Avoid catastrophic engine failure from a sheared dowel pin in your 2001-2016 GM 6.6L Duramax with the XDP Crankshaft Dowel Pin Kit XD331. From the factory, your Duramax uses a dowel pin on the crankshaft to hold the balancer in place. In both stock and performance applications, these dowel pins are easily sheared causing the balancer to spin on the snout of the crankshaft. When the balancer spins, it can throw off the balance of the engine and create harsh vibrations. Continued operation in these conditions will likely result in serious engine damage such as a broken crankshaft.

Eliminate the risks of engine damage and pin your crankshaft so the balancer stays in place with the XDP Crankshaft Dowel Pin Kit XD331. The Crankshaft Pin Kit includes a specially made jig so you so you can drill the crankshaft without requiring an engine tear-down, or a machine shop. Perfect for the toolbox of the at-home Duramax enthusiast, or a professional shop tech. The included drill bit allows for around 5 procedures to be performed before requiring a replacement. Each kit includes a jig, jig holding bolt, drill bit, pin, and installation instructions.

Application Notes:

• If using PPE, ATI, or a Super Damper, the counter weight must be removed before installing drill collar.
• This tool is not currently compatible with the re-designed Fluidamprs made in 2020 and later that have 6-bolt holes on the face of the damper.

• Engine Tear-Down Not Required
• Eliminates Factory Dowel Pin Failures
