Ham and Quad strength radio

I read somewhere that you should be able to lift as much with your quads as with your hams. on the quad extension i can do 10 reps at 170 max, but only about 100-110 for 10 rep max and the ham curls. is that bad or is there any truth to that statement? thanks.

Ideally every one would want to have equal quads and ham strength, however ur quads get stronger, faster than you hams,i for my self can do 200lbs leg ext. but only like 120 on curls,
