Detailed Product Overview

This InMotion wheel bearing and race set is specified for a broad range of rear outer, rear inner, front outer, front inner, and rear right positions, depending on vehicle configuration. It is a tapered bearing set that includes the cup and cone where noted in fitment, making it a direct service part for many full-size trucks, vans, and heavy-duty chassis platforms. The WTA38 is commonly used in applications such as Ford F-250 and F-350, Ram 3500, Chevrolet Silverado 2500 HD, and GMC Sierra 3500 HD.

Its universal-style bearing construction is intended for rotational support where friction control and durability matter. The WTA38 part number is also useful when searching for a replacement wheel bearing and race set for older and newer heavy-duty axle assemblies.

What It Helps Address
