Differential Services
Fluid Service
Your differential requires periodic oil changes just like your engine. It is commonly neglected among drivers but a crucial service. We recommend changing your gear oil every 30-60K Miles. Sooner if you tow regularly.
Rebuild & Replacement
A differential rebuild is an in depth process requiring specialty tools, precise measurements and a lot of patience. If you suspect you have an issue get to Differentials Plus for a complete evaluation. We offer minor and major rebuilds along with full replacement options.
Re-Gear
Re-Gears are most common in off-road vehicles and in the racing world. Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds & better fuel economy.

What is a Differential?
A car’s differential is a key component that transfers torque from the driveshaft to the drive wheels. Unlike the transmission, it’s part of the axle assembly and manages wheel speed during turns.
The differential allows wheels to rotate at different speeds, essential for smooth cornering. For example, during a turn, the outer wheel travels farther than the inner wheel. All-wheel-drive vehicles usually have two differentials—front and rear.
