JE Pistons has announced that their popular SRP Professional Piston Kits will now includes piston skirt coating at no extra charge. Every SRP Professional piston kit already includes several features used in top level professional racing engines such as a lightweight forged side relief (FSR) forgings, high-quality wrist pins, and precision-CNC machined ring grooves. Every SRP Professional piston kit also includes a high-performance JE Pro Seal Ring set. This set uses a 1.2mm steel LS7-style top ring, a 1.5mm Napier (hooked face) second ring, and 3mm oil ring. SRP says their Professional ring package is far superior to the “cheap” ringset included with other piston kits and can provide up to 60 percent less wear. SRP also claims their Professional pistons and rings are compatible with nitrous and forced induction and have been dyno proven to provide up to a 12 horsepower gain and 20 percent weight savings over other aftermarket forged pistons.
