I took the plunge and order the Complete Medium Duty suspension (4 shocks, 2 coils) from Rocky Road for $449 (part# OMEMONT91) and the OME front torsion bars for $236.65 (part# OME303011). Total price with shipping to the Boulder, Colorado area is $719.81. They said it should be here in 2 weeks. I will provide some feedback once I get it installed with the new tires.

If there are any installation gotchas, especially with the front torsion bars, please share. Thanks.
