Electric Solenoids for Shifting

[Sky Captain]

Hey all.

I'm not sure if this is the proper sub, but here goes anyway.

Our team uses the AM Super Shifter gearbox. We normally use the attached pneumatic cylinder for shifting. However, this year we are trying to save weight by not including a pneumatic system, and AM also sells a servo based shifter for the gearbox. The problem is that the servo based shifting is slower and requires drivers to slow down and wait for 1.5-2 seconds to shift. Does anyone have any suggestions for an electric solenoid that we could use to shift instead? The cylinder has a 3/4" bore and a 1/2" throw.
