6 Inch Lift Kit | Chevy/GMC C10/K10 Truck & SUV/K5 Blazer 4WD (1977-1991)

Elevate your GM pickup with the 6 Inch Lift Kit for Chevy/GMC C10/K10 Truck & SUV/K5 Blazer 4WD (1977-1991). This bolt-on system lifts the stance from front to rear, delivering a bold profile while increasing ground clearance and off-road readiness without sacrificing everyday ride quality.

What makes this kit uniquely capable — designed as a cohesive suspension upgrade, it uses application-specific front lifted leaf springs in combination with rear lift blocks, add-a-leafs, and brake line brackets to preserve geometry and maintain a factory-like ride after install. For a cleaner rear suspension, you can opt for the version with replacement rear lifted leaf springs that removes lift blocks entirely.

• Premium front and rear geometry: Front lifted leaf springs paired with carefully selected rear components keep axle alignment consistent and braking lines properly routed, preserving predictable handling.
• Improved steering control: A raised steering arm is included to correct steering geometry after the lift, delivering tighter, more responsive on-road feel and stable off-road control.
• Rugged, tunable shocks: N3 series shocks come standard with exact application valving, offering a 10-stage damping range, a high-pressure nitrogen charge, a 54mm shock body, and an 18mm piston rod for durability and responsive control in varied terrain.
• Space for bigger tires: With 6" of lift, you can fit up to 37" tall tires with proper backspacing, unlocking aggressive looks and improved traction on rough trails.
• Warranty you can trust: This kit is backed by Rough Country's Limited Lifetime Warranty for long-term peace of mind on both street and trail.

Who benefits most — classic GM truck and SUV owners who crave an elevated stance and real off-road capability. If you drive a C10, K10, or K5 Blazer 4WD from 1977–1991 and want to conquer rough roads, rutted trails, or sandy overland routes, this 6" lift kit is engineered for you.

Practical notes and use cases — - Daily drivers will notice a more commanding road presence while retaining comfortable highway manners thanks to tuned leaf springs and N3 shocks. - Trail rigs gain improved approach and departure angles, better clearance under rock ledges, and room for larger tires that bite on loose surfaces. - Overlanders can configure wheel-and-tire packages for higher clearance without compromising load handling or braking responses.

Compatibility — fits 1977–1991 GM 4WD trucks and SUVs, including C10, C/K, K10 pickup lines, and K5 Blazer 4WD models. For a fully integrated rear suspension, choose the variant with rear lifted leaf springs.

Upgrade with confidence. The Rough Country 6 Inch Lift Kit combines engineered ride quality, robust durability, and a bold aesthetic that transforms your classic GM truck into a purpose-built machine for both street and trail.
