What size is my diff ?


thos

Recommended Posts

Hi,

I've got an SEiW with a 3.92 final drive ratio and no LSD. I have now been offered a Viscous LSD from an XR4, but I've been told it might be a different size. I havent got my hands on the LSD yet, but something about it being 7" and my current diff being 9", or vice versa ?? Can anyone tell me what size my current diff is - or even how I can measure it ?

TIA,

Tom

It WON'T be a 9 incher, that's for sure.

It's *probably* a 7 incher, BUT, a 7 and a half incher should fit in, 'cos the 7 incher has a spacer to take up the slack as standard. BUT, if you have an early Sierra diff chassis, this may not be the case......

Measure the top mount of the diff for the answer.....
