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.

RAM Pro Street dual disc clutch kits are precision-balanced for smooth operation—and come equipped with a billet cover for optimum release length, a comfortable pedal effort, and a high diaphragm finger position for excellent high-RPM shifting capability. The sprung hub top disc absorbs shock and reduces driveline noise. Pro Street kits are available with your choice of an organic friction disc or a metallic disc. Organic disc models are capable of handling 500 to 800 hp; the metallic disc models can handle between 600 and 1,200 hp. RAM Pro Street dual disc clutch kits include a billet aluminum, SFI-certified flywheel with a steel insert that has sufficient mass to draw heat away from the clutch without distortion. Some kits are available with a steel flywheel. Order the clutch recommended for your vehicle and engine application.

RAM Force 10.5 dual disc clutch kits have a strap-driven floater plate and are precision-balanced for quiet operation. The sprung hub top disc absorbs shock and reduces driveline noise. Force clutches are available with your choice of a 300 Series friction disc or a 900 Series disc. The 300 Series organic disc models are capable of handling 500 to 800 hp; while the 900 Series metallic models can handle between 600 and 1,200 hp. These kits use a marcel spring—a thin, wavy device that helps to eliminate the go-or-no-go tendency that similar dual disc clutches have. RAM Force 10.5 dual disc clutch kits include a billet aluminum, SFI-certified flywheel with a steel insert that has sufficient mass to draw heat away from the clutch without distortion. Some kits are available with a steel flywheel. Order the model recommended for your vehicle and engine application.

Spicer Drivetrain Products front axle shafts feature an increased U-joint size that provides 25 percent higher yield strength than original U-joints. They offer unparalleled strength and longer life—the outer stub is re-engineered for added strength; improved snap ring retention reduces shock load failures; and material has been removed from the body and added to the yoke ears (to equalize deflection through the yoke and reduce bearing cap spinning). The axles are made from durable steel, with a micro-alloy improving their strength and a statistically controlled heat treatment ensuring proper hardness. Order the replacement model designed for your vehicle application.

ACT Mod-Twin 10.5 Extreme Street clutch kits are designed for high-powered street machines. These clutch kits unite uncompromised pedal feel, durability, engagement quality with very high-torque capacity by combining twice the organic friction surfaces with an ultra-durable sprung mono-drive hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process to provide a consistent light pedal feel. Steel-backed friction plates with high-quality organic friction materials deliver stable friction coefficient, good heat capacity and long clutch life. These friction plates uniformly transfer torque to the mono-drive sprung hub assembly, which extends input shaft life and reduces driveline shock from torsional vibration. The kits include a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung mono-drive hub assembly, floater, alignment tool and pilot bearing (where applicable). In addition, Mod-Twin clutches by ACT are also fully rebuildable, and replacement discs may be ordered separately. Product features: * Recommended for Street or Street/Strip use * Soft, progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise * Forged aluminum cover, mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions * Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances * 100 percent clamp load tested, balanced, and SFI certified

Advanced Clutch Technology (ACT) Mod-Twin 225 Maxx Extreme twin-disc race clutch kits are available in two styles—Sprung Race and Rigid Race—for a variety of applications, including many Subaru and Mitsubishi models. Here are descriptions of each: * MOD-TWIN 225 XX SPRUNG RACE CLUTCH KIT: Performs aggressive launches and smoother shifting in high-powered AWDs by combining twice the ceramic friction surfaces with an ultra-durable mono-drive sprung hub assembly in a completely modular design. Each diaphragm spring endures an exclusive 4-stage heat treating process, providing a consistent pedal feel requiring moderate effort. Puck-style friction plates with high-quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These plates uniformly transfer torque to a mono-drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung mono-drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). -- Features and details: Predictable aggressive engagement, increased pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise; forged aluminum cover, mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions; delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances; Drag, Road or Rally Racing; Applying tactical engineering to the Mod-Twin, ACT presents unique solutions to common tradeoffs found on twin disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity.
