Ring and Pinion Break in Procedures and Oil Specs - Revolution Gear

Ring and Pinion Break in Procedures and Oil Specs - Revolution Gear

When installing a new ring and pinion it is recommended to properly break in the new components. The proper break in procedure will extend the life of the components and
help with the prevention of premature failure usually caused by extreme heat. Although your new ring and pinion is “Lapped” from the factory for smooth quiet operation, they will still need to be broken in once they have been installed.

Common Differential Carrier Breaks

Common Differential Carrier Breaks

What is a Carrier Break?

A carrier break is where the divisional split between higher and lower gear ratios occurs. (One differential is used for higher ratios and one for lower). Carrrier breaks are common in these makes: GMC, AMC, Chrysler, Dana Spicer, Toyota.

It is important to know what current gear ratio you have and if a carrier break exists so that the correct differential is used. Aftermarket gears can be found in thick cut style, which are manufactured to overcome the carrier break and take away the need to switch carriers.

Guide for Differential Lockers

Guide for Differential Lockers

What is a Differential? 

The differential is a device that splits the engine torque two ways, allowing each output to spin at a different speed. The differential is found on all modern cars and trucks, and also in many all-wheel-drive (full-time four-wheel-drive) vehicles. These all-wheel-drive vehicles need a differential between each set of drive wheels, and they need one between the front and the back wheels as well, because the front wheels travel a different distance through a turn than the rear wheels. 

Part-time four-wheel-drive systems don't have a differential between the front and rear wheels; instead, they are locked together so that the front and rear wheels have to turn at the
same average speed. This is why these vehicles are hard to turn on concrete when the four-wheel-drive system is engaged.
