Description

Quality replacement rear axle shaft assembly for the left (driver) side. Heat-treated and precision-machined 1541 Manganese steel construction to handle maximum drivetrain torque in commercial truck and heavy-duty applications. It is a semi-floating axle shaft with 30 inboard splines, a length of 33.11 inches (840.994 mm), and a 6 x 5 inch wheel bolt pattern. Designed for vehicles with a GM 8.625 differential and is non-ABS. This part restores correct axle shaft geometry and drivetrain reliability. Marked as obsolete/discontinued by Dana Aftermarket.
