Overview

The Ratech 302K is a differential installation kit designed for Mopar 8.75 inch axles with a 489 casting. This complete kit includes essential components such as bearings, crush sleeve, gaskets, hardware, seals, shims, and marking compound.

Ratech emphasizes the superior quality of its shims, manufactured in-house using hardened American-made shim stock. Unlike softer sheet metal gauges, Ratech's shims come in precise .002 inch increments, offering a broader thickness range and preventing splitting during performance applications. This ensures accurate gear set specifications and eliminates gaps in the shim pack for precise installation.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
