6 Inch Lift Kit | 52 Inch Rear Springs | Chevy/gmc C10/k10 Truck & Suv/k5 Blazer (73-76)

Built for classic Chevy and GMC truck owners who want aggressive lift without compromising geometry — this 6-inch suspension lift kit pairs application-specific front and rear leaf springs with premium N3 shocks to deliver a level stance, better ground clearance, and room for up to 37-inch tires. The included raised steering arm corrects caster geometry after the lift, so your truck handles tight and true.

What's included

• N3 Shock Pair (Front) — Twin nitrogen-charged shocks with application-valved 10-stage variable dampening and 54mm bodies, tuned for balanced on-road comfort and off-road control on lifted suspension.
• N3 Shock Pair (Rear) — Matched rear shocks engineered for the same responsive performance and durability as the front pair.
• 6-Inch Front Leaf Spring (Qty 2) — Lifted springs cut to deliver the full 6 inches of height while maintaining geometry and ride quality without rear lift blocks.
• 6-Inch Rear Leaf Spring (Qty 2) — Application-specific rear springs engineered for a level stance and consistent suspension geometry across the axles.
• Raised Steering Arm — Corrects steering geometry and caster angle after the lift for precise handling and improved alignment characteristics.
• Brake Line Relocation Brackets — Keep brake lines properly positioned throughout suspension travel for safety and uninterrupted braking performance.
• U-Bolt Kit — Heavy-duty fasteners for secure leaf-spring-to-axle mounting.
• Bushing Kit — Reinforced bushings for durable suspension articulation and reduced deflection under load.
• Installation Hardware — All fasteners, shims, and brackets required for a complete bolt-on installation.

Important notes

• This kit fits only vehicles with 52-inch rear leaf springs. Confirm your rear spring size by measuring eyelet-to-eyelet before purchase.
• If your truck is equipped with a factory front sway bar, drop brackets (SKU 1019) are recommended to maintain suspension clearance and handling.
• Vehicles with factory quad-shock setups (two shocks per front side) will use a single aftermarket shock per side with this kit.
• Proper backspacing on wheels is required to safely run the full 37-inch tire clearance; work with Road Runner to verify wheel offset before purchase.

Why customers pick this at Road Runner

• Raised steering arm included — corrects caster geometry right out of the box, eliminating the need for a separate realignment purchase.
