8 3/4 rearend need help
i run an 8 3/4 rearend under a 80 backhalved malibu,it has a 406 with a glide in it.ive broke 2 ring gears in it ive put a 3rd set of 513s in it but now ive back braced the rear do you think this will make the gears last????
|
The only 8 3/4 out there is Mopar. You SURE it's an 8.75 ? They have a drop out punkin like the 9" Ford, and are usually pretty bullet proof.
|
im sure it has a 742 case with the big pinion,dumps out the front,like i said this is the second ring gear ive put in it but this time i put a rearend backbrace on it.do you think that will help the gear last?
|
The backbrace will help to some extent, but eventually you will need to move to the steel main caps and billet adjusters to get to a point of decent life from the gears. At the point it's better to just move on to something else.

if i can make through this season, im ganna build a dana 60,do you think they will last the rest of the season???

I have the same problem, was thinking of going to 35 spline spool and axels, checked with rear end shops, strange, moser and others they all said same thing, will break ring and pinions, this yr with new motor, and glide with brake, only left on 3500 chip on 2 step, next yr going to a dana 60 with 40 spline, want something that will live and then can bring chip on 2 step up more, will not put money in my mopar 8 3/4 will put in another s10 for wife
|
i hear ya i feel the same way,since last posting i put another 513 gear in my car i got 100 passes it broke friday nite....now i have another question.....im ganna build a dana 60 but i have 35 spline axles in my 8 3/4 can i use them if i buy a 35 spline spool for the dana??????
|
Mine is a 8 3/4, back brace it and go with billet caps this will stop your problem :!: The tubes are flexing too much i had the same problem :!: JMO Mark
