You are watching: Posi rear end for chevy caprice
Can anyone phone call me what this axle is and also why it has actually NO axle code stamped ~ above the tube!? to trust me i have actually removed it cleaned it n over there is no password what therefore ever? i am 99% sure its not a 8.2! every it has is the tiny plate ~ above the left of the rear cover along with "use minimal slip oil only" on the ideal of that (see pictures) please help me decode this? I come from a 1978 caprice sedan i know its a 2.41 posi however where to be it made and what devision? have the right to i acquire parts and also what will certainly be the lowest ratio it will carry? I"m guessing 273"s?Code ~ above the tag reads (2NR-B 2.41 062 2)Other info on the facility housingB288 Guessing date code1231502 & GM52
I view Spider gears in there and thought the was the indicator that an open up Rear and Not a Posi. Therefore is his pic in reality of a posi differential? Can"t sell much assist in what else he to be asking and it looks favor an old post. Simply curious if that actually has a Posi diff pictured there or not.
It"s 100% a posi in there, you can see the S sping and also the bowl packs. It to be an choice on caprice/impala. If friend ordered one with G80 or G92 choice you got posi (old kind posi trac like my one) or a 3.08 ring n pinion favor the behind i simply picked as much as rebuild. Many came through a weak 7.5" open! The 2.41 behind lights both wheel if i stomp that so the posi is great but the 2.41 ratio sucks! The newer 10 bolt i,m structure will have actually late kind Eaton posi and also 3.08s, v a TH350 the will acquire it moving of the mark better i hope 2.41 is much FAR to higher gear!
There room a couple of Cadillac Forum 77-81 men that would like that posi.Double inspect your axles ~ above the 87 once you order your Eaton, it will likely be 28 spline, no the later on 30 spline.
Thanks for that, I have souced this (picture below) 8.5" C clip 10 bolt native a 1987 caprice, as it had actually a performance
ratio it obtained the 8.5 no the crappy 7.5. I"m strangly enough in the center of fitting a brand-new Eaton posi and new 3.08 ring one pinion, at the time of this post popping ago up? Weird! factor is i,m not sure if the parts will to the right the irregular type rear so just picked increase a newer one to rebuild. I"ll keep that 2.41 posi though, sounds a little rare!
Yes i would store that behind end, in reality if i ever found one more one, id simply buy the to have it, i wish i can have taken the one i checked out in that pic. I myself just got a rear end out the a 96 impala ss that im in the procedure of placing in mine 79 caprice that has actually the crappy 7.5 with an open up 2.41. I have the right to burn that one tires off lol yet i cant wait to gain the 8.5 3.08 posi in and see how it responds on the street!

There room a few Cadillac Forum 77-81 guys that would like that posi.Double examine your axles ~ above the 87 once you order your Eaton, the will most likely be 28 spline, not the later 30 spline.
Yeah, it"s a 28 spline but it"ll carry out for mine application. Shame it wasn"t a 30 spline though, could sawp the shafts out yet my people are an excellent so probably leave lock alone.
Yes i would store that rear end, in fact if i ever found another one, id just buy the to have it, i wish i could have taken the one i seen in that pic. I myself just obtained a rear finish out of a 96 impala ss that im in the process of placing in my 79 caprice that has the crappy 7.5 with an open 2.41. I can burn the one tires off lol yet i cant wait to obtain the 8.5 3.08 posi in and see how it responds ~ above the street!
The SS rear will certainly be nice v the bowl brakes aswell! i kinda wish i went that route now yet they room 5" PDC and also i have actually just bought new 17" wheel so i"m stuck to 4.75" PCD! my caprice is only a mild yet high talk 355ci (350hp 400 lbf) no plans to walk wilder so ns think stock rear with brand-new parts will certainly be good! i hope...

It"s 100% a posi in there, you have the right to see the S sping and the key packs. It was an option on caprice/impala. If friend ordered one through G80 or G92 choice you acquired posi (old type posi trac choose my one) or a 3.08 ring n pinion like the behind i just picked approximately rebuild. Most came through a weak 7.5" open! The 2.41 behind lights both wheel if ns stomp that so the posi is good but the 2.41 ratio sucks! The more recent 10 bolt i,m building will have actually late type Eaton posi and also 3.08s, with a TH350 the will acquire it moving of the mark better i hope 2.41 is far FAR to taller gear!
Yeah, i really wasn"t sure on the rear. Good to have a posi, but that gearing is no gonna put a laugh on your face.
