Silverado 1500 & Sierra 1500 Lift Kits and Suspension

Half-ton GM trucks run a coilover strut up front. That's where the ride is won or lost. A spacer on top of the factory strut gets you height and nothing else. It loads a shock that was never valved for it and pushes the ball joints and CV axles to steeper angles. We don't install them.

What we do install:

• Bilstein 5100 and 6112 for a leveled daily driver that still rides right
• ICON and FOX coilover systems for trucks that see real dirt
• BDS lift kits when you want 4 to 6 inches and room for 35s

Trail Boss and AT4 trucks already sit about 2 inches up from the factory. They need parts built for that starting height, not a standard 1500 kit.

See how it comes together: a 2024 Sierra 1500 AT4 on a BDS lift with FOX 2.5s and a 2018 Silverado 1500 on Bilstein 6112s. More on the Chevy and GMC builds page.

Silverado & Sierra 2500HD / 3500HD Suspension

HD trucks are a different animal. More weight over the front axle, torsion bars instead of coils, and most of them tow. Cranking the torsion keys is the cheap way to level one. It's also why so many leveled HDs ride harsh and go through front-end parts.

We set HD trucks up around the work they do. How much you tow. What rides in the bed. How much highway versus dirt. Then we match shocks, control arms, steering support, and rear airbags to that, using Bilstein, FOX, ICON, and BDS.

Wheels, Tires, Lighting and Armor

Suspension first, then wheels and tires. Wheel offset decides whether a tire clears or rubs, so we spec the wheel and tire to the lift, not the other way around. Method Race Wheels and Toyo tires are our go-to. Baja Designs for lighting. Bumpers, sliders, and skid plates made for your truck, not universal-fit.

Chevy & GMC Lift Kit Questions

What size tires fit a leveled Silverado or Sierra 1500?

Most leveled 1500s clear a 33-inch tire. 35s usually take a 4-inch or taller lift, the right wheel offset, and sometimes trimming. Tell us your year, trim, and wheel and we'll tell you what fits before you buy anything.

Do you install spacer lifts or leveling pucks?

No. A spacer adds height without adding travel or control, and it speeds up wear on ball joints and CV axles. We level trucks with ride-height-adjustable shocks or coilovers so the geometry stays right.

Can I level a 2500HD by turning up the torsion bars?

You can, and it's the cheapest way to do it. It also makes the truck ride harsh and wears front-end parts faster. Matched shocks and upper control arms cost more up front and less over the life of the truck.

Will a lift kit void my GM warranty?

Not the whole warranty. Under the Magnuson-Moss Warranty Act, a dealer has to show the aftermarket part caused the failure before denying a claim. Our warranty guide covers the details.

Do you offer financing?

Yes. 0% for up to 6 months on approved credit through Synchrony, plus an all-credit option through American First Finance. Both cover parts and install.
