Fred, I bought the Koni FSD shocks from Brazel RV. They had the same prices as shockwharehouse and shipped the next day. I only did the front shocks 8805-1004SP1 (3/4" eyelet top and bottom). The rears are a different part number (8805-1005SP1).

I heard some negative reviews about shockwharehouse regarding very poor customer service when there was a problem (hard to get anyone, long phone wait times, etc.) so I went with BrazelRV.

     Thanks Mike, I will give them a try. I was really happy with the front FSD shocks when I put them on and now it is time to address the rears. Thanks again for the follow-up. Fred

A question for the experts: Somewhere I heard that unless a shock is leaking fluid, its working fine and doesn't need to be replaced due simply to mileage, for example. Please don't take this the wrong way, but  many who replace shocks go to great lengths to extol the virtues of their new purchase. Is there any quantitative, objective way to tell if replacing shocks make a difference? And no, I can't push down on the corner of my coach to watch for the rebound.......

What you say is very true.
However you can't say the shock is "good" because there's no external leakage. As a former mechanic, I can tell you I have replaced many shocks that looked okay on the outside (less normal dirt/scuffing) but once off the vehicle, were found to have no compression resistance or rebound.

 So you really need to remove them to test - but even then it can be hard to tell because without a "meter" of some sort, you can be sure they are all working evenly or within spec. I suppose you could try to compare a "new shock" to each of the old ones removed (but who's going to have a new shock to do that).

   I too am not a shock absorber engineer, however my Wife has the last word when it comes to porpoising. When she informs me she is about to "toss her cookies" and if I can't correct the situation, her rving days are done. All I can think of is perhaps the internal valving of fluid viscosity has changed or failed inside of the shock absorber. I put 4 Koni FSD (frequency selective damping) on the fronts about 2 years ago and my wife is all smiles. Now I noticed the rear is starting to do the same thing. Fred

Fred

There currently are two available on Amazon for $99.00 each with free shipping.  Perhaps you should snap them up before they disappear to someone else.
