Billet aluminum throttle bodies are CNC machined to exacting tolerances. Slabbed PTFE-coated throttle shafts are used with "low profile" button head screws for maximum performance. Our billet throttle bodies are assembled with PTFE bearing ribbons to minimize throttle effort and improve throttle shaft seal. These throttle bodies come with vacuum tubes installed, unless noted. (PCV 3/8", Manifold 3/16", and Timed 3/16"). All RQ-Series, XP-Series, and Q-Series Circle Track and Blower carburetors are equipped with roller bearing shaft seals for smoother operation and longer life.
