Details
JAmodified Pistons is the leader in forged Pistons on racing and high performance market.We combine light weight, high strength, precision machining and premium materials to design Custom forged pistons for a large variety of engines.
Additional Information:
- A 2 or 3 forging steps process yeilds a fine structural grain oriented in fibers in the same direction of the stresses
Pressure Groove for enhanced ring seal
Optimized crowns for efficient combustion
JA piston feature a unique PTFE coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance . This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances.
Custom piston:JAmodifed can produce pistons for almost all engines. If the parts you need are not within our standard, or you need pistons with different configurations, please fill in theCUMSTOM FORM and check PISTON CATALOG, we will have a design engineer to measure for you Customized.
