Axle Details

The Chrysler 8.75" axle was the primary axle assembly used in most non-compact (and some high performance) Dodge, Chrysler, and Plymouth cars through 1973. This axle features a drop-out style carrier with a 8-3/4" ring gear, 30 spline axle shaft, and was available in three different case styles with different pinion shaft diameters. This axle can easily be identified by its drop-out style 3rd member and the following markings: The '741' (41 case housing) will usually have a large 'X' cast on the left side, the '742' (42 case housing) usually has a large '2' cast on the left side of the carrier, and the '489' (89 case housing) will have a large '9' cast on the left side.
