L4's have always come with a big ring diff. Some early ones had a problem with the left hub breaking at the adjustment point, the IRS left hub is a direct replacement.
Another good upgrade is to replace the e clip front axles with some Lunsford titanium axles with nuts to hold on the wheels. From there the Lunsford 8/32 socket head screws to hold on the front arms are very nice and don't strip out like the kit philips screws
