Well there's no difference really, but the way its made and what materials are used can be a big factor.

In our pulleys we use lightweight and heavy duty aluminum to withstand the stresses that may be applied during peak performance.

So its really personal preference what company you'd like to go with.

Our kit has 3 pulleys versus other companies with one.

And then of course you have to add on the belt.
