ROSS Racing Pistons Releases Ford 4.6L Modular Stroker Pistons

El Segundo, CA – Ford 2 and 4 valve Modular 4.6L engines are extremely abundant having been in production since 1991 and 1993 respectively, fairly inexpensive and can produce excellent power. They are known for their high-revving ability, especially the 4-valve models when modified for racing.

Now Ross Racing Pistons has increased that performance envelope by offering forged pistons for 3.750” stroker crankshafts with 5.850” long connecting rods. This increased stroke ( .207”) will pump up low and mid-range torque which the little Modular really needs to be competitive in certain applications. Ross is offering the pistons in standard and .020” oversize bores with two compression ratios: 11.0:1 and a supercharger friendly 9.9:1. Both pistons are designed to handle forced induction or nitrous oxide.

Like all Ross racing pistons they are forged out of 2618 T-61 aerospace aluminum, machined to exacting tolerances on CNC machines that ensure flat ring grooves, precisely placed valve reliefs and dual pin oilers. Other standard features include a second ring land pressure accumulator groove, lock removal indents, pin fitting and radiused valve reliefs. High-strength piston pins and custom ring sets are also available from Ross.
