R-Lok 1-1/8” End Cap Nut to Rotate Engine
(For all serpentine pulleys and HTD pulleys above 21 tooth)
KRC’s R-LOK end cap includes a spacer that sits behind the end cap. This spacer is to be used at all times. If you are using a KRC R-LOK HTD or Gilmer crank pulley, the spacer included will be replaced with a rock guard that is included with your HTD crank pulley.
