SRP Piston Manufacturing Process

The manufacturing process for SRP pistons is a precise and complex operation that requires high levels of accuracy and attention to detail. The process is divided into several stages that include design, forging, machining, and coating.


  • The process begins with the design stage where engineers use advanced software to create a 3D model of the piston.
  • The piston design is carefully analyzed to ensure that it meets the required specifications and tolerances.
  • The design is then optimized to achieve the desired weight, strength, and performance characteristics.


The next stage is forging, which involves heating and shaping the raw material into the desired shape. SRP uses 2618 or 4032 aluminum alloy for their pistons, depending on the application.

  • The aluminum billet is heated to a high temperature and then placed into a forging press.
  • The piston shape is created by applying extreme pressure to the heated billet using custom forging tools.
  • Once the forging is completed, the piston is removed from the press and allowed to cool naturally.


The machining stage involves transforming the forged piston into the finished product, ready for installation. This stage requires high levels of precision and accuracy to achieve the desired tolerances.

  • The forged piston is placed into a CNC (Computer Numerical Control) machine for precise machining to ensure that the piston is within the required tolerances for diameter, height, and weight.
  • The piston is then subjected to a series of quality control checks to ensure that it meets the required specifications.


The final stage of the manufacturing process is coating, which involves applying a protective layer to the piston to improve durability and performance. SRP offers several coating options, including ArmorGlide, which is a moly-based dry film lubricant that reduces friction and wear.

Coating Option Description
ArmorGlide Moly-based dry film lubricant that reduces friction and wear.
Thermal Barrier Ceramic-based coating that reduces heat transfer and improves thermal efficiency.
Anodizing Electrochemical process that creates a hard, corrosion-resistant surface.

Once the coating is applied, the piston is subjected to a final quality control check to ensure that it meets the required standards.
