Hays Twister 3/4 Race performance torque converters are designed to be the perfect solution for your street/strip machine. Hays designed the Twister torque converters to be one step short of being a "Full Race" converter giving you the perfect combination of performance and affordability. Every torque converter is hand built, inspected and tested to ensure they meet the top of the line quality you expect. To ensure consistency and improve performance each converter is built for one transmission with one bolt pattern, meaning a lighter converter to maximize performance. High flow stators promote better cooling and heavy duty Torrington bearings are used to increase strength and durability. Not ready to go a "Full Race" converter, Hays is there for you with their Twister 3/4 Race torque converters.

Hays heavy-duty flexplates for high performance and competition engines are constructed from a thicker-than-stock steel plate. This enables them to withstand the stress of high-stall torque converters and high-rpm engines. While factory stock plates tend to crack around the crankshaft hub when punished under high-torque and rpm conditions, the thicker Hays flexplates can handle the force. These heavy-duty flexplates are supplied with a ring gear that is securely welded in place. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and SFI-certified under specification 29.1.

Hays Street 650 clutch conversion kits are designed to handle highly modified engines up to 650 hp naturally aspirated (600 hp for forced induction and nitrous combinations). The new 26-spline versions work in conjunction with a modern 5- or 6-speed transmission swap. These are true street/strip clutches for spirited high performance driving or frequent track use. The high performance dual-friction disc utilized in the Street 650 has an upgraded spring hub with heavy-duty damper springs to handle greater shock loads versus a standard damper spring. The disc features a sintered metallic friction surface and an organic friction surface. It does a great job at dissipating heat and fighting the slippage found in ordinary discs, along with providing the smooth engagement characteristics of a street-style clutch. These conversion kits also provide an upgraded heavy-duty pressure plate to round out the performance clutch. The Street 650 is a great choice if you visit the track often. Order the model recommended for your vehicle application. Features and benefits: * Upgraded damper springs deliver up to 30 percent more clamping pressure than stock OE clutch * Dual-friction disc offers the best of both worlds—smooth engagement and excellent holding capacity * All Street 650 clutch kits come complete with pressure plate, disc, throwout bearing, and alignment tool

Hays steel flywheels are engineered to handle extreme-duty applications and designed to take the punishment of today's high-horsepower engines. They are CAD-engineered and precision CNC-machined to strict tolerances. Available in weights up to 50 lbs. for specialized applications, most Hays flywheels are drilled with both the Borg and Beck and Long-style clutch patterns. Upgrade to a precision-machined and engineered Hays billet steel flywheel. Features include: * SFI-approved--legal for use in racing classes that require SFI certification * CNC-machined from certified billet steel for maximum strength and durability * CAD-designed for optimum performance and reliability * Offered in internal, external, or neutral (zero) balanced versions * Available for a wide variety of engines Note: When choosing a flywheel, remember that a heavier flywheel stores more energy. A heavy car requires more power (or inertia) to launch without bogging the engine and needs a heavier flywheel. Lighter flywheels create less inertia at launch, but will accelerate faster through the gears.
