The "Hole Shot" timing spacer from Holy Performance - yet another great product from Holy Performance made exclusively for The Hungry Diesel.
The KSB in factory form has roughly 6 degrees worth of timing sweep - with adding a timing spacer that changes from 6 degrees to roughly 10 degrees. This sweep helps with efficiency and performance in the upper rpm band while maintaining more low end torque.
Note - these do not work with a THD Competition pump. Our pumps can be easily recognized as they are powder coated.
