[...]quality excellent

July 26, 2011
When used with a double lower pulley there needs to be spacers to help align and tighten the double pulley to the single pulley. Usually the double pulley is installed on the damper but that produced a significant gap between the single and double pulley. Had to install the single against the damper and then used washers between the double and single pulley. Perhaps there should be tubing spacers of the same metal to fill the void.
Pros:
  • Lightweight
Yes, I recommend this product.
