Description
170-82-21X stub shaft for SPL170 — 3.858" spline dia, 38 splines, 9.193" engagement, 11.811" CL-to-end. Dana Spicer. Boot: 109-30-2-94M.
The 170-82-21X uses a 3.858" spline diameter with 38 splines -- a different spline profile from the standard 3.464"/34-spline SPL170 variants. This profile corresponds to the SPL170/SPL250 hybrid engagement used in some commercial applications where maximum torque transfer area is specified. The wider spline OD and higher tooth count increase the total tooth contact area significantly versus the 34-spline profile.
- Series: SPL170 (Dana Spicer)
- Spline diameter: 3.858" -- wider than standard SPL170
- Spline count: 38 -- higher than standard 34-tooth SPL170
- Spline engagement: 9.193"
- CL-to-end: 11.811"
- Boot cap: 109-30-2-94M (same as SPL250 boot)
The boot cap 109-30-2-94M is shared with the SPL250 family -- confirm this stub shaft variant matches your OEM application spec before ordering, as the 3.858"/38-spline profile does not interchange with standard 3.464"/34-spline SPL170 sleeves.
