Professional engine builders and racers have been winning championships and dyno shootouts with Ross pistons because of their near-perfect balance of strength to weight.

Now, Ross has raised the bar with its new Forged Side Relief (FSR) pistons, which are lighter and stronger than traditional piston designs.

Forged out of 2618 T-61 aluminum, Ross FSR pistons feature an inboard pin boss that accepts a shorter, lighter pin. The pin boss supports the skirt area and piston head with strategically placed struts and webs, resulting in an extremely stiff, yet lightweight, design.

Ross is offering its new FSR pistons for most popular small-block applications, including GM's LS and SBC engines. They are available for most O.E. and aftermarket cylinder heads and will accommodate bore sizes from 4.060” – 4.200”. FSR pistons are strong enough to handle nitrous, turbos, and supercharging.
