6 plate clutch pack and 40% ramp thrust plate mod is what you need

The diffs are 2-way as standard, its just that they only have 25% lock and very low pre-load.


Ive seen people try to weld LSDs though
You can do it but you have to take it all apart so same work as rebuilding it... Iv seen one with just the holes for the oil filled up with oil and thrust plates welded in the open position!!!
