What's the pro and cons for Stainless steel pulley (i.e. Alta) vs. Aluminum pulley (i.e. MINI-Madness)? :smile:

 

I don't think there is much functional difference for the various pulley materials for the 15% pulley.
Once installed whether the bolt on or press on type it does fine and there are no further problems or adjustments needed. The weight or durability of the steel vs aluminum is not a big concern.

Give Eric Savage at Helix13.com (he sells and installs the Helix pulley in 15% to 19% sizes) or Randy Webb at Webbmotorsports.com (he sells and installs various makes of pulleys) a call. (Edited: Caddman, any problems with materials?)

Just for note I did not have a problem with either materials at 15%.... just 19%

 

Did you ever post any pics or evidence of the "problems" you encountered?
