American Powertrain Science Friction Flywheels

American Powertrain's Science Friction flywheels are available for most GM, Ford, Mopar, and AMC V8 engines. Their high-performance billet steel or lightened billet steel flywheels work best on the street for smooth performance—and for drag racing where the flywheel stores energy for hard launches. Billet aluminum flywheels are preferred for high-revving engines and in road racing where rapid rpm gain is essential. More than 50 models and configurations are available; order the flywheel recommended for your engine application. Features include: * High-grade billet steel or aluminum * Heavy-duty ring gears (with welded tabs on aluminum flywheels) * SFI certification is available on every flywheel * 20 percent lightening is available on steel flywheels * Double Blanchard-ground steel friction plates on aluminum flywheels * Aluminum flywheels have aircraft-grade riveted friction plates

American Powertrain ProFit Tremec TKX Manual Transmission and Installation Kits

American Powertrain ProFit Tremec TKX manual transmissions and installation kits put the power to the pavement with unmatched durability and versatility. Tremec has normally sourced their aftermarket transmissions from the OE side, such as the Magnum T-56 and the T-5, but this new design is made from the ground up as a strictly aftermarket transmission. Designed to fit classic muscle cars and customs, the TKX has a tighter, more streamlined case, and features 600 lbs.-ft. of torque capacity and are capable of engines speeds of 8,000 rpm with shifts at 7,500 rpm. The compact design provides clearance in most transmission tunnels without floor modifications, while case strength has increased from previous models with the new 3-piece aluminum housing and gaskets at all flanges simplifies installation and eliminates fluid leaks. Additional features include: * Designed with your specific vehicle application in mind * Available with multiple gear ratio configurations for compatibility for multiple applications with three shifter locations * Multi-cone synchronizers and synchronizer rings are made of sintered bronze and carbon for superior shifts * All gears are supported by caged needle bearings to reduce end play * Gears and shafts are made from ASTM 4615 grade steel and provide increased torque carrying capacity * TKX manual transmissions have 31-spline output shafts for added strength, built-in reverse light switches, and cruise control safety switches * The TKX also has separate GM and Ford case patterns and input configurations—with integrated GM and Ford transmission mount patterns * Installation kits include a driveshaft slip yoke made from cryogenically hardened steel, a polyurethane transmission mount, a steel roller pilot bearing, and a reverse light wiring harness
