X4Pro Gearbox Upgrade

[madmax]

as alot of you know the rear gearbox on the X4Pro isnt up to scratch and has a big thing of destroying the pinion and crown gear's, what i have besigned with the help of my friend tony and his machening skills.

what we have done is fitted a bmax rear gearbox to the car, but we found a snag the bmax runs diferent bearings, so tony has made 3 collars that sit in the bearings with a little lip on them so they dont spit out.
another thing is that the gearbox top has the shock mountings moldings and i have removed them so i can use the X4 shock tower

one added twistjust to make shure the gearbox is bullet proof i have fitted the caster metal gears. i will be running it this weekend at southport to see how it goes

will put some pics up soon and a report of how it works
