2015 GMC Sierra Belltech 4" Lift

Lannie · October 5, 2021

I have not seen any reviews other than one youtube video of a 2019 Silverado getting this kit. I ordered it for $799 and it comes with up to 4" lift struts, shocks, diff drop and upper control arms.

While I was waiting for the lift kit to be made and shipped I ordered everything I could so while I had it all apart, everything would be new. It took them 2 months to get me the kit but I think they were dealing with the same shortages of supplies as everyone else. I received the kit and it came with everything needed and no missing pieces.

It took me 18 hours of lying on my concrete garage floor doing it all myself. (used new 6 ton jack stands and my 3 ton jack to be safe) I replaced the following items while doing this kit:

Lower Ball joints (Moog for Aluminum arm)

Sway bar links

Torsion bar mounts

Tie rod ends

Rotors

Caliper slide pins

Ceramic brake pads

I dreaded doing the strut springs but with the proper compressor tools I bought it was easy. The much stronger compressor kit was safer and easy. You can choose to use all 4 rings on the strut for 4" of lift or fewer and drop .5" each ring. The diff drop was not really hard. The instructions say to loosen the 4 bolts and replace one at a time. You cant due to the flange around the frame where the spacer goes. You have to remove both front bolts and loosen the back ones in order to lower the diff far enough to get the spacer in past the flange then tighten up the front and move to the rear ones.

The lift was 1/4" taller in the front when it was all done. However I had a bad camber where the tires were on their edge and not flat. Once the alignment was done and the tires square on the ground it is perfectly level. Within 1/16 of an inch!

With everything new under the truck I was shocked at how much better it drove. Stiff, firm but still smooth. I never realized how sloppy it had become. 190K miles on this thing. It had a 1.5" level spacer since 70K. The balls joint really were not bad considering having that many miles with a level.

Anyway, the ride height is exactly what I wanted. Tires are Toyo Open Country 305/55R20 R/T Hybrids.

Anyone looking to get a complete kit for a great price, I am very happy with this setup. I wanted Bilstein all around but getting the struts and shocks included in this kit was worth the price.

Thoughts???

The result speaks for itself.
A great result from your hard work, nice job!

It was a lot of work. Nothing real difficult but slow and steady was my plan. Don't get hurt and don't break anything. lol

Thanks for the info. I have a new to me 2015 Silverado with 128k miles that needs new shocks, so my search has led me to lift/level options that include the shocks. That is basically four options: Bilstein, Eibach, Rough Country and this Belltech kit. I talked to Belltech on the phone, and was impressed with the knowledge of the tech on how these struts were developed for the GM trucks. Can you post more angles/pictures of your truck with this lift? Do you think you could fit bigger tires? Are those 305's bigger than a 33/12.5?

Bigger, yes, but not as wide. See here:

I will get some more pics for you. I can easily fit 34" tires with this lift. Probably could squeak by with some 35s. I could easily go with 13" wide since I have 1.5" spacers. The 305s look small now. lol
