Don't know your stroke length requirement, but these guys may be able to
custom build what you're looking for. PS - They ain't cheap!

Has anyone used 12v electro-mechanical/12v electro-hydraulic/manual
hydraulic linear actuators on a clam shell/alligator type trailer top. I
have bent 4 (SUSPA) gas springs in the past 4 months. Ordered what was on
the trailer when purchased. Ordered a pair of Bansbach Easylift gas
springs, but waiting for the SUSPA gas springs currently on the trailer to
fail before I put the new ones on.
If you have done any type of linear actuators and it is working, can you
forward photos? If tried and it is a futile effort on my part let me know,
I would prefer to spend my funds on other glider stuff.
