Engine

The lightweight flywheel is a direct replacement for the original 2-piece flywheel and reduces the overall weight by 24lbs. The reduction in weight allows instant acceleration; lower race times, and enhances the overall performance of the car leading to a direct increase in driving pleasure.
Aluminum body, steel friction surface.
Fidanza aluminum flywheels are milled from high-quality 6061 T-6 aluminum, for lightweight with high strength and high-heat dissipation. The friction surface is 1050 high-carbon steel, secured with military-grade fasteners, and can work with any type of clutch material, including Kevlar, ceramic, sintered metal, and organic. The heat-treated ring gears are also 1050 steel, and are shrink-fitted and secured with Grade 8 button screws. These flywheels are SFI-approved.

The Lingenfelter oil cooler adapter is designed to allow the installation of an oil engine oil cooler on GM Gen IV V8 engines including the LS1, LS6, LS2 & LS3. The LPE adapter is machined from a single piece of 6061 aluminum and is then black hard coat anodized for additional durability. The adapter features -10 fitting for the oil inlet/outlets along with a port for the oil temperature sensor and oil feed line. This adapter was specifically designed to reduce oil pressure drop over other designs on the market, retains the factory oil filter location & includes gasket and bolts. Oil exiting the adapter is filtered oil.

The flywheel is the foundation of the clutch system, and because it is an energy storage device, also determines the amount of power available to launch the car. A heavy flywheel stores more energy as it spins than a light flywheel. If your engine and gearing combination requires more power or inertia to make the car launch without bogging the motor, you will want a heavier flywheel. Keep in mind, though, that a heavier flywheel will be slower to accelerate through the gears. A lighter flywheel creates less inertia at launch, but will accelerate quicker through the gears. In order to effectively use a lighter flywheel, you must consider the car weight, operating RPM of the engine, and most importantly, the gearing. Too little gear will cause the engine to nose over or ‘bog’ on launch.
RAM billet steel flywheels are recommended as a replacement for factory cast flywheels in high performance and racing vehicles. Cast flywheels are not explosion proof and can be dangerous when used in high performance applications at higher RPMs. RAM billet steel flywheels are CNC machined from certified materials and exceed SFI specifications. After machining, the flywheels are blanchard ground parallel to the crankshaft mounting surface ensuring minimum run out and the optimum mating surface for the clutch disc. Use steel flywheels in heavier drag race cars or for the best drivability in street driven vehicles.
Ram generally does not recommend aluminum flywheels for street use unless it is an autocross type of car. All Ram flywheels are surface ground and factory balanced to the engine.
