Complete 7" Suspension Lift with FOX 2.0 Performance Series

Take your 2007–2016 Chevy Silverado or GMC Sierra 1500 2WD to the next level with the MaxTrac K881375F suspension lift kit. Designed specifically for trucks with cast steel control arms, this package delivers 7" front / 5" rear lift using MaxTrac lift spindles, adjustable FOX 2.0 Performance Series coilovers, extended brake lines, rear lift blocks, U-bolts, and matching FOX rear shocks. Built to clear up to 35" x 12.50" tires, it's a complete setup for a taller, more aggressive truck.

Key Features

4.5" Front Lift Spindles

Heavy-duty MaxTrac lift spindles provide 4.5" of front lift and include extended brake lines to accommodate the increased suspension height.

Adjustable FOX 2.0 Front Coilovers

5" Rear Lift Blocks & U-Bolts

Matched rear lift blocks and U-bolts raise the rear suspension 5" for a balanced lifted stance.

FOX 2.0 Performance Series Rear Shocks

Includes two FOX rear shocks designed to provide consistent damping and suspension control.
