This truck is plenty powerful on its own with the Duramax Diesel. Tons of torque, a great ride and built tougher than any other truck out there. Lots of room inside. I had the full Banks system added over time (chip, exhaust, Six-Gun and Speed Loader) and this truck is faster, stronger and better than I could have imagined. I get a combined 18MPG and I put the miles on this beast in all the worst driving conditions. My acceleration is amazing. You CANNOT go wrong with the Duramax diesel and the Alison transmission. It will stand up to anything you throw at it.
Bullet-proof engine, tons of torque, On Star. Lots of room, able to haul anything.
