I installed the HyperPro Damper in the spring of '09. I had some issues ordering the damper for my '01 because the specs, at the time, did not show the earlier LT models. HyperPro said that it would fit.
For me the HyperPro damper was a 'no-brainer' because my OEM damper was leaking and it needed replacement. I had a slight wobble at very low speed (long story) and I did not know if this was the problem. As it turned out it was not the problem, the tire was defective. IMHO replacing a functioning
OEM damper with the HyperPro is not a cost effective purchase.
The effective price of the OEM replacement damper and the HyperPro, for me, was a wash, so the 'active damper' was a good fit. I did have some troubles getting the damper off but overall I see nothing different from OEM.
I adjusted it so that when it deployed it would be on the high side of the 'active' adjustment. Basically I believe that it might help recover from a racing type tank slapper by helping the rider slow the oscillations.
I don't intend to try it out or test it to see if it works.
I got a 'gold tone' damper. It sure looks as expensive as it was...
