What posi unit for 10 bolt

my wife has givin me the ok to spend a few dollars on my truck and I was wanting to get a posi unit. Ive read on severak different brands but wating your opinion. my truck is well under 300hp so thats not a factor. Mainly want posi for traction purposes cause the rearend is pretty light and we get snow often. Looking to spend a little less than 1000 bucks for a nce dependable daily driver posi unit. oh by the way my truck is a 86 chevy C-10 with 10 bolt rearend.

300hp and a 10bolt in a truck isn't to bad it should live fairly well. If you are ever going to do any horse power mods in the future though you should consider a 12bolt now, if not just install a factory style posi, good enough for daily driving. The one prob with the factory style type is most have clutchs but employ a govenor style engagement which means a bit of wheel speed first to engage, usually with a bit of clunk. Ya they do kind of suck now that I think of it. Anyway if you do want a posi try to get a clutch type only no goveror springs in case.

Probably just a factory unit is good then. Have you ever installed a posi carrier assy, if not sure it may be a lot easier to by a complete good used diff and just swap the complete diff. That way you can choose a diff ratio if you want too, just a thought.

Did you check the installation link that I left in your other thread? Better check it out before you get started. When you order the Eaton be sure that you get the bearings and shims that you will need to install it. A new set of ring gear bolts is also a good idea.

Price is very reasonable, I'd jump on the deal and run it till it blows for that price. Give it a lube change and examination for any obvious defects while the cover is off.

Likely is is going to be the weaker Gov-Loc differential, but if you treat it normal it will last for a while.

What if I wanna peel out every now and then. Will it hold up to that. I guess if it goes bad I just put my old back in right?

Whatever it was it isn't there anymore. Do you want something that's going to last or are you just looking for the best price?

Called a local rearend rebuilder here in town and asked about getting a posi in my truck. he quoted me roughly 700 bucks for a new posi unit installed and mentioned that does not include rebuilding the entire rearend. Should I get the rearend rebuilt or whtever that means and does 700 bucks sounds reasonable for just posi unit installed

I would assume new bearings, seals and shims. I would clarify if this includes new outer axle bearings and seals Best let him tell you what he means. The $700 sounds very reasonable. I paid $750 several years ago that included the works. New posi units for the 10 bolt can still be found but are getting more difficult.
