Magnesium Pulleys

Were there cast mag and billet mag pulleys built over the years?

rcd was making them, but in their new price sheets, their not listed so i guess they are not making them anymore. they were rediculous expensive when they were. up to 500.00 a pulley for the larger ones. buy used.

 

I hear ya and we've only ever purchased used ones. Saw one advertised as cast mag and it got me thinking as I will not run cast aluminum pulleys so should I also stay away from cast mag or is that the only way they have ever been made?

from what ive heard, some of the mag ones broke easy and wear quickly. i assume thats the cast ones, as i run billet ones, and havent had a problem yet. i believe the rcd were all billet, as you can imagine the price of a 6 inch solid round stock of mag would cost now! i do like how much lighter they are compared to aluminum, and the cost you can buy them used, why not?
