Description

The Spartan Locker is a lunchbox-style differential locker engineered to provide robust, 100% lockup traction for demanding off-road conditions. Its innovative design eliminates the need for thrust washers, utilizing a streamlined spring and pin system for straightforward installation. Constructed from durable 9310 steel, this locker offers enhanced strength and reliability. This mechanical locker replaces the factory spider gears within a standard carrier case, delivering consistent and dependable traction. It is specifically designed to fit AMC Model 35 differentials that utilize 27 spline axles and have a 1.620-inch side gear bore.
