Each unit requires 2 wheels. Wheels are sold individually.
Comments about Wheel Assembly:
This is the second pair of polyurethane wheels I have purchased for my Precor EFX 544. Sportsmith is a reliable merchant and they always have these in stock. Installation only takes a few minutes and your ready to exercise again. I saved a couple hundred dollars by doing it myself and don't consider myself a handyman.
My only complaint is I wish I could have received a few more years of service from the previous pair of wheels. However, be sure to clean them as much as possible because it extends the life of the product.

we had no idea our old wheels were as bad as they were, until we put the new ones on. What a difference, quiet!
very quick ship
Comments about Wheel Assembly:
Product worked great. Not the same as existing rollers on other machines ... this one is white and others are clear; however great fit and works fine.

[...] one of the wheels starts making noise after half hour of operation and seems to be hotter to the touch than other wheel.
