Overall width is alittle over 2" wider per side. Keep in mind I also converted over to LTZ-400 spindles & hubs as well. As far as bump steer goes, there is very little.

The progressive springs on the LTR shocks seem to be what my zilla really needs.

Mitch, if you want, I can take as many pictures for you as needed so that you could duplicate these arms. What I should do if I get the time is make a jig to reproduce these. The only thing is that these are not a bolt on item. There was some frame modifications that needed to be done for the pick up points. BUT...  the ride is well worth it in the end.
