I installed a Prog 465-1162 on Sat. I had a Race Tech fork mod one month ago. I chose the Prog 465 because of my uses and price. Use: in about 8,000 miles over 2 yrs I have never adjusted the stock shock. I did have a pro set up F & R sag but never changed after that. I have never had a passenger. So, I figured once my new shock was set up, I would never use the adjustments available on the Elka, Ohlins, or Hyper Pro. After speaking to Prog tech guys and learning about the progressive rate spring, I further concluded I would not adjust it. I found a decent price on-line for it. The stock shock bottomed out on unseen dips, usually giving me a sharp pain mid back. Hwy 123 between Cayuse Pass on US 410 in Mt. Rainier NP and US 12 has so many of these hidden dips I can't or won't go the speed limit on that road. I tested the Prog shock on a nearby road with dips (W Lk Samm Blvd, Bellevue WA) and it did not bottom. I think this will be fine and a big improvement over stock. F & R cost $1,044.00.
