LSD diff conversion

[jakescicluna]

G'day, just wondering if anyone in here has done an LSD conversion from an open diff, wondering how much it costed and what you needed in terms of tools. Thanks!

I have an 2013 VE s2 SV6 fitted with an open diff if that helps.

Cheapest way is to buy a complete rebuilt LSD diff. It cost me around $3,200 for mine, plus another $400 to fit it. Pretty difficult job to build the diff yourself. You wouldn't really attempt it unless you have built a few doffs before. A ZF is a more complicated build than an M80 is. You really need a spare housing with the back cover milled off to set them up. If you don't get the set up right it won't last long. Very few places do them due to the difficult nature of building a ZF.

I am more talking about buying a second hand LSD and just straight swapping it for my open diff, or would that not work?

That should work.

easy swap bolt in and speedo corrects it self in the VE, cost really is the cost of a good 2nd hand diff. Lots of V8 guys swap to lower ratios so shouldnt be hard to get a good one..

I see this is 12 months old but yeah just buy a second hand one easy fit
I picked a 3.7 lsd $1500 from commodore dismantler on the Goldcoast he sent it in to diff specialist checked it over put new bearings and seals in it
This was 2 years ago and 3.7 lsd very hard to find
A mate of mine got a 3.36 lsd $600 put on hoist 2 hours had old one out and new one in he had 2.7 open added 1000rpm on hwy at 100kph
