ok guys i have found a new source for steel e maxx idlers. they are made of hardened steel and work very nicely. i just put one in my trans and it is as quiet as when i had the plastic idler in it. the bearings fit in perfect and the tooth profile is just like the original ones.
granted i have only made a few runs with them but since they are made from hardened steel, i cant forsee any wear problems.
Tom, the guy who makes them wanted some guinepigs for them and he has responded to all of my questions quickly and proffesionally. he shipped them out promptley and has told me that keeping them in stock should be no problem. his website does a very good job of explaining them. if you have any specific questions, i suggest you email him. JUST LET HIM KNOW THAT KVRC SENT YOU. here is a link to his website.
