4 Inch Lift Kit | Rr Spring | Chevy/gmc C10/k10 C15/k15 Truck/half-ton Suburban (69-72)

Built for classic Chevy and GMC truck owners who want more ground clearance and tire-carrying capability, this 4-inch lift kit raises your C10/K10, C15/K15, or Suburban while preserving the smooth, planted feel of a factory-engineered suspension. Lifted leaf springs front and rear eliminate lift blocks for better geometry, and the included N3 shocks are valved specifically for your truck to deliver both on-road comfort and off-road control — all with room to run up to 35-inch tires.

Important notes

• This kit only fits vehicles equipped with 52-inch rear leaf springs. Confirm your rear spring size by measuring eyelet-to-eyelet before ordering.
• If your truck is equipped with a front sway bar, drop brackets (SKU 1019) are recommended to maintain proper suspension geometry.
• Proper backspacing is critical when running 35-inch tires — verify wheel offset with your installer to avoid tire or suspension contact.
