The AT4 trim adds offroad / sporty features: 2 factory lift, offroad suspension with Rancho monotube shocks, skid plates, special interior upholstery and badging for the AT4. The 6.2L V8 (RPOL87) in the 2025 Sierra 1500 is rated at 420hp and 460lbft of torque. On smoother roads and highways, the Sierra carries itself quite well. One review noted that for the 2025 model, the independent front suspension (and optional adaptive systems) help the ride feel more composed than you might expect in a fullsize truck.
