West Coast DifferentialsWe Make the Difference.

At West Coast Differentials we are committed to making

your experience with us totally enjoyable. We think top-notch

customer service is the most important thing we do.

By asking ourselves what makes us different than other companies,

our answer is that we deliver the level of customer service

that other companies only promise. At West Coast Differentials,

We Make the Difference is much more than a slogan.

Our goal is to distribute the highest quality differential parts available

at a competitive price. We expect to make sure our customers

get the right parts the first time. We organize everything we do

around these concepts. When problems do occur, we distinguish

ourselves by how we react to these situations, and in the process,

gain some of our most loyal wholesale and retail customers.
