Question:
I AM LOOKING FOR A PART NUMBER FOR THE AXLE SPINDLE NUT AND WASHER THAT HAS AN I.D. OF 3/4. WOULD FIT THE AXLE THAT USES THE DX22XR HUB. WE RUN INTO THIS SMALL SPINDLE EVERY ONCE IN A WHILE AND I CANNOT SEEM TO LOCATE THE NUT AND WASHER ON YOUR WEBSITE. THANKS! NATE

Hey Nate,
We do not have a 3/4" spindle nut or washer, the smallest option is the 7/8" spindle nut # 165931and a 1" washer # SW1000. I cannot find anything smaller.
Are you sure the threads on you're spindle are 3/4"? If they nut is actually 7/8", the above spindle nut and washer will be correct. The washer does not fit perfectly to the spindle, it is just there to give the nut more surface area to contact the bearing. Most 2k and 2.5k axles don't even use a washer to be honest.

Yes Sir, the outer bearing is a LM11949 with an I.D. of 3/4" and the nut is the same size.
