Had some **** typed, but deleted it because I'm not 100% sure of how the 2" shorter tender coil would work. I understand fully what the triple rate is. I was saying if it's too stiff with the current spring rates, if he goes to a 2" shorter spring on top, he might have to use a triple rate helper coil to keep his **** lined up if the shock extends past length of the springs between the lower spring seat and where the spanner nuts are set at to obtain correct ride height.
I'm no shock expert, but it's just hard to see why you would tune c/o's with spring lengths instead of spring weights. His original post states on his 14" shocks, both his springs are 14" each. And both the springs on the 16" shock, are 16" each. Not the typical rule of thumb of having your lower spring 2" longer than shock travel....thus meaning his spring lengths are already 2" shorter than the "norm" and you recommend taking even 2 more inches out? This would sound like his springs would remain so stiff in relation to his sprung weight, that:
He wouldn't be able to preload hardly any without raising ride height
His spanner nuts would be ran way down the shock body to compensate for the shorter springs.
Since his lower spring is not on the "long" side, being equal to shock travel, how will this affect his dual rate stop ring?
Again, maybe my understanding of this is wrong, that's why I'm here....to learn.
While his spring rates are not just heavy, there is still plenty wiggle room to go lighter on the front, and a little wiggle room in the back. I would suggest, getting it done and to go drive it around the yard first, before tweaking with spring rates or lengths anyways, though.
