Rated 5 out of 5
Walter Hawes –
7 inches on the 2500HD and it sits perfect with 37s. Skyjacker’s components are solid. no squeaks or issues after months of use.

My ’17 Sierra 2500HD needed a serious lift to match the way I wanted it to look and perform. The Skyjacker 7-inch kit delivered beyond my expectations. It sits tall, looks tough, and the ride quality is far better than I feared for a 7-inch lift on a heavy duty. Fitted 37s with no trimming needed. My installer called it one of the cleanest fitting kits he’s worked with. Whether you’re doing it for looks or off-road capability, this kit covers both.

My 2500HD needed real clearance for the 37s I wanted to run and this 7-inch Skyjacker kit delivered exactly that. Components felt heavy-duty right out of the box, nothing flimsy about the brackets or control arms. Took my shop about a day and a half with the front differential drop included. Handling on the highway is still stable and predictable, no wandering at speed despite the height increase. This truck tows a gooseneck regularly and the suspension hasn’t shown any signs of sagging. Excellent kit for a heavy-duty truck.
