Applications
This 2.25-16 inner spindle nut fits wheel-end assemblies on:
- Drive axles specifying Meritor 1227U515 / R002417 inner nut (Meritor RT-series tandem drive axles using the 2.25 in spindle thread)
- Trailer and tractor axles specifying Spicer 12-408 inner nut
Confirm the existing inner-nut thread (2.25 in–16) and across-the-flats dimension (3.5 in) before ordering — heavy-duty axle spindles are also built for 2.625 in (1227-C-549, etc.) and other thread sizes that share the same general appearance.
