Gear Ratio Change

We can fine-tune your car

What is a gear ratio?  In relation to an automobile, it is the ability of a smaller gear (input gear or pinion gear) to turn a larger gear (output gear or ring gear) in order to achieve a certain goal:
High Speed or High Torque.

Larger tires require a HIGHER number ratio (.456 .488 .513) to turn them properly. Smaller tires or high speed applications require a LOWER number ratio (.241 .256 .273) to achieve a higher overall speed.

We work on all makes and models.  We carry a large inventory of new and used gears. When you need a gear ratio change and your differential done right, call
