New GT billet aluminum gear carrier housing is designed to handle higher torque engines such as diesels. Housing is drilled for oil delivery directly to the mainshaft bearing and has an inner shield to keep the oil focused on 4th gear and the bearing. Mainshaft bearing is better supported by a 4 bolt hardened steel retaining plate. Original housings only retain part of the bearing. Housing is tapped for ease of use with oil cooling systems. It is also pre drilled for the 4th gear oiling plate. Machined from billet T-6 aluminum for light weight, strength and durability the GT gear carrier retails for just $1095.00.
