If you are using pinion to gain traction, you are simply robbing horsepower and this gives you the feeling you are getting traction and less wheel spin. You have to figure out with your set up how to use the max horsepower and hook it up. As far as bearings and grease, and setting the front end, call me. It is to bad we are all so spread out, I really need to do a set-up school and go through the whole process.
