The highest quality 356 cast aluminum and state-of-the-art CNC machining are the reason for success behind BBK's performance throttle bodies. Each unit is then assembled with high quality BBK components such as an o-ringed shaft, double sealed roller bearings, precision stamped linkage assemblies along with factory quality fittings and connectors to ensure a perfect installation and life-long use. For mildly modified C4 Corvette engines use the 52mm Throttle Body; when engines are radically modified the 58mm Throttle Body is recommended. Fits 1985-1988 Corvette.

BBK Performance starts every year by creating a “wish list” of ideas for the year. They evaluate each idea in light of the company’s three main values: every BBK product must offer real-world performance gains, OEM quality and durability, and affordability for the DIY enthusiast. If a product doesn’t meet those criteria, then it’s sent back to the drawing board. They test every component for fit and then dyno-test vehicles to measure the actual performance numbers. Zip is a proud dealer of BBK products. Contact us to learn what’s new from BBK.
