit engineered specifically for 1988–1991 Chevy/GMC 3/4-ton 4WD SUVs, including the K5 Blazer, V2500/K2500 Suburban, and GMC Jimmy (R/V series). This complete front-and-rear lift system uses a proven leaf spring and cast block design to deliver a level, aggressive stance with meaningful ground clearance gains for both street and trail use.

The kit includes Nitro Shocks—nitrogen gas-charged shock absorbers engineered to minimize shock fade and deliver consistent, smooth ride quality on- and off-road. Steering components are also included to maintain factory-consistent handling characteristics after installation.

Key Features:

• 4-inch front lift via heavy-duty replacement front leaf springs for excellent ride quality
• 4-inch rear lift via cast rear lift blocks and extended U-bolts for a level stance
• Nitrogen gas-charged Nitro Shocks included for improved damping and reduced shock fade
• Brake line relocation brackets allow reuse of factory brake lines
• High-strength, black e-coated U-bolts for durability and corrosion resistance
• Steering components included to ensure smooth, factory-consistent vehicle handling post-lift
• Supports up to 35-inch tires (e.g., 35x12.5) on compatible wheel sizes

This is a complete suspension lift solution—front and rear—delivering a full 4 inches of lift height at both axles. Zone Offroad products are built in the USA and backed by a lifetime warranty, making the C18N a reliable long-term upgrade for classic Chevy/GMC 3/4-ton SUV owners seeking greater off-road capability.
