GMC 1500 Sierra Denali 2015 – 2018

Product is excellent. On my lifted 2016 Sierra Denali the installation was a bit more difficult than what is shown in most of the videos due to having to pull the top spring bracket off for placement of the RAS base mount. This base is different on the 2611 kit than what is in most of the pictures because the Denali has a ride height sensor that needs to be avoided and sits close to the leaf springs. No fault of the product, just more than I expected to take on. Fully installed the bed is raised and additional 1.5" using the black spacer. The drive unloaded seems noticeably more connected to the road.

I like the idea. I have installed the 2611 on my 2018 GMC 1500 Sierra Denali. While not technically hard, it's probably 100x harder than typical RAS systems because in order to accommodate the Magnaride hardware, the typical RAS leaf-spring bracket is replaced by a flat bracket which must be installed on top of the leaf springs; and this requires dropping the axle. Not only that, when I had everything back together, my truck pulled to the left a bit. I was able to loosen the axle U-bolts and adjust it...and got it back in line. But to be sure, the axle has enough wiggle-room so that your alignment can be off after installation. As to performance, it raised my rear a bit (but I've got it set mid-range tension) but I haven't noticed any degradation in ride over 500 miles. I think I may add a 2" leveling kit to the front. I bought this to help with rear sag when towing an Airstream; but I haven't really put it to the test yet. Like I said, I like the idea. Pretty cool. But buyer beware: the "easy-as-pie" general instructions for RAS do not apply to the 2611.

Didn't work for me. My 2017 GMC Sierra Denali 1500 would squat 2.5in before install when connecting small 2 horse trailer and after install it still squats 2.5in. It raised the rear of the truck .75in, but squats 2.5in when trailer is hooked up. Very disappointed. Wish I would have skipped the Road Active Suspension install & installed Air Lift air bags instead.
