I have a quick quetion to ask. Whats the diffrent between a 40/40 prop valve,an the 30/30 prop valve? thanks

 

it's a ballance meter and should be to balance the front breaks from the right tire to the left tire. so say it 80-20...so you would have a prop valve of 40/40 on the front...i'm not a 100% sure so do your research but i'm pretty sure i can atleast get the ball rolling on this one. good luck

oh also i believe the 40/40 prop valve would be larger in inside diameter...but still do some research on it
