Fleece Performance LML CP3 Conversion Kits
Why convert your LML's fuel system from a CP4 to a CP3? Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms—resulting in costly repairs for owners when a CP4 fails. You can improve your LML Duramax's reliability and fueling capability, as well as avoid costly failure with Fleece Performance LML CP3 conversion kits. They provide OEM fit-and-finish features, like Fleece's exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and their valley feed line to support aftermarket lift pump applications. Fleece Performance LML CP3 conversion kits are offered with or without pump and the pump kits come in two different style pumps—a Bosch CP3 injection pump or Bosch CP3 pump with heavy-duty 10mm cam. Choose the kit that is right for you. All kits include: * CP3 to rail high pressure fuel line * High-flow CP3 feed and return fuel fittings * Preformed fuel feed and return fuel hoses * CP3 mounting adapter * Dosing injector distribution block, feed and return lines * FCA extension harness * Low pressure fuel feed line * Hardware kit

Pacific Performance Engineering CNC-Ported LLY/LBZ/LMM Cast Iron Cylinder Heads
PPE's CNC-ported LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine to eliminate any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE cylinder heads offer elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head's lifespan significantly. The cylinder heads also share the same heat expansion rate as the stock cast-iron cylinder block—no more blown head gaskets! PPE's CNC-porting process improves airflow, enhancing power, fuel efficiency, and throttle response while reducing engine stress and turbo lag. By smoothing the ports and maintaining wall thickness, these heads provide increased horsepower and torque without sacrificing reliability. Tailored to each specific head, the CNC machining compensates for casting variations, ensuring consistent and optimized airflow dynamics. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, cast iron cylinder heads from Pacific Performance Engineering are undoubtedly the best choice. Product features: * Specially alloyed gray cast iron liquid-cooled cylinder head * 5-Axis CNC-ported intake and exhaust ports for smooth, unrestricted airflow * Increased thermal efficiency compared to aluminum heads * Reduced noise and vibration, better ride * Eliminates head gasket scrubbing issue (blown head gasket) * Higher fatigue strength and heat resistance * Premium 21-4N, Stellite-reinforced exhaust valves * Fully nitridated valves, better abrasion resistance * Ready to install—comes with all valvetrain components, rocker arm dowels, and freeze plugs * Requires the use of LBZ/LMM glow plugs on LLY engines (sold separately) Important Notes: The valve seats of the PPE heavy cast iron cylinder heads are installed with an interference that maximizes the durability and lifespan of the cylinder heads. Such interference might not be optimal for extreme-performance applications where a significant amount of heat is created. For those applications, PPE suggests that the exhaust valve seats be replaced with higher interference (+0.006 in. to +0.008 in.) oversized exhaust valve seats (Nominal size 34mm).

With one touch, the remarkable TITAN Electronic Controller™ transfers fuel from the Travel Trekker™ to the vehicle's primary fuel tank until it is automatically stopped by the controller or the button is touched again. The controller monitors and reports the fuel level in the auxiliary system at all times. Controller installation is simple and never requires cutting into the vehicle's wiring harness which could affect the manufacturer's warranty. Fuel is pumped from the top of the tank which is safer and more environmentally responsible than gravity flow systems. The system comes complete with all necessary installation components and detailed instructions. Features Include: * Baffled to reduce sloshing * Electronic Controller transfers fuel * Fits under most tonneau covers * Lifetime Warranty * Does not interfere with in-bed hitches * Meets DOT FMCSA Title 49 Requirements * Pumps from top of tank

Titan Spare Tire Auxiliary Fuel Tank Systems
Introducing the game-changer for diesel pickup truck owners: Titan Spare Tire Auxiliary Fuel Tank Systems (STAFS). With an impressive additional 30 gallons of fuel readily available, these revolutionary systems transform your truck into a powerhouse on wheels, effectively doubling the fuel capacity of most diesel trucks. Gone are the days of worrying about fuel shortages on long hauls or remote expeditions. The STAFS ingeniously repurposes the typically underutilized space reserved for your spare tire, turning it into a valuable asset for extended journeys and demanding tasks. Imagine the freedom of having 30 extra gallons of fuel at your fingertips – it's like having your own personal fuel station wherever you go. Whether you're tackling challenging terrain, embarking on cross-country adventures, or hauling heavy loads, the STAFS ensures you never have to compromise on fuel availability again. Crafted from military-grade, cross-linked Polyethylene, the Titan Spare Tire Auxiliary Fuel Tank Systems boasts unrivaled durability and is backed by a lifetime warranty. Titan's electronic controller provides complete fuel control with a single touch. The operator has complete and total flexibility in managing how extra fuel capacity is used. The fuel can be held in reserve or transferred on-the-go as the need arises. The controller's illuminated user interface indicates the tank's fuel level and features a single-touch button that starts the fuel transfer sequence. With one touch, fuel begins transferring from the auxiliary tank to the vehicle's primary fuel tank, the pump will run for approximately 10 minutes, transferring 5 gallons of fuel. If the primary tank fills during that time, the pump will automatically stop pumping fuel. A great feature is that Titan's controller only requires a power wire and a ground. It does not invade the truck's wiring harness or computers. Its underbody location means that it has no impact on the truck bed's hauling space. In many cases where aftermarket custom wheels and tires are installed on a vehicle, they are not the same size as standard which means the original equipment spare cannot be used anyway.

The bundles include high-quality upgraded cooling components to replace items Mishimoto found to be the most failure-prone. Kits feature an aluminum radiator, silicone radiator hose kit, high- and low-temperature thermostats—plus other components (depending on the bundle you select). The Performance radiator features full aluminum construction with durable TIG-welded end tanks. In addition, it's designed with a massive two-row 2.2 in. thick core, which provides substantial improvements in cooling efficiency. The radiator hose kit is constructed from four layers of silicone with heat-resistant embedded fibers. This combination of materials provides substantially improved heat and pressure tolerance compared to the stock rubber hoses. In addition, the kit includes a CNC-machined aluminum quick-disconnect fitting, providing a considerable improvement in durability over the stock plastic unit. Rounding out the basic Essentials Bundle is a pair of thermostat sets; high-temperature thermostats hasten engine warmup, making it ideal for use in cold climates. The low-temperature thermostats have a lower activation temperature compared to the factory thermostat. Lower activation temperature allows coolant to flow through the engine earlier, reducing the risk of overheating in hot environments. Order the bundle with components preferred for your vehicle.
