Every component down to our shock extensions are precision machined, zinc coated. We include these extensions with our kit ensuring your shocks are not over extended. Longer shock studs are included to allow you to fasten your factory wire harness in place. Last but not least, the MAXX travel control arms, designed to give you increased ride height while maintaining proper suspension geometry and travel. Some may ask why changing the control arms are necessary. We have designed our control arms to compliment the leveled ride height. The factory control arms are flat across all three mounting points and as you lift your truck, the ball joint angle is increased.  At the same time the upper control arm looses clearance to the suspension limiting bump stop that is located under the front of the upper A-arm.  Our hand fabricated, TIG welded control arms feature improved clearance to this bump stop. The MAXX travel what will allow you to lift your truck up to 3” from stock while maintaining a satisfactory ride.  Our control arms are had fabricated from 0.188 wall 1-3/4” tubing, powder-coated finish and utilize greaseable MOOG ball joints for trouble free operation for thousands of miles.  If you desire the best kit for your HD Silverado or Sierra and you value quality American made craftsmanship, look no further than SuspensionMAXX for the most complete 3 inch leveling kit on the market.

Product Reviews

Ok guys I installed the Suspension Maxx Stage 1 kit with the fix shocks on my 2018 GMC 2500HD and I have to say it’s the best decision I have made. I put 35x12.50x20’s on it with no rubbing or trimming what so ever. Before and after pictures.
Okay her is my updated review I bought stage 1 kit last year and just put this kit on last month I was going to install myself but work got in my way and then covid, first off this is a must buy kit it looks great and rides better than factory I do wish I bought kit with shocks as I did have to replace my front ones I have a 19 duramax 3500hd with30k miles, hands down the kit is very nice looks great Tires I did bf ko2 all terrain 35x12-18 and did wheels with 18mm offset fits almost perfect I had to do a trim work but nothing major and you would never be able to tell. I have 1/2 in sage in the rear and maybe thinking about doing the 1in block kit. This kit is a great way to lift your truck customer service is excellent and kit is great don’t cheap out buy just no name keys buy this kit and buy the stage 2 with shocks.
Well I have had this leveling kit on my 2014 GMC Sierra 2500HD for about a month now!! And this is hands down the BEST leveling kit I have ever purchased!! The parts are high quality and made here in the USA!! I would Definitely recommend this kit to anybody!! My truck rides better than factory without upgrading the shocks!! Easy 5 stars!! And the customer service is excellent!! If your thinking about buying this kit don’t worry just do it you won’t be upset!!!
Dont waste time on other leveling kits.. this product is high end quality.. worth every penny and made here in the states.. customer service was amazing.. thank you guys for putting out the best possible level kit..
Hands down but this kit in any stage 1,2, or 3 If could give this kit and all the guys in the shop more stars I would the kit is over built directions are spot on and Larry is awesome the customer service is over the top and they care about there products and the service I looked at all and I mean all of the lifts and key lifts out there available for my 2019 Chevy 1ton crew duramax and landed on this one and I’m glad I did. Now I do have to say I haven’t installed it yet but just from talking to a couple of guys and Larry at the shop I’m glad this is the kit I bought and have zero worries about any problems with this kit if you have any doubts about buying this kit just call them. On my truck I want to run 35in tires and keep the same or better ride and I’m sure it will ride great. I will come back and update my review after install and drive for some time but all you out there do your research and then come back here and order the money for the kit is worth it being built but hand in the USA but a company that cares.
