Iím not qualified to give the advice Iím going to give so take this with a salt lick.
Iíd replace it. 60% bent - by the time you get it back to straight, it will be weakened like a magicianís spoon bending trick. Even though theyíre only meant to stabilize (and not lift) the trailer, and even though the wheels (esp. if a double or triple axle) will take most of the weight, itís probably worth replacing with a fresh one.
Not an engineer here - just offering free advice worth everything you paid for it
