How can a LIFT this Chinook rear end

[chin_k]

When I was shopping for shock replacement, however, I was persuaded not to use the version with the coil spring, and go with the regular shock. They said that the coil would interfere with how the MorRyde work. It maybe fine for the case where there is no MorRyde like in Flame's case.

Interfere how?

I have no clue, that's why I have to call them in the first place. The explanation I got was something like the spring may interact with the MorRyde, but they are not automotive engineers, and did not give me proofs with differential equation and spring constant, and damping function... I think the one with coil spring is meant for heavier load, like ambulance, but I think our RV weight more than a regular ambulance, isn't it?

My limited arm-chair thinking is that the spring from the shock and the MorRyde should only enhance each others, and at worst, the shocks may fail sooner than what it is spec'ed for, but they are relatively cheap component to replace. The important issue is how it behaves in the real world, and I am not a good person to be able to tell the difference if it affects the handling, etc..

I replaced my Concourse rear springs with 5,000# rated new springs from General Spring.
