Filler Neck

Leading professional drag racers have used small diameter, lightweight steel crank hubs in place of heavy stock dampers for years. They know that just like a lightweight flywheel, a lightweight crank hub allows the engine to rev quicker for faster engine response.

B&B offers water Filler necks in both steel & aluminum. The steel unit replaces a standard house outlet and accepts an OEM style filler cap. Our aluminum filler necks are machined from billet material and are available in standard filler cap design or AN hose design. The steel necks are finshed in gold iridite and the aluminum is natural finish.
