Review shared from ReadyLIFT 2-Inch SST Suspension Lift Kit (19-25 Sierra 1500 AT4)
2023 AT4 - AT4Upgrade
Installation Time: Afternoon
Looks Great!! Must do for a stock AT4
Upgraded the factory tires 2 sizes and installed this kit and gained about 3.75 more inches. Used the factory rims and the truck looks so sneaky modified that stock at4 drivers keep asking me what I did but it it isnt clearly modified to the regular eye. I love the look. Istall was quick. About 3.5 hours in my driveway with borrowed compression tool. Took it in for mount and balance on the tire and alignment and was off rolling for under 2k all in. Love it and made my truck what I wanted it to be. Did a bed cover too and its a huge win since it folds up the whole way but its hard (I can walk on it)

No problems with the install. The lift made my truck look like a whole new truck after wheels and tires were installed. Has an aggressive stance now. Ride quality feels the same if not better than before.

Good budget lift
I have lifted jeep in the past. This was my first truck to lift and it wasn't difficult at all. It took me 5-6 hours and rides great. The alignment after is a must. DO NOT SKIP IT!
