Can you make the relief valve activate using bucket curl, up and down?
If you cain't, then one or both cyl are weak.

Are the cylinders hooked to anything when you are testing them for speed?
Could be a something in the lines or hoses causing more flow to one cylinder vs the other.

Do if you did the test with the cylinders not hooked to anything at all and the right was slow. Then swapped cylinders not attached to anything at all, and the right was still slower??
For now that rules out anything mechanical with the loader cause they werent hooked to anything. And would rule out the cylinder. Only thing left is the individual lines. You should have 2 lines coming off the valve. One for curl and one for dump. They should each go into a tee somewhere and get split between the cylinders. You need to look between the tee and the cylinder.
But I would also caution you to make sure you got all of the air bled out of the system.

Provided all the air is out of the system, they should be close. The one that has the longest hose after the tee could be a little slower. But fluid is going to take the path of least resistance. The loader frame should be rigid enough with both hooked up to overcome whatever small differences there are in the cylinders, provided they are both the same size.
Do the cylinders look like they are an identical matched set? or did someone change one at some point, perhaps to a slightly larger one. like going from a 50mm cylinder to a 2" cylinder??
Do you have any actual pictures and not the parts diagram of your loader, cylinders, and the part you are breaking. I am having a hard time getting a visual.

One more time, will the loader valve activate the relief when you use the curl cyl?
If so, then the cyl are performing up to the set relief.
If even one cyl is leaking, you probably will not be able to hit relief pressure, and you are working at the leaking cyl performance level.
If you have QD's, re-set them.
Did you try the curl cyl in the lift cyl work ports?
