might as well keep it BG it aint worth squawt otherwise no matter what all mods it has.
From my experience which is alot with the slash as it is the most used and abused truck ive ever owned.
ditch the flm tranny mine gave me more trouble than anything else on the truck..... use the stock tranny with the rpm bumper mount makes it bullet proof in the rear
Build the stock shocks with at least aluminum caps and 60 or 70 wt oil all around (handles great like this) i use 1/8th buggy fronts in the rear
get the ST racing captured hingepins (best mod yet, next to the rpm front chassis brace/skid thing)
use the rpm chassis braces, fixes steering rack issues and much stronger design.
the trick to keeping the retaining rings on the cvds is to CA glue them

yep once they are in place put a drop of ca glue of the table and take a tiny flat screw driver and get a little on it and just put a couple tiny little dabs on the retaining ring and walla they only come off when you get some acetone and want them too.
Get the Rpm shock towers or aluminum towers because the stock ones provide too much flexx and will lead to bent shafts and a poor handling truck.
there is no true fix for the diff unless you buy the flm, so just put some oil in it and let it go for 2-3 months and then fill it back up....
if prepared right it really is a tough truck.... mine has been running on 3s and 9L since it was released and its held up to alot of crap and alot of other people driving it also.....
