6 Inch Lift Kit | 52" RR Springs | Chevy/GMC C10/K10 Truck & SUV/K5 Blazer (77-91)

Elevate your GM classic with Rough Country’s 6 Inch Lift Kit for Chevy/GMC C10/K10 Truck & SUV/K5 Blazer (77-91) — a purpose-built upgrade that combines rugged appearance with real off-road capability. This bolt-on kit delivers a level, aggressive stance from front to rear while increasing ground clearance and confidence on tougher terrain.

• Front and rear lift with purpose-built components: Application-specific front lifted leaf springs paired with rear lift blocks and add-a-leafs ensure proper geometry and a smooth, controlled ride. An optional replacement rear lifted leaf spring setup offers a consistent rear lift without the need for lift blocks.
• Advanced shocks for daily driving and dirt roads: N3 Series shocks come standard, tuned for your exact application. With a 10-stage variable valving system, high-pressure nitrogen charge, and a heavy-duty 54mm body with an 18mm piston rod, these shocks balance on-road comfort with off-road capability.
• Room for bigger tires without sacrifice: The 6" lift provides ample clearance to run up to a 37" tall tire with proper backspacing, giving your ride the bold, capable stance you want while preserving steering control.
• Corrected steering geometry for confident handling: A raised steering arm is included to maintain precise steering and predictable handling after the lift, so you don’t have to compromise drivability for altitude.
• Brake line and geometry preserved: Brake line brackets and thoughtfully engineered geometry components keep braking feel consistent and predictable, even when you’re crawling over rough obstacles.
• Bolt-on simplicity with lasting support: Designed for straightforward installation, this kit offers a robust upgrade that you can trust for the long haul, backed by Rough Country’s Limited Lifetime Warranty.

The 6 Inch Lift Kit is crafted for enthusiasts who want more capability without sacrificing ride quality. It’s ideal for classic GM trucks and SUVs (77-91) that see trail duty, overland weekends, or simply want a head-turning, tough look on the street. The combination of front lifted leaf springs, rear geometry options, and N3 shocks delivers a balanced ride that feels closer to factory when cruising and confident when you head off the pavement.

Why this kit stands out

Many lift solutions focus solely on height; this kit emphasizes real-world performance. You’ll notice:

• Improved ground clearance for rocky roads and uneven terrain, without trampling ride comfort.
• Strategic shock tuning that reduces body roll and keeps tires planted under braking and cornering.
• Long-term reliability with a durable 54mm shock body and nitrogen-charged internals designed for repeated off-road use.
• Preserved steering feel and precise control thanks to the raised steering arm and properly adjusted geometry.

For those who want to push their build further, the option to replace rear lift components with lifted leaf springs offers an alternative that maintains a consistent rear height and simplifies maintenance over time.

Who should consider this lift kit

If you own a Chevy/GMC C10/K10, or a K5 Blazer from 1977–1991 and crave a more commanding presence, this kit is a compelling choice. It suits daily drivers who want weekend trail capability, weekend warriors who test rough terrain, and builders aiming for a bold, rugged silhouette without compromising reliability.

Installation and care

Expect a straightforward bolt-on process with the right tools and basic mechanical skills. After installation, check key fasteners and alignment to ensure peak performance. Routine inspection of shocks, springs, and brackets will help you enjoy steady handling and long-lasting performance across adventures.
