Hello,

My name is Stephen, I own a 2000 sls gmc jimmy with the 4.3l vortec. I'm just getting ready for college and want to put a little more horsepower in it. I have the biggest sizes tires on it i can without them rubbing. They are grabber AT2, Great tire! It is not a zr2.
I want it to be able to tow a trailer with the max two sled or four wheelers. Maybe a car or to on the trailer. I'm open to any suggestions and want to learn a lot more than I know about the best parts for this vehicle.

Thanks
Stephen
