60mm Big Bore Throttle Body Kit

60mm Throttle Body Relocate for Big Bores

Designed for the Big Bore and Stroker motor kits. Comes with a larger reed valve manifold available in billet or rubber.  Throttle body and manifold seal with an o-ring. The bigger engines gain throughout the entire power band from opening up the inlet to the reed and the bigger throttle body. This is the final step to getting the most out of your Big engine.  You can still make plenty of power with the stock or our smaller 52mm throttle bodies.
