GMC Sierra 1500 Suspension Guide: Lift Kits and Shocks

If you drive a Sierra 1500 and you're staring at the tiny gap between your tires and the fender, or you just want the truck to sit level instead of nose-down from the factory rake, suspension is where you start. This guide breaks down what's actually in stock for the Sierra 1500 right now: leveling kits, full lift kits, shocks-only upgrades, the control arms that support bigger lifts, and a load-support option for towing.

RideBuildList earns commissions from some retailer links.

This is a pick-one guide, not a shopping list. You're choosing the one option that matches what you're actually trying to do, not stacking all of them into a single build.

Leveling kits: correct the rake, keep the ride

Most half-ton trucks leave the factory with the front sitting an inch or two lower than the rear. A leveling kit closes that gap so the truck sits level and clears a bigger tire up front. These are the cheapest way into this category and usually the easiest install.

On the low end, the Rough Country 2 Inch Leveling Kit | Chevy/GMC Sierra/Silverado 1500 (19-25) 2WD/4WD gets you a basic 2 inch correction. The ReadyLift ReadyLift 19-25 Silverado/Sierra 1500 2WD/4WD 1.5" Leveling Kit (66-39150) does a smaller 1.5 inch lift if you want a more subtle look. Step up to the Zone Offroad 2 Inch Leveling Kit | Chevy Silverado or GMC Sierra 1500 (19-26) for another 2 inch option from a different brand, or the Cognito Motorsports Cognito 3-Inch Standard Leveling Kit [19-25 Silverado/Sierra 1500 2WD/4WD] if you'd rather run a kit built around a full 3 inch correction instead of a simple spacer.

If you run an AT4, the Rough Country 1.75 Inch Leveling Kit | Forged Alum UCA | AT4 | GMC Sierra 1500 (2019-2025 & Classic) is built specifically for that trim and pairs a 1.75 inch lift with forged aluminum upper control arms instead of just a spacer. That AT4-only fitment is listed on the part itself, not something we're guessing at, so check your trim badge before you buy.

Lift kits: bigger tires, more travel

A lift kit goes further than a leveling kit. It usually changes the shocks, springs and control arms together, and it's what you need if you're planning on 33s, 35s or bigger and want the suspension geometry to still work correctly at that height.

The Rough Country Rough Country 7 Inch Lift Kit w/ M1 Struts & M1 Shocks for 2014-2018 Chevy Silverado 1500 / GMC Sierra 1500 is a 7 inch kit built around M1 struts and shocks, though its fitment on file covers the 2014-2018 trucks with the 5.3L or 6.2L V8, so check your year and engine before ordering. For a more moderate lift, the Zone Offroad 4 Inch Lift Kit | GMC Sierra 1500 Denali (19-24) 4WD is a 4 inch kit built for the Denali trim. The BDS Suspension 3.5 Inch Lift Kit | FOX Coil-Over | Chevy Silverado or GMC Sierra 1500 (25-26) 4WD is a 3.5 inch kit with FOX coil-overs built for the newest trucks. On the higher end, the ICON Vehicle Dynamics ICON 2019-2026 Chevrolet Silverado 1500/GMC Sierra 1500, 1.5-3.5" Lift, Stage 2 Suspension System, Tubular is a tubular Stage 2 system covering a 1.5 to 3.5 inch range, and the Cognito Motorsports Cognito 8-Inch Elite Billet UCA Lift Kit with Fox 2.5 Elite Performance Series Shocks for 19-25 Silverado/Sierra 1500 2WD/ 4WD, Including AT4, AT4X, Trail Boss, & ZR2 sits at the top of the catalog for this platform, an 8 inch billet kit built specifically for AT4, AT4X, Trail Boss and ZR2 trucks with FOX 2.5 Elite shocks.

The catalog doesn't publish a horsepower or towing figure for any of these kits, because that isn't what a suspension kit changes. What changes is ride height, wheel travel and how the truck sits under a load. Judge these on lift height and what's actually in the box, not a performance number that doesn't exist for this category.

Shocks only, no lift

Not everyone wants to change ride height. If your Sierra rides at stock height but you want better damping, especially for towing or rough roads, a direct shock swap is the move. The Bilstein 0-2.5" Front Pair Bilstein 5100 Adjustable Struts , 2019-26 Silverado Sierra 1500 is an adjustable strut pair that bolts in at stock height with a small range up to 2.5 inches if you want it. The FOX Shocks FOX® 2.0 Performance Front Shock Individual for 2019-2026 Silverado Sierra 1500 is a single front performance shock built for the same stock-height application.

Control arms: the part that makes a big lift work right

Once you get past roughly 3 inches of lift, stock control arms start running out of range and the suspension geometry gets worse instead of better. That's the problem a billet or forged upper control arm fixes. The Cognito Motorsports Cognito Billet Upper Control Arm Kit [19-26 Silverado/Sierra 1500 2WD/4WD & 21-26 GM SUV] is a billet upper control arm kit built to pair with a bigger lift and restore proper geometry at that height.

Towing and load support

A leveling kit or a lift kit isn't the right fix if your actual problem is rear sag under a heavy trailer or a loaded bed. For that, the Timbren Timbren Rear SES Suspension Kit for 2019+ Chevy Silverado 1500 / GMC Sierra 1500 adds load-bearing support in the rear without changing your unloaded ride height, which is a different job than anything above and shouldn't be confused with a leveling kit.

What to check before you buy

• Confirm your trim first. The Rough Country 1.75 inch kit and the Cognito 8 inch Elite kit above are both built specifically for AT4 (and AT4X, Trail Boss, ZR2 on the Cognito kit). A kit built for one trim isn't guaranteed to bolt to another.
• Confirm your year and drivetrain. Several of these kits are cataloged for a specific year range and 2WD or 4WD, and at least one only lists certain engines.
• Budget for an alignment. Every kit in this category changes suspension geometry to some degree, and skipping the alignment afterward is the single fastest way to chew through a set of tires.
• Ask your installer or the kit maker about your state's lift height and headlight aim rules before you commit to anything past a basic leveling kit. Some states cap bumper height or regulate headlight aim after a lift. That's a legal question for your state's DMV or an attorney, not something we can state as fact here.

One honest note on this catalog: install difficulty and install time are listed the same way for nearly every suspension part on this platform right now, whether it's a basic leveling kit or a top-tier coilover lift system. That reads like a placeholder in the data rather than a real per-kit estimate, so don't treat the listed install time as gospel for anything past a basic bolt-on kit. Talk to a shop for real hours on the bigger builds.
