  JE Pistons - SB Chevy
BRODIX -12 15° Dome & Solid Dome
Includes:
Pistons, Pins, Double Spiro Locks

Dome:
This race proven hollow dome forging is our newest design for sprint car applications. These pistons are designed to work with most of the new 15º chamber designs. These pistons have deep valve reliefs to accommodate oversized valves and long duration, tight lobe separation cams. Accepts 1/16, 1/16, 3/16 rings. These pistons utilize hollow
dome dedicated left and right hand forgings.

Solid Dome:
Similar in design to the above listed pistons except these pistons are manufactured with a solid dome. These pistons have the same deep valve reliefs to accommodate oversized valves and long duration, tight lobe separation cams. Precision CNC machined ring grooves accept 1/16, 1/16, 3/16 rings. These pistons utilize dedicated left and right hand forgings.
