I'm deciding on a 6" lift for my 2006 HD2500. I've narrowed it down to Procomp and Tuffcountry. They're basically equivalent in price, with the Tuffcountry being about $100 more. The Tuffcountry is offered by Lesschwab while the Procomp is by 4WheelParts.LessSchwab ismore convenient (quite a bit closer to my house) and I like theidea of a more nationally known company if I have trouble down the line. The Procomp is comingwith better shocks (MX6 adjustable) and I believe was higher in price originally. Any thoughts?
