The OEM light and medium duty planetary carriers are fit with a rotating outer thrust washer assembly. Due to their propensity to rotate, the washers quickly erode when exposed to high thrust loads, such as those encountered in high performance street and strip applications. To increase the service life and performance of the component, the OEM heavy duty carrier is fit with a revised thrust washer assembly. Two integral locating tabs "ground' the outer washers to the carrier housing during thrust loading, prohibiting rotation, which vastly reduces washer wear. This output carrier is an excellent choice for all high load and off road vehicles which spend extended periods of time operating in reduction. Plenty of stock as of 11/2022.
