Because of the weight difference between LiPo's and NiCD's, the buggy started to do some weird things. Thats when the came out with the ballast weight to offset the lightness of the liPo batteries. Then they found that if you moved the battery a bit, the over all buggy was lighter and faster with the better handling caracteristics of the original B4. The New chassis was made and the B4.1 was born. Other than the chassis, they are the exact same.
That is not answering his question
tranny case is different, Out drives on the .1 are larger
shocks
slipper
rear hubs
slight changes in plastics (uprated towers, blocks, race pieces)
front axles
All Current B4's are B4.1's that are made and bought new
You can get a New B4 is someone has a left over from a while ago.,
If you are going to get into this. Might as well get a B4.1 or a B4 with all the parts to upgrade it to a .1 . It will just make things easier down the road
You could have googled it and found your answer in about 5 mins. But what fun is that.
