SRP Professional pistons are advanced lightweight FSR forgings that offer superior strength and are up to 20% lighter than traditional equivalent pistons.

SRP professional pistons come standard with high-performance skirt coating and low drag performance piston rings. Additional features include a forced pin oiler for increased wrist pin lubrication, pin fitting, and double spiro locks. CNC machined ring grooves accept 1/16, 1/16, 3/16 rings (sold separately).
