here it explains it.

hey what i have in my revo is an 0s 18 tz and its crazy.
now what we do is drag race on aspalt and sometimes on dirt.
I also took out the drive shafts up front so its only rear wheel drive.

thanx for that input but not trying to be rude or ne thing but why would u take out the front drive shafts, isnt 4 wheel frive the whole point behind a MT? that kinda sounds stupid

u are right but mine is more for drag racing and it works better with the rear wheel but when i do want to go offroad and big jumps i just put the driveshafts back in.

dont you hook up better with 4wd and accelerate faster?

the proline roadrage tires hook up really well and u get awsome top speed

It depends what 18tz you are trying to installl. The link provided is the install for the tz-tx if your using the tz- p there are different mods needed because the cranks are different between the two motors. If your trying to install the P version let me know and I'll get you the info you need. If not follow the link's instructions and you'll be lovin the TZ soon enough.
