DESCRIPTION
This 2023 GMC Yukon XL Denali Ultimate is an absolute monster of a full-size SUV. While a standard Denali Ultimate is already the pinnacle of GM luxury, the addition of a Lingenfelter Supercharger takes this vehicle into elite, high-performance territory. Combined with low mileage (34,113 miles) and an extended XL wheelbase, this is a rare find that perfectly balances executive-class luxury, advanced technology, and massive power. Here is a breakdown of what makes this specific build so unique and capable: The X-Factor: Lingenfelter Supercharger In its factory form, the Yukon Denali Ultimate comes equipped with a 6.2L V8 engine producing a healthy 420 horsepower and 460 lb-ft of torque. The Upgrade: Lingenfelter Performance Engineering is legendary for GM tuning. Their supercharger package (typically utilizing a TVS2650 Magnuson supercharger) pushes the 6.2L V8 to an estimated 650 to 700 horsepower and similar torque numbers. What it means on the road: It transforms a heavy, 3-row family hauler into something with sports-car-rivaling straight-line acceleration. The power delivery is smooth, linear, and immediate, making highway passing and heavy towing effortless. Get a test drive today!
