Whipple Marine Spring Loaded Supercharger Belt Tensioner

Whipple Marine Spring Loaded Supercharger Belt Tensioner

The Whipple marine spring loaded supercharger belt tensioner is a heavy-duty tensioner assembly used on many Whipple marine supercharger systems. Designed for compatible Whipple belt-drive applications, this tensioner helps maintain proper belt tension in demanding marine supercharger setups.

The tensioner features a cast aluminum body and is available with multiple finish options to match the application or build style. Available tensioner finishes include Natural, Gloss Black, Mercury Racing Blue, and Polished.

This product also offers pulley configuration options for compatible applications. Pulley options include No Pulley, 2.5" Guarded Pulley, and 1.875" Smooth Pulley. Because belt-drive layouts can vary by kit and engine package, verify the correct pulley option, tensioner finish, and application before ordering.
