• enalrging front hole for cables for 416C compatibility
• better cable routing around motor axis - added groove and nose as on V2 mechabox
• improved bearing bore drilling - more accurate bore and larger tolerances on bearing diameters
• enlarged grooves for the switch backdrop - only technological modification for RA
• enlarged cylinder bore
• Redesigned cylinder bore relief - created for maximum strength
• Redesigned cylinder mounting on 4 support points instead of full length- greater compatibility with multiple manufacturers
• enlarged piston groove for increased gearbox life
• Edge removal - previously a cable routing issue
• Removal of radius - previously a problem with bolt movement
• reinforcement around the cylinder in the rear
• spring guide together with mechabox in package to ensure full compatibility with retro arms piston
