Description

The Yukon Grizzly Locker is a robust differential upgrade for AMC Model 35 axles, specifically designed for vehicles with 27 spline axles and a gear ratio of 3.56 and up. Its patented internal design is engineered to minimize common locker failures, while the use of 8620 internals ensures enhanced strength and durability for demanding off-road conditions. This locker is proudly assembled in the USA, reflecting a commitment to quality manufacturing. Technical notes indicate that this unit is double drilled to accommodate both 3/8" and 7/16" ring gear bolts. It requires carrier bearing and race part numbers LM102949 & LM102911 for proper installation. The product is listed with a gear ratio of 3.54, aligning with its compatibility for ratios 3.56 and higher.
