Felony No shims on the felony diffs? Hmmm...

[Harriot10]

Exactly... ☝.... I wouldn't focus to much on the internal shims unless that is something you want to do.. I'd be more concerned about the ring and pinion backlash... 13x16...

I originally went 10k f 500k center 50k rear.. amazing difference both in drifting and straight line pull.. the 500k allows that 7% over driven front to pull the rig which makes drifting and straight stability so much better..

I now have 30k in the front.. ?.. the 10k diffs out a little to much, cooking off the "power side"...

Is this what I need??‍

Size is correct.. I would go with a .1 or a .2 thickness.. those are .15.. they might work for ya and are not bad to have around.. my particular situation I ended up using .2 of shim in each diff...

Ordered about $50 worth of shims today. Diff fluid is scarce like shock oil!?? All I have on hand is 100k, 50k, and 30k. I guess that’s better than nothing!?‍ All my 6s diffs are getting some love next weekend!
