The best price is shox.com. I got mine for $500 even with free shipping. It made 100% better ride, and I run 90 PSI in front and 80 PSI in rear. Except for the big changes in the road conditions, you really don't feel any jars or thumps.
My front axels weights 7420 lbs. and on an F-53 chassis, the more it weights the smoother it handles. This way the springs and shocks move/work together and not just bounce you all over the road. It is well worth it. I was skeptical at first, but I bit the bullet and now I'm glad I did. Until you feel the difference, it is hard to have other owners believe in the difference.............
