Fluidampr Harmonic Dampers

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

XClutch Stage 2 Clutch Kits

XClutch Stage 2 clutch kits offer performance upgrades for both street and track applications. Designed in-house, XClutch utilizes the latest ceramic technology in their Stage 2 kits offering either a cushioned or a sprung-style friction disc. They are mated with a high performance pressure plate and are recommended for vehicles requiring a higher level of torque holding and heat capacity.

This dampening along with a sprung hub offers drivability despite the ceramic friction surface. These kits are ideal for track cars that require some drivability or very high-horsepower street vehicles that require the added heat capacity of the ceramic friction material. * 1B sprung ceramic—these friction discs offer a sprung center to allow for drivability and are specifically designed for track use with minor street use. The kits offer great heat capacity due to the ceramic friction material and are available for a wide range of performance vehicles.
