LS Crank Pin Kit
Stock LS crank pulleys do not have any kind of keyway to keep the crank pulley from spinning on the crankshaft. This is fine for stock applications, but for supercharged, or high horsepower applications the crank needs to be pinned to prevent slipping.
Our basic crank pin kit comes with the following
1 Steel drill guide
1 Drill bit
4 Hardened dowel pins
1 Bolt to secure drill guide
Only 1 pin is needed, but we provide extras to do multiple cranks, or you can add an extra pin to your crank for peace of mind.
LS crank bolts are 1 time use only. We sell other kits with new crank bolts, and crank installation tools. We also offer crank pulley puller tools. Check out our tool page for these items you may, or may not need to perform this modification.

    Having read about the possibility of the balancer getting loose on an LS I decided to pin it to the crank. This kit makes it easy. The jig is just right to put the pin evenly between the pulley and crank. The drill bit is high quality and did not get dull.

    Works just as it should.
