We do have axles ready, retail is $415.00. Just finished Stage 1 build, should have them ready to sell by 1st of February. Got 3'' out of front and 2'' out of rear w/factory axles. Front is direct bolt on, rear will require drilling 2 10mm holes. Price not set yet but should be in line w/Commander at $249.00.
I have not adjusted the preloads on this machine. There are several inches available both ways for adjustment. I figure you could get at least another inch of lift just by adjusting the preloads up, maybe more
