Taller spring? What do you want to do with the bike? You can stiffen up the rear spring with some adjustments. If you want more ground clearance you wiill hve to get it from bigger tires. If you want a stiffer suspension becuase its valved too light for your weight then you will probably need a new shock and not just a spring.

You can only move the quad up so much, maybe an inch, with suspension spacers or taller springs. If the roots are getting hung up on the bottom of the quad then you need more ground clearance. Taller tires are pretty much the only way to get that on your bike.
