RetroArms Reinforced Piston with 16 Steel Teeth is a durable AEG piston with a Polyamide PA6.6 body reinforced with 30% carbon fiber and 5% molybdenum. The steel rack made of spring steel 14260 (54SiCr6) is CNC machined and subsequently hardened to a hardness of 52–54 HRC. The design is also suitable for setups with very strong springs.
RetroArms AOE spacer is designed to adjust the position of the piston head in relation to the sector gear. Correctly setting the Angle of Engagement (AOE) helps ensure proper initial contact between the piston tooth and the sector gear teeth and reduces unnecessary stress on the piston. The spacer is installed between the piston and piston head. It is suitable for servicing and precise tuning of an AEG gearbox.
It is used to adjust the angle of engagement between the piston teeth and sector gear in the gearbox.
The spacer has a thickness of 2,5 mm for a specific adjustment of the piston head position.
The spacer is installed between the piston and piston head during gearbox assembly.
A practical part for servicing, upgrading and precisely tuning an AEG gearbox.
