Common Repair Parts 

• Fuel Filter Housing - Merchant Automotive and Racor products are available to fix or replace your leaking fuel filter housing.  
• Crank Pin Kit - The balancer on the crankshaft's snout is known to spin when the factory dowel pin shears off. Add the XDP Crankshaft Dowel Pin Kit XD33 to prevent this from happening.
• Tie Rods - Heavy loads and large wheels are known to cause extra stress in the OEM tie rods, making them prone to snap. Fix or replace the tie rods with stronger tie rods or tie sleeves from BD-Power, PPE, Moog, and Cognito.

Popular Upgrades  

• Cold Air Kit - Intake systems from S&B, Banks Power, AFE, and other manufacturers can improve the airflow into your Duramax.  
• Tuner - Use Edge, Superchips, and Banks Power programmers and modules to boost horsepower and torque.
• Exhaust - Use an MBRP, Banks Power, or AFE 4" or 5" exhaust system to lower back pressure in your truck.  
• Lift Pump - Adding a lift pump to your truck can enhance fuel delivery as Duramax engines did not come with one from the factory. XDP has lift pumps from leading manufacturers such as FASS and AirDog.
