West Coast Differentials We 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. Index

BK - Basic Kit: The Basic Bearing Kit is assembled for the fully stocked shop and includes only the basics for differential repair: pinion and carrier bearings, pinion seal, o-ring (where applicable), pinion nut, and crush sleeve. Our Basic Kit part numbers begin with the prefix BK.

IK - Installation Kit: Our most complete kit, the Master Installation Kit comes complete with everything you’ll need to rebuild the center section of your differential. These kits include the following, as needed per application: pinion and carrier bearings, pinion seal, pinion shims, pinion nut, crush sleeve or depth shims, ring gear bolts (most applications), o-ring, gear marking compound & brush, Loctite, cover gasket or silicone, carrier or super shims, slingers & baffle, and installation instructions. Our Master Kit part numbers begin with the prefix IK. MK - Mini Kit: The Mini Kit is ideal for low mileage gear ratio changes and includes everything but the bearings, as needed by application: pinion seal, pinion shims, crush sleeve or depth shims, ring gear bolts, o-ring, gear marking compound & brush, Loctite, carrier or super shims, and installation instructions. Our Mini Kit part numbers begin with the prefix MK. PK - Pinion Kit: The Pinion Kit is ideal for low mileage gear ratio changes or for budget repairs when only pinion bearings are needed. The kits include pinion bearings, pinion seal, pinion shims, crush sleeve or depth shims & o-ring (where applicable). All of our Pinion Kit part numbers start with the prefix PK. IPK - Internal Parts Kit: The Spider Gear Kit or “IPK” replaces the internal differential components and includes side gears, pinion gears, side and pinion gear thrust washers, cross pin shaft, and cross pin bolt.

Transfer Case Kit: The Transfer Case Kit is a complete bearing and seal rebuild kit and includes bearings, gaskets, seals, shift fork inserts and small parts (where applicable). West Coast Differentials Products

Ring and Pinions: Our most popular ring and pinions carry the Sierra Gear label. These are reasonably priced and the highest quality aftermarket gear sets available. We have a complete inventory of OEM ring and pinion sets for Chrysler, Dana, Ford and GM axles. We also stock US Gear and Richmond Gear ring and pinion sets.

Installation Kits: We package our own kits using only the very highest quality components, most of which are OEM. We have the most comprehensive line of the most complete kits in the industry.

Differentials: West Coast Differentials stocks open differentials, limited slip or positraction differentials, and automatic and selectable locking differentials as well as spools. These are available from OEM manufacturers, Auburn Gear, ARB, Eaton, and others.

Axles: We carry stock replacement axles and performance aftermarket axles. In stock replacement axles we have OEM and American made shafts, as well as high quality aftermarket shafts in the Sierra Gear line. Performance axles include chromoly and standard alloy shafts with stock or upgraded splines, as well as cut to fit shafts for custom housings.

Third Members: West Coast Differentials can assemble third members for Chrysler 8.75”, Ford 8” and 9”, and various GM and Toyota axles. We will build them with any ratio, differential, housing and yoke available. Most will be assembled and shipped not later than the day after you order!

This catalog includes listings for our most common parts and the most common differential applications. We also stock (but do not list in this catalog) individual bearings, seals, shims, internal parts, tools, used parts and parts for less common differentials. If you don’t see it, ask!
