Okay guys I need some advice. I just picked up a TNX pro truck w/os .18. I haven't gotten it in yet but need to know if I can convert it over to a 5.2 version so I can drop a BB in it. I can't seem to find a good place for advice on this. I heard the 5.2 is lighter also. What is different between the 2 to make it lighter besides 8 shocks versus 4? Basically looking for any tips.
