Great, heavy-duty springs. I like the ride quality and they go well with the 906 springs I installed in the rear of my 2000 4Runner. The pair makes for a nicely raked out stance, and the ability to carry heavy loads in the vehicle without sagging or negatively affecting the ride quality. They are stiff, though, so if you want something comfortable, maybe think about tall '99 springs instead. I have mine installed with Bilstein 4600 HD shocks, so if you're set on the 880 springs, and want something more comfortable there is always the option of just running a different shock. My two cents' worth...
