Maintain Your 6.6 LBZ Diesel  

  • Engine Oil & Filters - You can prolong the life of your engine by changing the oil regularly and following the manufacturer's suggested schedule. Get High-quality oils from well-known producers including Royal Purple, Hot Shot's Secret, and Lucas Oil.
  • Air Filters - Factory drop-in and high-flow aftermarket replacement filters K&N, AFE, and Donaldson can be used to replace the blocked air filter in your engine.
  • Fuel Filters - To safeguard the fuel system, choose OEM replacement filters or aftermarket filters.
  • Coolant - You can keep your cooling system in excellent shape by using premium coolants like Evans Waterless Engine Coolant, Mishimoto, and Hot Shot's Secret.  

Common Repair Parts  

  • Fuel Filter Housing - You can replace or repair your leaking fuel filter housing with supplies from Merchant Automotive and Racor.  
  • Crank Pin Kit - The factory dowel pin can shear off, causing the balancer to spin on the snout of the crankshaft. To avoid this, install the XDP Crankshaft Dowel Pin Kit XD33.
  • Tie Rods - Large wheels and heavy loads are known to put additional strain on the OEM tie rods, increasing the likelihood that they will break. Tie rod sleeves or stronger tie rods from BD-Power, PPE, Moog, and Cognito can be used to repair or replace the tie rods.

Popular Upgrades  

  • Cold Air Kit - Your Duramax's airflow will be enhanced using intake systems from S&B, Banks Power, AFE, and other manufacturers.
  • Tuner - To increase horsepower and torque, use Banks Power, Superchips, and Edge programmers and modules.
  • Exhaust - To reduce your truck's exhaust back pressure, install an MBRP, Banks Power, or AFE 4" or 5" exhaust system.  
  • Lift Pump - Since Duramax trucks were not built with a lift pump, adding one to your truck can improve fuel delivery. XDP carries lift pumps from top producers like AirDog and FASS. 

Popular Accessories  

  • Tonneau Cover - Your truck's bed contents will stay dry and safe with tonneau covers from Access, BAK, and Bestop.
  • Floor Liners - The flooring of your truck will remain clean thanks to WeatherTech and Husky Liners.
  • Running Boards - Getting in and out of your truck is made simple with Nerf bars from manufacturers like AMP Research and N-Fab.

Lift & Leveling Kits  

  • Lift Kits - Install larger tires and boost the ground clearance with kits from ReadyLift, Daystar, Rough Country, and other manufacturers.  
  • Leveling Kits - Cognito, Tuff Country, and Kryptonite kits allow you to level the stance of your truck. 

Appearance Upgrades  

  • Headlights/Tail Lights - Add headlights and taillights from Spyder, Anzo, and other manufacturers to your truck to enhance the style.
  • Wheels - Make your truck unique by installing wheels from DDC Wheels and Fuel Off-Road.

Towing/Hauling Products 

  • Hitches - Choose between fifth wheel, gooseneck, and drop hitches to find the perfect hitch for your needs.
  • Air Bags & Load Support - When towing, products like Air Lift, Timbren, Firestone, and others offer more stability and confidence.
