Does a 960 IRS Differential fit in my 90 760?

[mo5005]

Instead of replacing the entire rear end, I was wondering if I could just swap out the center differential off a 92-94 960 into my 90 Volvo 760.

yes sedan fits in sedan.

 

[blkaplan]

if they both have IRS then yes

I don't see any performance gain though. Aren't they all 3.73 LSD on the IRS cars?

Well seeing as he has a 760 some of those came with an open diff. some came with lockers. but all early 960 sedans and /940se sedans came with lockers

Jonathan...never say always. Volvo did Volvo things.

 

[okoye]

you mean the 420?

 

[Lord_Athlon]

Yeah. Nothing they did made sense. It was sort of "whatevers on the shelf"

6 cylinder mk1 and 4 cylinder mk1 irs have different ratio's. also the drive shaft flanges are different.

Yes, I put a 3.31 lsd pumpkin out of a 960 into my 89 780......,then pulled it and dropped it in my 91 coupe.
In Canada, all 960s got the "winter package" lsd diffs. 3.31lsd was a good all around match with my m90.
Yes......just unbolted drive flange from diff and installed the one that matched the driveshaft.
