2018 Spartan Shocks

[BBorgo]

Hi Stuart, your explanation of the air valve sounds right to me.
I was thinking that with large differences in weight, the bag would bounce more and cause the air valve to cycle open and closed more rapidly than the system could function, contributing to the pogo effect. The gas pressure shocks would exacerbate the pogo, making the ride height more critical. I'm going with you and Spartan.

when i complained of the bouncing, my local spartan shop checked ride height and it was fine....

tire pressures are adjusted to the load of the coach as well....

I believe that the fact that the re-valved shock exist is telling, I also believe that ride height that is wrong can damage shocks. Good that yours was checked.

Happy to report that On my own I installed the optional Bilstiens on the front, they are a very noticeable improvement, the dampening both up and down is great. IMO they should be standard equipment!

Did you install the Bilstiens or Koni. I thought the Bilstiens is the stock stocks?

Some time ago I installed the Koni EVO 99 shocks on the 20,000# Reyco-Granning dual steering box front axle. Much better than the adjustable Koni shocks I replaced. Well worth the cost. The EVO's use the FSD design internally but are designed for heavier rigs. My front axle has just over 18,000#'s on it.

Hi Stuart,

You have been busy.

So what were the old model numbers for the shocks and what are the new model numbers?

Cost for the 2 shocks and how long did it take?

Great work.

Update. Just got done driving 500 miles on the new shocks, 150 miles were twisty mountain roads with plenty dips. The new shocks make an amazing difference, the control over the dips was 100% better. They fix the problem as far as I’m concerned. As for the numbers I’ll have to look them up, they also can be found in the beginning of this thread. They are the Spartan upgrade Bilstein shocks.

Have you considered contacting Spartan to reimburse you?

Both Koni and Blistein were mentioned. The Blistein mentioned were the 60 mm shocks. I guess Spartan will know which ones are the better choice.

Ironically he's on the window sticker left of the driver's seat in my coach. I think we know what his day job is!
