Default Cobra Trailer Screw Jack

Ahhhhhhhhhhh....New to the forum? Do a search. LENGTHY threads on the hydraulic jacks used in Cobra trailers.


I replaced a totally worn out (circa 1985)Cobra screw jack with a Cobra hydraulic jack about 3 years ago, time split between midwest and west (desert), and havn't had any problem with leaks, etc.

I do make sure the valve is shut at all times except when lowering the ramp.

I also replaced the big Cobra jack actuating lever with a small butterfly nut. Not as convenient, but not as finicky either, and less chance of munging up the valve.

Bottom line - I love it. So much easier than a screw jack. Highly recommended.

YMMV, of course...

Cheers,
