I just picked up a used tranny from a guy and forgot to ask him what the best spur and pinion are to run on it...so im going to ask everyone out here....If it makes a diff im running a goat 3s and a 21.5 motor
Any help would be great

Thanks

I have run the standard 87 tooth spur gear, and the 86 tooth Robinson spur as well. The plastic ones are quieter...I like that. As for pinion gear, I like 18 tooth.

spur and pinion is a personal call i dont know how you drive

I've been experimenting and have found so far (first crawler, stock 87t spur) that the 25t pinion i have is a bit to quick and the 14t I have just doesn't quite enough kick that I would like to hop in certain situations. I think I will be going with 2 more pinions somewhere in the middle, maybe a tooth or 2 difference and I think I should find something that will make me happy.

By the way, did you buy the tranny from Sam?

Thanks for the info guys....the truck is going to be 70% trail and 30% rock.....nothing to hard core just out for some fun

cagedcbr...no i did not get it from Sam...LOL...i picked it up from a guy at school

if youre going to be using it mostly for trail bashing you can get away with more wheelspeed 87/20-25 should be cool
