Probe SRS Forged Pistons Mopar Dodge Plymouth Chrysler 440 and 496

Probe forged pistons for big block Mopar standard and stroker engines are a modern high performance design. Advances in CNC machine capability and the utilization of a "clean sheet of paper" method of manufacturing design has allowed Probe to create a forged piston line that is arguably a work of art. Probe's method of machining wrist pin bores provides the most accurate pin bore imaginable. Probe Forged Mopar 440 Pistons also feature the latest design innovations in ring land technology. The top ring land features radial anti-detonation grooves. These grooves knock the peaks off shock waves within the cylinder, reducing the propensity to detonate. The second ring land features our pressure equalization channel, which is a shaped channel that works by equalizing the pressure seen between the top and second ring with the pressure in the combustion chamber. This feature enhances ring seal, improving power, engine life and fuel economy. The Mopar 440 and 496 stroker pistons listed below all incorporate the advanced design of the current Probe Ind. technology.

In the past all pistons featured cam ground piston skirts to achieve the shape required to work in an engine. As with most things computer technology has provided us with the ability to improve upon this technique. Probe Racing Components is the recipient the newest CNC technology available to achieve the most accurate piston skirt designs and finishes in the industry. Further a complete "rethink" of the tooling and fixtures have allowed Probe to eliminate the variations caused by multiple setups. This all adds up to a better performing, stronger piston at a reasonable price.
