nobody has one of these???
I was hoping one of the guys here would make the eco crank pulley myself, but if worse comes to worse I will ebay it!
As long as i can find one with the steel sleeve I'm all good.
I just want the lighter weight, not a under drive.
None produced have the steel sleeve, currently. The only one that use to have a steel sleeve was the unorthodox racing under driven crank pulley....and they are not made anymore. I can make one with a steel sleeve, but it will cost more.

not a whole lot of people run the rk pulley anymore.
they way over charge for something that you can just get on ebay for $30.
i would have to say mike's and unorthodox's are the absolute best quality pullies available to us LD9 boys.

We all need somebody to believe in something...
i got the MRZ ecotec under drive and the light weight alternator pully with belt for $265 with the belt put it on my car and it rubbed on the timming cover so took it off and then filed down the back of the under drive pully and put it back on did not rub any more made alot more power it really pulls hard at 4000 rpm and i have no problems with it at idle only when i got the radio and a/c on high and the headlights on then you will notice the a/c fan will slow down in the car and the headlight dim just a little but other then that i love it and with that and b&m shift plus with k&n filter and 195/60/14r in the front and 205/60/14r in the rear with no carpet and no spear and jack and only my driver seat but do have all side panels on i did pull a 99 grand prix gtp from start to end 1/4 mile with b&m on stage 2 and a 3000 rpm stall
