LS Pinning Kit
LS Crank Pinning Kit
Easily add two pins into your crank snout to stop the balancer or hub spinning on the crankshaft.
LS cranks do not have any keyway to balancer as standard.
When adding a blower the extra streese on the blower pulley will make the crank balancer or hub slip.
Adding keyways is the best way to fix this issue. This involves removing the crank from the engine and getting the keyways cut by a machinist.
This pinning kit can add the two pins with the engine still in the car.
The pins are not as strong as keys.
This is a cheaper and easier option to the alternative.
Not recommended on high horse power engines.
