Camoo Crank Pin Kit for LS/LT Engines CPK10SS — drill pinning fixture with hardened roll pins

Camoo CPK10SS is a precision drill-guide kit that lets you accurately pin the crankshaft and harmonic balancer on Gen III–V LS/LT engines to prevent balancer slip in high‑load or supercharged builds.

If you install a supercharger or build a high‑horsepower LS/LT engine, the crankshaft balancer can move under extreme torque. This kit provides a guided way to drill matching holes and install dowel pins that lock the balancer to the crank, reducing the chance of timing or accessory problems caused by slippage. The tool is machined for repeatable alignment, comes with hardened roll pins and a drill bit, and is finished for corrosion resistance.

How does this fixture help when fitting a supercharger?

The Camoo drill pinning fixture ensures the drill enters the crank and balancer at the correct location and angle, eliminating guesswork. It holds steady against side loads and threads into the balancer for a secure centering point.

• Provides a stable guide for straight, centered drilling.
• Includes hardened 1/4" roll pins sized for common balancer holes.
• Threads into the balancer for positive alignment during drilling.

What engines and applications are compatible with this kit?

This kit is made for Gen 3/4/5 Chevrolet LS and newer LT family engines — including LS1, LS2, LS3, LT1, LQ4, LQ9, LSX and LSA platforms in 5.3L and 6.0L variants. It’s especially useful for forced‑induction, stroker, or high‑torque builds where balancer slip is a risk.

• Fits LS1, LS2, LS3, LT1, LQ4, LQ9, LSX, LSA engine families.
• Works on 5.3L and 6.0L crank/balancer setups commonly used in swaps and builds.
• Designed for performance and supercharged engines where pinning is recommended.

What exactly comes in the CPK10SS kit and what are the materials?

The package includes a steel drill guide, a securing bolt, a drill bit sized for the dowels, and two hardened 1/4" roll pins. All components are made for workshop durability, with the fixture powder‑coated to resist rust and wear.

• One precision steel drill guide with machined threads.
• One installation bolt and one matching drill bit for pin holes.
• Two hardened 1/4" diameter roll pins for locking the balancer to the crank.

How difficult is installation and what tools will I need?

Basic mechanical skills and a standard engine bay setup are sufficient. You’ll need a drill (preferably in a drill press or a steady hand with a cordless drill), common hand tools to remove the balancer, and thread engagement to secure the guide.

• Requires removing the harmonic balancer for guided drilling.
• Use a steady drill or drill press for the cleanest holes.
• No welding required; dowel pins install through drilled holes.

Who is this for? Enthusiast mechanics, engine builders, and performance shop technicians working on LS or LT family engines who want a reliable way to prevent harmonic balancer slip in high‑torque or supercharged applications. It’s ideal for anyone doing an engine swap, adding forced induction, or assembling a high‑power street/track engine and who prefers a mechanical pinning solution over adhesive or interference methods.
