I have a '86 K-5, 305/700r4/208/31x10.5's with the factory tow package. The stock suspension is uncomfortably stiff. Every little bump or expansion strip is felt. The only non-stock items on the suspension are (please don't laugh) Sears-brand lifetime shocks, duals on the front, singles on the back. Am I just a wimp and this is normal for my Blazer? I'd appreciate any suggestions on this matter. Thanks. Jeep - Its what's for supper!
