great truggy. love mine, its box stock. not one single upgrade. very durable too and comes with some great bearing. i bought a bearing kit from a broken down X2 off ebay for back up and havent needed any so im using them on my HB D8T which i run now. still have the X2 CRT though. easy to setup also. i ran 7k front 10k center and 3k rear and 40wt in the shocks all the way around. works at every track i have been too. the only problem really is they use half offset wheels and most people run zero offset now. but to be completely honest with you the HB D8T blows the jammin away in almost every way, and its cheaper. i would take a look at the D8T before you buy. but the jammin is great too.
are you buying the pro kit or RTR? if RTR it will need the kits shock towers.
my rating on the kit from scale 1-10 is a 7.5-8.5 just depending on the track. and HB is a 11
