Avoid catastrophic engine failure from a sheared dowel pin in your 2001-2016 GM 6.6L Duramax with the XDP Duramax Crankshaft 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 this 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 Duramax Crankshaft 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.
Features:

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

Application Notes:
If using PPE, ATI, or a Super Damper, the counter weight must be removed before installing drill collar.
Warranty Info:
Products manufactured by XDP carry a 1-Year warranty against defects in materials and craftsmanship. The Warranty is Limited to one (1) year from the date of sale and limited solely to the parts contained within the product's kit.

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.
