If you want to lift your front end to add larger wheels and tires, gain more ground clearance, stop your air dam from dragging on high objects, or compensate for the added weight of a custom bumper or winch MAXXStak Adjustable Front Leveling Kits are the solution. Perfect for off road use, and work and utility trucks.

The SuspensionMAXX MAXXStak 1.5 "/1.75”/2"/2.25"/2.5” Adjustable Front Leveling Kit is designed for the 2007-2019 Cadillac Escalade EXT and ESV, 2006-2013 Chevrolet Avalanche, 2007-2019 Chevrolet /GMC Silverado & Sierra 1500, and 2007-2019 Chevrolet/GMC Suburban, Tahoe & Yukon. The high quality kit provides the ultimate in adjustability and enables you to lift your front suspension by 1.5, 1.75, 2, 2.25 or 2.5 inches by inserting assorted shims that are specifically manufactured to combine with the strut mount for increased lift height. This adjustability allows you to obtain just the right amount of front lift for your needs – to match or exceed the height of the rear of the truck, as well as compensate for variables such as cab length, front end weight, desired snow plow height, etc.

To gain 1.5 inches of lift simply insert the solid steel MAXXStak spacers between the lower coil over struts and control arms then fasten with the supplied Grade 8 bolts and stover lock nuts. Lift can be further increased by ¼ inch increments, up to a maximum of 2.5 inches, by inserting a specified number of the provided Ultra High Density Polyurethane shims. These shims are specifically manufactured to combine with the strut mount for increased lift height. MAXXStak is compatible with steel or aluminum control arms and works with 2 wheel drive and 4 wheel drive vehicles. Installation takes approximately 2-2.5 hours using appropriate tools and is supported by the SuspensionMAXX Techical Support Program.

The MAXXStak Advanced Leveling Lift Kit for GMT900 based trucks and SUV’s is an economical alternative to a complex and expensive lift kit. The kit features leveling lift spacers that allow the original equipment shocks to be used, which maintains the comfort of the easy riding coil spring suspension used on GMT 900 vehicles. Retaining the stock shocks also reduces your cost. SuspensionMAXX leveling kits come complete with all necessary parts and hardware. No rude surprises learning additional components are needed – right when you are in the middle of doing the installation. MAXXStak is quickly and easily installed when using the correct tools and requires no cutting or drilling – making it reversible and ideal for leased vehicles.

Hi Adam,

Using our SMX-GM725 leveling kit works with the factory Strut. Our leveling kit doesn't overextend or change the strut travel. We do not preload the strut with a coil spring spacer. This maintains a smooth ride and doesn't require disassembly of your strut. The SMX-GM725 leveling kit simply lengthens the entire strut height.  This doesn't change shock or strut shaft travel.

Thanks for John and all the crew at Suspension Maxx for the fast and expert service at your shop, if I could pick 6 stars I would!! You guys and your products rock!!
Very pleased with the outcome and ride quality of this leveling kit. Here’s 2.5” in the front of my 2020 Silverado 1500 RST Z71. Thanks for making a quality product! 2 before photos and 4 are after.
I just want to say that this leveling is freakin' sweet, it rides like factory new. I installed it on my 2014 Chevrolet High Country 1500 4wd, and let me tell you it's awesome, perfectly level, I had no issues installing it. What an awesome product. I also want to thank the suspension maxx guys that answered all my questions. You guys rock!
