only found on line

i'm updating my '47 street rod to use power steering and needed a dual alternator pulley to make it adapt to the engine...separate pulleys are not too easy to find...thank you for having a great inventory and in-stock parts to get it back on the road for the spring goodguys event..the car was a goodguys homebuilt pick at autumn 2013.and I love the award/plaque and display it at the shows...thank you,,,,, larry

A Little Off

All the dimensions seem to be right except for the belt groove width. It is claimed to have a width of .4000 but in reality has only a width of about .3400 It seems to fit the cheap $4 belts okay but if you try to use a nice high quality Gates belt only about 2/3 of the belt makes contact with the pulley. I was very disappointed with this product because the main reason for buy this pulley was for the width of the pulley grooves not because it's very shiny. I have bought pulley from other sellers with the proper dimensions before and was hopping the Speedway Motors company measurements where correct.

I moved my alternator from the left side of the engine to the right. There was some adjustment on the lower bracket mount to move it forward but not enough. After installing this pulley the belt alignment was perfect using the front one. Made very well and looks great.
