Factory shocks and coil springs can be retained - no shock replacement required
20"+ stock wheels and tires will also fit
MaxTrac does not recommend wheels wider than 9" or with less than 4.5" backspacing - doing so voids the manufacturer warranty

Features

One-piece ductile iron construction exceeds OEM strength standards - significantly more durable than cast alternatives
Delivers a true 4.5" front lift by replacing the factory steering knuckle - no drop brackets, spacers, or strut modifications needed
E-coated black finish provides long-term corrosion resistance
Includes DOT-approved extended brake lines to accommodate the lifted ride height - no binding or stretching of factory lines
100% bolt-on installation - no cutting, grinding, or welding required

Product Description

The MaxTrac 701345 is a pair of 4.5" front lift spindles with DOT-approved extended brake lines, engineered for 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 2WD trucks equipped with cast steel suspension arms. By replacing the factory steering knuckle with a taller one-piece ductile iron unit, the front ride height is raised a full 4.5" without modifying the struts, springs, or any other suspension components. Factory shocks and coil springs can be retained, and the installation is fully bolt-on with no cutting, grinding, or welding required.

The spindles are E-coated black for long-term corrosion protection and come with extended brake lines to safely accommodate the new ride height - preventing the binding and stretching that would occur with the factory-length lines at this lift height. The kit clears up to 33" tires on 17"+ wheels with 4¾" or less backspacing, and increases track width by 1" per side. A professional front-end alignment is required after installation.
