... Launching a 4x4 cos with big power will mean spending 10k+ at least on the tranny...... or it's wreck and repair on the cheaper stuff, simple as. Good as the Mullet boxes are, the mainshaft will always be a problem as you have to work your upgrades into the original dimensions.
I have a thick wall front with an atb dont think i can go back to open as the casings have to be machined. I have the mullet box but it only has the gear kit not the shafts (which is why i came home on a bar) But i keep snapping drive shafts i think the diff is one of the big reasons due to the fact the atb locks so when one wheel finds grip it rips the other apart.
