I would think so, my Fisher puts out 1700psi and there are lots of people on here running FEL plows made from truck plows.

Yes, truck plow cylinders should be just fine. The Meyers E60 pumps are set to 2500PSI.
And the crossover relief valves are usually set a tad higher. So when you bump a curb, while the pump dont see the pressure, the cylinders and hoses certainly do. They see a pressure spike.
Bumping into a curb will create substantially more pressure than the tractors hydraulics will deliver.
Which brings me to another point.....if you use a loader mounted plow, you really should use a crossover relief of some kind if you arent using a plow hydraulic unit. Otherwise you will blow lines and bend cylinders if you catch something solid with the corner of a blade.

They actually have their 1.5x10's on sale right now for $30 a pop. The 10" is what the meyers ST plows use. The 12" cylinders were used on the C plows.
Not sure what western, boss, et al use??
2500 PSI Snowplow Cylinders | Bore 1.5in. Bore Single Port

I read somewhere that the truck plows rant at 600-700psi, I did not understand how that would keep the crossover relief from letting the plow flop side to side as soon as you started pushing snow. It looks like the cylinders baileys has are good for 2600psi.
I am not sure if a cross over relief valve is necessary on a snow plow. Shouldn't the spring trip save the loader if you hit something. What about if it was a manual angle? It would not have any protection unless they have a shear pin.

My thoughts as well.
I don't have a crossover relief on my snow blade.
Any time I have hit something solid the trip springs trip.

Trip springs only help on a straight hit or on a bottom edge hit, not if half of the blade hits something. I'd imagine the leverage exerted on hitting only the outside edge on a immovable object could mess stuff up pretty quick w/o a relief built in.

the cross over is not designed to protect the tractor or loader or truck or whatever. It is there to protect the plow, angle cylinders, and hydraulic hoses.
Those of you without a crossover safety are tempting fate. On my truck, the crossover opens quite frequently. Like when pushing into a pile but you arent perfectly square, curbs, etc.
The springs only protect from something hitting down low. And sometimes even if you hit something low, but out on the edge, the plow wont trip if the blade is full of snow, rather the crossover protects you.
Think about the forces involved. These are only 1-1/2" cylinders. If the cylinder is 10" from the central pivot, and you are running a 7' blade, thats a 3.5x's mechanical advantage over the cylinder.
SO hitting an object with the edge with only ~1200lbs of force, and you are at 2500PSI in the cylinder. Hit somthing with more force than that without the safety, again, tempting fate, and it only takes on mistake to pop a hydraulic hose or bend a cylinder

I found another one for $200 which is better. Now I can replace the cyl. with new and I think I found a weld on skid plate from WorkSaver for $139. I will sand blast it an I hope I can be off and running for $5-600 for something like brand new.
