This propeller features a co-cured bonded stainless steel leading edge for erosion and FOD protection.  The two piece hub is manufactured from aerospace grade aluminum and is shot peened for durability and anodized for corrosion protection. Our Pitch Pin Hub System allows its users to set a broad range of pitches, using the system’s index pins to make adjustments. Simply loosen the hub clamping bolts, insert the desired pitch pin, set the blades against the pin, torque the mounting bolts and go flying!  The entire pitch change process takes less than 5 minutes.  Cessna 172 aircraft with O-360 or IO-360 engines will get four pitch settings total. This 2 blade propeller is approved for installation on the Cessna 172 aircraft with Lycoming O-360 or IO-360 engine already installed, including the all versions from the original through 172S.  The blades can be trimmed from the maximum 76″ diameter to 74.5″ diameter. Our package deal includes an 11″ composite spinner,  available with a white primer coat.  The package price is $9070, including propeller, spacer, bolts and spinner assembly, but not including the $250 STC paperwork fee.
