LS2 LS3 Clockwise rotation Billet Water Pump
This LS2 LS3 Clockwise rotation billet water pump was developed after years of doing LS conversions in our workshop for clients and in our own personal vehicles. The factory LS engine was designed to fit into engine bays such as late Commodores, Corvettes and Camaros and run a whole range of functions not always applicable when retro fitting into an old vehicle. Our LS water pumps are at the core of a range of products designed to maintain the performance and reliability of an LS engine swap without the messy appearance of using a modern motor.
Why is our pump different?
Our pump is designed around running clockwise, same as the old school V8 you always knew and loved. LS engines have a water pump that rotates in an anti-clockwise direction with extra idler pulleys to allow the direction change. Our clockwise rotation pump means the pump pulley rotates in the same direction as the crankshaft. This eliminates the need for idler pulleys and frees up space in the engine bay with the added benefit of having different water outlet options.
When used as part of our front drive kit it helps achieve a more compact low mount accessory drive system that is ideal for small cars and those with narrow chassis rails.
