Description
The shaft features specific spline counts and length dimensions designated by the 1100M suffix. It is engineered to meet original equipment standards for torque capacity and operational durability within the specified S140 tandem axle environment.
Proper installation requires verifying the specific axle serial number found on the axle's identification tag. This component is intended for use in professional heavy-duty repair environments and should be sourced through authorized commercial parts channels.
Due to the nature of heavy-duty commercial axle components, precise fitment is dependent on the specific axle serial number and configuration rather than standard year/make/model parameters.
