2007 Chevy Silverado Buildup - McGaughy's 7-Inch Lift Kit

After

A pillar in the lowered truck world, McGaughy's is no stranger to altering suspensions and making a truck look, handle, and even ride better. So, when we heard they were designing a new lift kit, we couldn't wait to check it out. Available for GM 1/2-ton and 3/4-ton trucks, along with SUVs, the new McGaughy's lift kits come laser cut and machined, powdercoated in a metallic silver for good looks and long durability, and CAD-designed lift spindles (with a lifetime manufacturer defect warranty) are included. Increasing the ride height by seven inches, the new lift will help Silverado and Sierra's clear 35-inch tires easily, and with lower A-frame support rods and compression struts, the kit is extra tough for real off-road use.

A nice perk to this lift kit's design is the lack of cutting or grinding on the front differential-the only cutting is the lower control arm frame mount and new filler plates are included for added strength, along with the lower strut extensions, which don't require you to disassemble the factory strut.

We took a stock '07 Chevy Silverado 1500 4WD and in just over five hours, it was ridin' high and lookin' great. Check out the story to see how the kit was installed.

With the new 7-inch McGaughy's lift kit unpacked, we got to take a look at the burly lower control arm brackets, lift spindles, strut extensions, compression struts, add-a-leaf, lift blocks, and new shocks for the rear.

After placing the truck on the shop lift, we removed the wheels/tires, then the caliper was unbolted and hung from the frame with a bungee cord, and an impact was used to bust the CV axle nut loose.

Next up, the three bolts holding the wheel bearing hub to the spindle were removed, the hub set aside, each front CV axle removed, and the upper and lower ball joint nuts removed so the spindle could be pulled free.

A couple zips with the impact gun was all it took to remove the lower control arm nuts and bolts and then the lower control arm was pulled from the frame mounts.

A tape measure and flat screwdriver was used to make the exact cut locations.

Using a tranny jack for support, the differential mounting bolts were removed and the front differential was lowered out of the way. This gave us access to the inside of the A-arm frame mount.

All it took was a few minutes with the Miller MIG welder and the plate was good to go. Next, a 1/4-inch on each lower A-arm pocket was removed thanks to a grinder. This provides extra clearance for the diff drop down brackets.

Keeping the CV axle geometry correct, McGaughy's included these differential drop down brackets to space the differential down. All it took was a couple of bolts to secure them in place.
