Question:
Hi, Im looking for confirmation that the spindle TRU37FR will properly mate with the hub AKIHUB-865-7-2-EZ-K . Additionally, is there any way that I can get a .STEP file or detailed drawing for these parts? Thanks!

Hey Ashton,
They #42 spindle # TRU37FR and the idler hub # AKIHUB-865-7-2-EZ-K are going to work well together. The idler hub is designed specifically for that #42 spindle. Unfortunately we do not have any .STEP files for these parts, just the photos we have on the site.
What kind of trailer are you looking to do the work on?

I should be able to get most of my work done with the dimensions. Can you find the shaft diameters on # TRU37FR? I saw another expert gave the lengths. Thanks!
