Maxracing 2.5" Front+ 2.5" Rear Lift Kit for Tahoe Suburban Yukon Avalanche | 2007-2020 Tahoe Suburban Yukon, 2007-2013 Avalanche 1500 4WD/2WD, CNC Machined, Forged Aircraft Aluminum, Easy Bolt-on Design

Excellent leveling kit. I installed these on a 2018 Silverado. I'm running 33x12.5R22 mud tires with Yukon Denali 22in wheels (+24 offset, 5.94 backspacing) and no rub. Before the alignment the tires slightly rubbed the sway bar at full lock and didn't rub at all against the fender liner. After the alignment with the caster angle adjusted, there was no rub at all. Be sure to tell the shop to adjust the caster, not all shops will do this without being asked. (Even though they should without being asked) My shop specializes in off-road trucks and they set my caster at +3.7°, which feels about perfect. However, I do have larger upper control arms, so your angle may be different if you keep the factory uppers. I installed larger upper control arms made for 2in to 4in of lift. With the larger control arms, the shop that did the alignment said he nearly maxed out the adjustment on caster, but it was set where it needed to be. He said the factory control arms probably would have adjusted to the correct caster too, but I personally recommend upper control arms since the factory stamped steel upper control arms and factory upper ball joint can fail over time with the lift. There's a lot of geometry change going on and the upper ball joint just can't articulate enough at full extension. Which means it can snap if the wheel extends hard enough. These 2in leveling blocks leveled the truck perfectly flat with no change in the rear. 2.5in is the max that can be added to the front without lowering the transfer case as well as other mods. So, 2in is a good comfortable lift height to simply level the truck with minimal other mods. But again, I do recommend upper control arms. I also recommend sway bar end links since the factory ones had seized and needed to be cut off. (Also, aftermarket sway bar end links improved the smoothness of the suspension so much, and they're not expensive, so go ahead and order them). I used a 4in cutoff saw, and still had to hit the factory ones with a blowtorch to melt the plastic enough to get the bolt out of it. They were trash. The replacement went in without issue. Install was easy. 1. Remove the 21mm nut on the tie rod, tap out and push aside. 2. Remove (or cut off) the sway bar end links. 3. Remove both lower bolts on the strut. Use a pry bar under the strut and pry against the lower control arm to slide the spacer in, then use a pry bar in the space between the upper control arm and the bottom of the spring to push the bottom of the strut inward toward the holes to align them. (With the spacers the bottom of the strut will want to push out toward you, so you'll need to pry it back to slot the bolt in) It takes a little work and a bit of luck to get the first bolt hole lined up. A second set of hands would have gone a long way to make it easier. 4. Insert bolts/washers/nut. Torque the hell out of them. Then retorque after 20 miles and 100 miles. Since you won't be removing the wheel hub assembly, on 4wd the CV axle will be in the way of one of the bolts. Just insert it from the bottom. The bolt cleared on mine but it was close. If needed cut the bolt a smidge. 5. Reinstall the sway bar end links, reinstall 21mm nut on tie rod (you may need a 10mm wrench to keep the ball joint from spinning. I used an impact gun and didn't need a wrench.) An additional note on clearance, I'm installing 2in wheel spacers, so I'll need to do the NorCal mod from rough country to prevent rubbing on the rear of the fender liner. If your wheels have a large offset they'll rub some with 33s. (Actually diameter of my tires is 32.75in) Hope that helps! Great product, great price.

The rear lift kit would not work. 2026 GMC has the monoleaf springs. No good

Very easy to install. 1.5 hours . My 2021 GMC 1500 AT4 now has 8 inches of clearance both front and rear . Good product and good price.

that the rear spacer is 3" and it lift truck 3 1/2 in"

Simple and effective. I installed this product in a matter of minutes. My truck looks great and I love the leveled look!
