i am getting a set of 2500 springs for $70. is that a good deal? and, what else should be replaced up front when i do it? i have a set of 4 RSX shocks coming. i will probably get a rear add a leaf before long, should i get a front 2" coil spacer? if i do that, will the RSX shocks fit w/ the 2500 springs and the 2" spacer? or when i order the shocks should i tell them its for a 2500 4x4? i have a 94.
