Easy installation

I used this spacer to move the crank shaft pully out a little bit it was perfect . The belt lined up with water pump pully and alternator with no problem.it's like it's part of the of the pully things that are great about this item is that I didn't have to find a machine shop to make me one.things that aren't so great about this item is that it was made in Taiwan and engineered and designed in the USA the whole thing should've been made in the USA

.250 crank pulley spacer

I had to modify the center hole to fit in the harmonic balancer. I filed it out a little and it fit great. It definitely solved my pulley alignment problem.

Beatifully made part for the cost of it.

It fit and worked well for my spacer needed situation and I have a Bridgeport mill but couldn't make this part for what it cost me. I considered making one but the time I needed was used to do other things.
