Here's how to achieve the best ring & pinion contact pattern , every time, in just 3 simple steps!
Reading contact patterns can be daunting when looking at the average gear installation guide. They often come with pages of photos showing minute differences between contact patches needlessly turning people away from attempting the job themselves.

Learn from experienced drivetrain installers the quick and easy way to set a proper pattern every time with the only three images needed to tell where the gears are riding. Hear the difference between a bad/noisy pattern and a smooth/good pattern during the install process rather than on the road. Save time and money by following these steps.

This demonstration takes a 2014 Ford F150 from a 3.73 to a 4.56.
