Quick Fuel QFX-Series Carburetors

These Quick Fuel QFX-Series carburetors feature an all-new die-cast aluminum main body, which has a lengthened venturi section for greater midrange torque and better airflow. The annular booster venturis are precision die-cast with CNC-machined billet aluminum inserts, providing smoother and more refined air entry, a stronger vacuum signal, less turbulence, and improved fuel emulsion for better combustion. The Quick Fuel QFX-Series carburetors use red anodized billet aluminum CNC-machined metering blocks featuring 3-circuit metering (gasoline carburetors), changeable emulsion, idle feed, and intermediate bowl and feed discharge. Next, the die-cast aluminum fuel bowl combines high strength with significant weight reduction. They feature dual threaded fuel inlets and outlets and dual sight glass holes to easily set the float levels. The Quick Fuel QFX-Series carburetors feature Quick Fuel's external linkage with four different links to select the amount of primary throttle opening before the secondaries open: moderate progressive (25 percent), medium progressive (40 percent), full progressive (50 percent), and 1:1.

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. Features: * 1C cushioned ceramic—the discs offer a dampening layer between the two friction surfaces which is clamped together as the force of the pressure plate is exerted on the disc. 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.
