Sierra LSD fitting to a Mac1 ZR
CosKev3 - 11/10/14 at 04:29 PM

When I dropped my car off the axle stands the rear end would not compress down lower than the wishbones being level,I didn't realise the Sierra LSD was wider than the non LSD
So the ZR rear end is designed for a non LSD, and I have fitted a LSD so the driveshafts were bottoming out and stopping the suspension compressing.
Quick call to Mac1 and they told me about the LSD being 10mm wider each side, so they supplied me there 12mm spacer they have made up for this problem.

Just thought this might help someone out in the future if they upgrade etc to a LSD set up

There are 2 sizes of Sierra diff
7" and 7 ½"
There are LSD versions of both
I think you fitted a 7 ½" LSD in place of a 7"

No it's deffo a 7 inch lsd from a xr4x4, I would have had to alter the chassis to fit a 7 1/2 inch diff in or chopped up the mounting point on diff, neither of which have been done.
