Well my clutch shoes are wearing out so when i went to the LHS to get a manifold seal i picked up some clutch shoes he said he had regular and superduty ones both made by Traxxas. The superduty ones are made of a harder material and on the lable it says in parenthsis(SP?) says "For higher stall" and was curious to what this means? Would anyone mind to explain to me?
 
higher stall means that the clutch will not engage intell the mill hits a higher rpm.witch in turn when thay do engage.at a higher rpm your not getting lag to yous diffs.its instant power...
 
IMO yes its better..higher the stall and a higher rpm when it hooks up. with more punch off the line..
 
what about aluminum shoes? Wouldn't they be considered High stall?
 
Probably not. It has more to do with the spring used than the shoes. A heavier shoe will kick in earlier with the same spring as a lighter shoe.

If you want to make high stall shoes, all you have to do is shave a little off the back side of each shoe to make it lighter, then it will kick in at a higher RPM since there's less weight for centrifigul force to use.

If you have an engine that has a stronger low rpm powerband, you want the clutch to kick in sooner to harness the power better. And the opposite is true for an engine that produces more torque at a higher RPM.

MIP makes a shoe that has two holes on each shoe to help with this. The closer to the end you mount it, the heavier the shoe is. On my 18 maxx, I use the higher stall point, on my 21 maxx, I used the lower stall point. I didn't notice a huge difference with the 21, but I did notice a significant difference with the smaller engined maxx.
 
Well if you're in a high traction situation, having the clutch engage in a higher rpm can be very good, but if it's a low traction, you probably want the engagement rpm to be lower
