06 ultra classic 124 S&S Bored 5 over. The ring gear keeps shredding teeth. Replaced the gear 3 times this year. Any advice.?
Are you using the 10/84 ring & pinion setup? High torque starter? 3.15 primary gearing or 3.37?
Which tuner?
get the 9/66 ring and pinion setup, won't break again,

I just want to add that along with a tune issue is the possibility of a weak compensator kick back. Especially if noted on hot starts. A properly set up 2014+ comp can make a huge difference.
Compression relief valves installed? if not does it have EZ start cams?

A weak battery also causes kickback.

:up: Often checking the simple stuff first can resolve an issue.
Assuming this is a 124 crate. I would also check if both compression releases are working. You can physically touch the top of them during actuation.
Does it still have the stock comp installed?
A 2006 Ultra would most likely have the OG 5 speed comp...

Ahhh, yes, only 06 dyna. It shouldn't be a problem then unless loose (but that would rear nits ugly head in other ways.
