Ross Racing pistons are forged from 2618-T61 aluminum alloy and come standard with a ton of great features, including:

* Forced piston-pin oilers
* Double Spirolox pin retainers
* Valve pockets engineered for oversized valves and modern high-lift cams
* Fully CNC-machined skirts to deal with high heat and side loadings
* Radiused domes (on most applications)
* Balanced to +/- 2.5 grams
* Aircraft-quality pins

Due to the multiple variables possible with any engine combination, all compression ratios listed are approximate. To accurately calculate the static compression ratio of any engine, the following values must be known: Bore diameter, stroke length, rod length, deck height, combustion chamber volume, cylinder head gasket compressed thickness, and cylinder head gasket bore diameter.
