They are good! They have a lot of the odd fasteners that GM uses and for a great price too.

u should look into why they didn't come with washers, the flange might be engineered to flex minus the coverage of the bolt head....increasing the area with a washer might cause failure.
came across this on a coupling for a ballscrew on a high speed CNC machine I was repairing.

Please post their reply, I am curious as well and as ov said before the hardware kit is the only thing I don't care for with their shaft.

Will be interesting to hear what they say. Based on what I have looked at with mine, the contour of the flange will cause uneven pressure from the bolt & washer when being tightened down. Without the washer, the bolt will be on the flat surface.

I know it might sound stupid and it may not be relevant but after a very long briefing on rotational mass vs allowable flex it's better to be safe then sorry.

A washer helps distribute the load over a larger area to prevent warpage. There is no way that bolt could warp that thick flange so a washer isn't needed.

I'll be able to sleep better now!

So are you going to use them or not ?

is there any adjustment(s) for truing it up?
I'm thinking of tossing in a 1 piece when I do my axles but the forum is filled with unsatisfied customers getting bad vibration.
.. I haven't looked into it nor do I know anybody that experienced this so I just assumed that Joe's garage wasn't installing them properly???

no disrespect to any Joe's out there.... especially the ones that own garages named "Joe's Garage"

by any chance does the g in ur username stand for garage?

LoL no but people do call my private shop Joe's Garage.

why so quiet over here? everybody's ol'ladys take their internet privileges away after asking them for $15k to buy this engine?
