Put these on my 2021 GMC Sierra 1500 AT4 with 3.0L Diesel, 18” wheels and 275/65r18 Duratracs. Everything went on easily and without issue. Also installed some new Upper Control Arms to fix any issue with the ball joint angles. The ride is definitely stiffer than the stock R@nchos but so much better. No bouncing for 100 yards after a dip, no swaying through corners, no rear end bounce or walk. I have the front set to the highest 1.1” and it did make the truck more level, however it’s still 3/4” to 7/8” from being perfectly level. I contacted the UCA manufacturer about adding an additional spacer and was advised against it. I do think I will try some 285/70 or even 285/75 tires. The width should still be ok in clearing the UCA and there should only be minimal run, if any.
Are the Bilstein 5100’s worth it? Yes. Definitely yes.

2021 GMC AT4, stock Rancho suspension very poor, a lot of roll and sway thru minor turns, my previous cars were BMW M4. I had expected a big change in handling but I started to regret buying a new truck, I should have purchased a used beater and stayed in a car. Since installing front coil overs and rear shock from Bilstein the ride and handling have improved 100%, Drives like a new truck should. I would recommend installing Bilstein on your ride ASAP

After tons of research for new shocks for my 2021 GMC Sierra 1500 AT4, I decided on this Bilstein set for front and rear. Couldn’t be happier. So much of an improvement over the stock Rancho’s. A firm but nice ride. After all is said and done and truck has settled- i added a little over an 1” to the stock 2” lift on the front and truck is very close to level. All geometry and angles of UCA’s is good. Shipping was very fast, although box did come a little ripped and damaged. Probably UPS fault and not Bilsteinlifts.com I looked at basically every shock brand and compared reviews and specs. Felt this was absolutely the best choice for my AT4. Extremely satisfied and pleased with purchase and performance.

I have a 2020 GMC 1500 AT4 6.2L. I had these installed at their highest setting and now my tires rub. This company’s description is misleading. It read’s 2.75” adjustment. The AT4 comes with a 1.5” lift. So I thought these would make my truck sit higher. It definitely does not sit higher. My tires rub now. Now I have to install a leveling kit. It’s my fault I guess but still, I want people to know so they don’t make the same thousand dollar mistake I just made. I’ll never purchase again.

Snag a set of these about a month ago now. Immediately of install of the rear felt a big difference in the ride. Took a few weeks to get it on the lift to install the front, and about an hour later took it for a test ride. Everything fit the way it should and the truck ride is great. The wife even noticed within the 1st mile of her 1st trip out with me. I set the front to the highest setting. It almost made it level. The truck looks better and the drive is improved. Should have done this sooner.

Installed on my 2019 Sierra AT4.
The front Ranchos were weeping but still had some life left. The rears were completely worn out. The ride has significantly improved with the extra dampening from the Bilsteins. If you are trying to find an affordable replacement shock/strut, go with these!
Company was quick to ship and fast to respond when a package arrived damaged.
Affirm was easy to work with and payments were low.

Bought front and rear 5100’s for 2021 AT4. Fit and functionality are top notch. Must have upgrade for your truck.
