Ok first of off im getting ready to re-build the rear in my 71 c-10 with posi and gears, my axles are junk around the bearing race so I'm planning on replacing them and putting a griddle type rear end cover on for the strength. Now reading some of the older posts about c-clip eliminators it seems that the consensus is unless your running big inch cubes and slicks, and the rules say you need em, that there not really needed, if I go with a quality axle? Now according to the Moser site there aftermarket axles are larger so would i need a different axle bearing? Any of you all used Superior axles? iv got there stock replacement ones in my blazer but was wondering if any one had used there evolution series ones, i ask because their cheaper, I don't mind shelling out for the Moser's but if i could save some coin im all for it. O yea up front is just going to be a built 350 should be around 400ish hp but down the road I'v got a 454 to build for it. Thanks for the replies.
