6 Inch Lift Kit | 52 Inch RR Springs | Chevy/GMC 3/4-Ton Suburban/C25/K25 Truck (77-87)

Upgrade your Chevy/GMC 3/4-ton rig from 1977–1987 with Rough Country’s 6" GM Suspension Lift System, engineered to level the front with the rear for a bold, capable stance. This isn’t just about height—it’s about maintaining a factory-like ride while delivering real off-road confidence and improved visibility on every road your truck faces.

What makes this kit stand out:

• Front lifted leaf springs provide added ride height without compromising ride quality or handling—so you get a commanding look without a rough, stiffer feel.
• Rear leaf springs (52" rear springs) and brake line brackets keep suspension geometry correct, preserving predictable handling and braking performance after the lift.
• Rough Country N3 shocks—10-stage variable, high-pressure nitrogen-charged dampers tuned for a balanced ride: smooth highway cruising with confident, controlled off-road action.
• Durable construction features an 18mm spring-loaded piston rod and a 54mm shock body for enhanced durability and faster cooling under demanding conditions.
• Fits up to 37" tires with proper wheel backspacing, giving you the freedom to choose a aggressive stance and extended ground clearance without rubbing.
• All-in-one kit included for a complete install experience, backed by Rough Country’s Lifetime Replacement Warranty.

Designed for Suburban, C25, and K25 models—this lift system respects your truck’s original geometry, keeping front-to-rear alignment and steering feel while offering a substantial upgrade in height and presence. It’s ideal for owners who tow, haul heavy payloads, or simply want the rugged, ready-for-anything look that turns heads on and off the highway.

Practical use cases:

• Off-road excursions where increased ground clearance and improved approach/departure angles matter
• Heavy-duty daily driving with better visibility and a more planted ride
• Custom tire setups up to 37" for a bold, aggressive look without compromising safety or handling

Why choose this kit over stock or alternative setups? It delivers a true leveling effect—front and rear height equalization—plus purpose-built springs and tuned shocks that preserve ride quality, align with factory geometry, and withstand long-term use. If you’re seeking a durable, easy-to-install suspension upgrade that redefines your truck’s stance while maintaining everyday drivability, this 6" GM Suspension Lift System is engineered for you.
