Alrighty, since my 35s are fast wearing and the plans call for 38" hawgs, I think its time I waive bye bye to 4.10s and step to 4.88s. Now, I had always heard that genuine gears were crap, and yukon were the best of the aftermarket. Well, just to verify that, today I was doin searching, and it seems that people on other boards have been having alot of problems with yukon lately, mostly since they seem to have transferred alot of their manufacturing to china/india. Can someone recommend to me a good gear manufacturer, and a place to buy them? Also, I know I need thick gears for the 14ff since I have 4.10s now, is there such a thing as thick gears for the 10bolt, and if so, what is the carrier break on them? Finally, I think I can install the 14ff gears well enough, if not, friend of a friend lives about 5 minutes from me who has done all this before. Question though, on the 10bolt, will I need a case spreader to get the gearset out? I havent messed with the 10bolt so I dont know about it. Thanks guys.
