To create forged pistons, manufacturers pressure-form molten alloys into basic piston blanks and then precision-cut the pistons to meet engine specifications.Continue Reading
The forged piston manufacturing process adds strength and durability to the products. General Motors Performance Parts created LSX pistons for nitrous, turbocharged and high revolutions-per-minute engine uses. The company also makes forged pistons to use with traditional Chevrolet small-block and big-block V8 engines.
Manley designed its Platinum Series pistons, which are available in three bore sizes, to decrease piston wobbling and to ensure that bores remain square.
Mahle deburrs its Power Pack pistons by hand and coats them with a Grafal anti-friction skirt coating to minimize piston noise, drag and wear.Learn more about Engine
