Cut And Coated Cast Pistons

 

Starting with the same piston kit as described above, the contour of the piston bowls are CNC machined and shaped for better fuel distribution and durability when using increased injector pulse widths and increased timing maps. 16.8:1 compression. Valve pockets can be machined upon request.

The tops of the pistons are coated with a thermal barrier to protect the piston from extreme heat. The piston skirts are coated with a dry film lubricant to reduce friction.

These are the perfect piston for today’s dual purpose “daily driven” performance truck.

       Available in the following bore sizes: std, +.020 and +.040
