if you want to get technical, you CAN put the 2 speed in it and jump. As long as you aren't on the throttle when you land you should theoretically be ok because the clutch bell can spin freely. I had my 2 speed in and did some serious jumping and only stripped the spurs once and that was because of the motor mounts coming lose.

I'm not saying it won't work and that it will break every 5 minutes. I'm just saying, expect to break parts if you offroad the 2 speed. I did it expecting to break something and just got lucky.

you are correct about the savage tranny. All of the gearing is internal and on the outside of the transmission is the spur gear which has a slipper setup.

I'm definitely looking to get him out there and bashing around. The more the merrier! I don't think we have had all our trucks out at once yet. We found out last time that me and my buddy who has an 18ss have the same frequency in our trucks which sucked because I wanted to run his 18ss against my OS.
