Hays Twister Full Race Torque Converters
Hays Twister Full Race Torque Converters feature a custom-designed anti-balloon plate to stop any converter ballooning and swelling in racing situations. These torque converters are designed for use with a trans-brake and great for power adders such as nitrous, superchargers, and turbos. They're available with various RPM stall speed offerings to accommodate any mixture of modifications—including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss. Additional product features: * All Full Race Series converters are built, tested, and proven to support up to 1,000 hp * Designed to handle the extreme shock and abuse of trans-brakes, nitrous oxide, superchargers, and turbochargers * State-of-the-art spray welding process is used in select areas. Spray welding provides clean, strong, and consistent fusion while also increasing strength through hardening from higher process temperature * Each converter is hand-built and inspected in every step of assembly to ensure top-of-the-line quality * All Hays torque converters are internally welded, compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency * Heavy-duty Torrington bearings are used for greater strength and durability * Stators are chosen with high-flow vents and channels to promote cooling in heat-producing higher horsepower applications * Increased horsepower and acceleration due to a weight-saving, one-application design. Almost all Hays converters are built for one application to reduce weight, compared to a multi-bolt pattern converter * Full Race Series torque converters are offered in several different stall speeds for popular automatic transmissions.

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).

Titan Travel Trekker Auxiliary Fuel Systems
Now a new, better concept in auxiliary fuel systems: The TITAN Travel Trekker™ is made of military grade, cross-linked polymer--- tougher than steel and longer lasting than aluminum. Its durability is legendary. These tanks are routinely tested using state-of-the-art computer simulations as well as physical drop tests. Tanks filled completely and then dropped 30 feet onto a steel plate--- never losing a drop of liquid. They are so tough and well-proven that they are backed with a lifetime warranty. There are no welds to fail and if you ever accidentally run your gooseneck hitch into your Travel Trekker™ you will most likely find it springs right back into shape. Also, soap, water and perhaps a little furniture spray polish is all you need to keep your tank looking new. The Travel Trekker™ is baffled to minimize fuel sloshing and compact enough that it can be installed in full-sized pickup beds without interfering with most in-bed hitches and tonneau covers. 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
