Spline length note: 10.335" spline engagement is among the longest in the SPL170 family, providing maximum torque transfer area. This extended engagement is required for high-peak-torque applications such as heavy-duty extraction vehicles.

The 170-82-71XS is a Dana Spicer SPL170-series yoke shaft engineered for the most demanding heavy-truck and off-highway applications. SPL170 carries a higher torque rating than SPL140 or SPL100 and uses a 3.464" spline diameter with 34 splines. The 10.335" spline engagement on the -71XS variant provides the largest load-transfer area in the SPL170 yoke shaft family. Boot cap: 100-30-2-156M. See also 170-82-71X (non-S suffix, same dimensions). This stub shaft is equivalent to the standard 170-82-71X -- the S suffix indicates a stocked variant; verify spec sheets for any dimensional differences in your application.
