Overview

The Powertrax Lock-Right Locker is a mechanical locker designed for GM 7.5-inch, 10-bolt differentials with 26-spline axles. It replaces the spider gears without altering ring and pinion settings, offering the straight-line performance of a spool while automatically unlocking for smooth differentiation in turns. This locker reduces noise, tire wear, and drivetrain damage associated with other locker types, and can typically be installed by a home mechanic in a few hours. Note that a carrier is not included with this locker.

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.
