We are working hard to get you what the customers have requested; with more technical pdf's and printouts in works.
Here is an updated gear and tooth count PDF to use for referencing ratios. With older models pre-1980 still in use, some planet carriers have 3, 4, or 6 planet gears, if you need more help give us a call!

The Performance Bearing 360/2bbl sprint car was at its first race a week ago. A dual race event in Mountain Home Idaho was the site. Trying to teach an old straight line dog the new trick of turning left was quite a chore. In addition, learning tire stagger, shock rates, torsion bar weights and block heights, it was a full on mental over load. It was a great time, racing with my son Ryan and the other great racers at the event made it very enjoyable. I think driving into a turn at 90+ mph, turning with the throttle and turning right to go left will become easier over time….. as for now, there is and always will be a great amount of respect for those drivers who make it look easy.

Thank you all that commented and messaged us earlier this week!
One of the topics mentioned was gear ratios and which one to choose. Here are a few documents we use to assist our customers, as we are developing more pdf documents and videos as well for use.
Let us know if you have more questions!
