I haven't talked to the guy from zukination as of yet... I doubt he's finished his R&D as I think he's been quite busy...
There are really a number of problems of which why our vitrackers are not as easily moddable as their older kin
I think the body design was developed cab-forward style to maximize leg room and space... problem is it doesn't leave much fender to cut (if any) and reduces the ability to put larger diameter tires
Solution? Body lift
Then you run into another problem... brake lines etc.. of which will need to be extended if you are to install a combo lift of over 4"
I think the Frame is too wide as well.... This comes into play when installing a suspension lift as the front stock a-arm will pull in (in my case over an inch)
Solution? Only Calmini I know of has a set of a-arms of which they will not separate
Then the next part... the front diff... ugh
CV joints start getting quite aggressive after 2" of lift
Solution? Diff drop bracket, but I have not heard of any success as of yet
Talking to Jeff & the guy from Boondox, there is a potential of the diff drop bracket causing issues with the carrier/3rd member due to the driveshaft angle
So you might give one issue up for another (I'd rather deal with a much cheaper rebuilt CV)
It'd be great if there was a perfect kit
but even Jeff's kit was quite cumbersome... meaning that new rear shock perches and links would have to be replaced and even re-welded (using curry joints)
Thinking about it...
With the coil spacer lift I have in right now... I think I'll be happy with the RRO 2" BL, and a set of front wheel spacers running 32" pizza cutters (235/85/16)
build up some cosmetics and functional things like tow points and winch mount bumpers
and if required Gears/locker
anything more hardcore... I hate to say it, but I'd probably buy something domestic and cheap to use only on the trail
Always wanted a Ramcharger
