To gain torque for take off power and towing.
To increase mileage
Gain top end speed
To regain normal torque and power after putting bigger wheels and tires on your vehicle.

Platinum Torque Ring and Pinion: This is an inexpensive ring and pinion of good quality that is appropriate as a replacement. It is also an acceptable option for re-ratio applications when lifting a truck and adding bigger wheels and tires. Perfect for off road applications and street use alike. These gears come in 8620 steel and are heat treated in a standard method. These will not be as quiet running as the Motive Gear ring and pinions, but they will get quieter as they are broken in. Not that they are real noisy mind you, just not super quiet like the Motive Gear line. More...

Note: Post production lightening weakens the gear and has a high failure rate.
The AX is also available with a micro polishing finish that decreases friction and further strengthens the gears.

Ring and Pinion Identification: When you want to know what kind of Ring and Pinion gears are in your vehicle you need to identify the differential type. The quickest way to do this is to read the information stamped on the outside of the housing. However, not all the information you need may be stamped on it or it may be so dirty and worn that you cannot find it to read it. If that be the case you need to count the number of bolts and observe the shape of the cover plate and use our chart to identify it that way.
