I have used wood blocks 3-4 inches high in order to jack up my SUV's/ Pickups in the past. Is this bad practice? Or should I spring for the correct SUV/truck jack with 21 inches of lift?

I do of course use proper jack stands when working underneath the car. I prefer to use ramps whenever possible also.
