Alright guys I'm the one making the internal reduction and I'm here to answer any questions you have. I was not aware scooterchris had left the forum until yesterday when I spoke to him and we agreed I needed to get on here and sort of take over where he left off. In regards to this post the problem with Colby's machine turned out to be electrical, the valvebody oil pressure switch connection got wet which threw the machine into some sort of limp mode and didn't allow the clutches to grab. I saw his original post on Facebook and immediately questioned what actually went down because I had a feeling he was kind of jumping to conclusions. He said the machine was pulling fine then just quit all of a sudden like it was in neutral. As soon as I heard that I knew it was not a normal clutch slippage problem. The clutches aren't gonna go from holding fine to nothing just like that without there being some sort of electical failure. Anybody that's experienced what the slipping clutches feel like knows they don't just go from holding fine to 100% slippage. We've got about 10 other machines running now with the reduction and no issues. The reduction is intended for a certain tire height range which ideally needs to be no larger than a 30/31" tire because at that point you're going beyond the 25% reduction amount on the height compared to stock and you start losing the more positive clutch engagement. That being said we originally tested the first machine which was Colby's on 32" Silverback tires (aired up to a true 32) which are super aggressive mud tires and it handled them very well in deep mud and better than I expected. I'll also note while I'm here that we've got an updated version of the reduction now that doesn't have the louder whine that the original version had. The new version is no louder than stock and I have a short vid I'll post on the original IGR post but we are gonna be getting more vids very soon. I knew the whine was disliked and tried several different things to come up with the best fix, it's just taken a while. The main thing goal from the beginning was to see if it was possible to even do a reduction at all then to see how it would perform, I knew I could get the whine out of it, just a matter of time and trying different things. Thanks for your time guys and like I said I'm here to answer any questions ya'll may have.
