Any plans to make them for calibers?

Does this work with a 80mm bolt?
What would the size limit of the engines be with SR RKP 200mm?

Standard calibers wouldn’t be able to have duel setup

correct but e-calibers, tb 218s or any other flavor of truck with the same profile should work. but if thats what i wanted i guess i could pick up some of the other vendors gear drives.

but you still wouldnt be able to go do on the e-cals or the standard the tb218 you could. It isn’t about the profile it is about the length of the hanger

Guys, I have been using these exact drives and can answer any questions because marc is a busy man. Let me start off by saying these things are amazing! The torque and speed you get from a pair of 6355 is pretty impressive. I took my board with this drive to Thunder in the Mountains and it did great on both street and especially the dirt. Jake and @Lunasi also got to give it a quick try. The lubricant is just grease from home depot. I use the green lucas for heavy machinery (started with red but I like the green better :man_shrugging:t3:). I have several metr pro readings, can go up steep hills and have a max speed of 33 mph on the 17/42 setting. I still think i could get it to go faster plus there is one faster setting at 18/42! I am not being given anything by marc to test these but i offered to buy them after testing because I have fallen in love with gear drives! Having something so modular means I can always use it! Im very excited for people to try these out

He has them for caliber 2 trucks. My setup is dual 6355 on calibers

Grease is applied to the gear before final assembly.

I’ve developed a dual setup for standard Cal truck running pneumatic tires. :point_down: Also @Bobby is currently running the same setup. My Janux IC gear drive does not require e-Cal for a dual 6355s setup. Everything is designed around the standard axle length of regular Cal.
