Pistons

Roush Aviation’s FAA PMA pistons are machined from Aerospace Quality 2618-T61 Aluminum Forgings. Using technology and knowledge gained from experience in motorsports and performance engine development, our pistons are redesigned from the original Packard and Rolls Royce Pistons to create a piston with better operating characteristics over the original piston design. All of our pistons now come standard with anodized piston ring grooves and domes. Additionally, our pistons can be ordered with our optional thermal barrier dome coating and / or optional friction reducing skirt coating. Pistons are available for 5.395”, 5.400”, 5.403” and 5.405” bore sizes.

Piston Rings

Roush Aviation’s FAA PMA piston rings are designed to operate as a set to work with our PMA piston. The ring set consists of a moly filled steel compression ring, a moly filled steel oil scraper ring, and a two piece iron oil supply ring. This modern ring package provides optimum compression sealing and oil control, with a reduction in drag from the original ring package.

Coolant Header Tank Pressure Cap

FAA PMA replacement Coolant Header Tank Pressure Cap. Our Cap contains a schrader valve in the cap to pre-pressurize the coolant system before flight or use it to pressurize a cold system to perform a maintenance leak check. Pre-pressurization of coolant system with shop air to 14-15 psi prior to operation will increase the boiling point of the coolant by 45°F (25°C). This will reduce the risk of having localized boiling in the cylinder head which leads to cylinder head cracking. Our Header Tank Pressure Cap is also available with an o-ring type seal, by sending your header tank to our FAA Repair Station for alteration. Additionally both caps are available with oversize threads to repair header tanks with damaged threads.
