dump the quad track ...pick up a Dana 300 ..... get the spring perches swapped so they are on top the axels ...gain ya about 4inch ... you should allready have d-44 diffs ...if not find an old International scout and get the diffs ...be sure to correct steering geometry ...goin Spring over ...you can fit 33 Boggers or TSLs or alike ..... I actually like Biased ply boggers for rock with bead locks .... the lugs act like fingers grasping the rocks when aired right down ...pretty good if ya wanna get muddy to
friend of mine put in brake line locks .... a mod you might wanna look at doing ...
For under 4k USD you can do all that i mentioned as long as you are willing to do some work .... swapping the spring perches ... get a pro to do that
