Nice truck & mods ! :rockon: Are the front coil springs linear rate or progressive rate ? Just curious.
Thanks! The front springs are linear rate, like Thurens. I'm not sure how the Carli and Thuren rates compare though. My springs were labeled driver/passenger side specific and it looks like that took care of the lower front driver side corner.

I found switching from Carli to thuren springs with the same shocks and valving the thuren was softer. And the thuren was taller by over and inch. 08 though

Yes, Thuren spring rates are lower than Carli across the board.

LOTS of different ways to skin a cat with the spring rates and valving, starts to make your head spin when you think you've finally understood something, then start talking to someone that does it for a living lol. I've never set up shocks on a truck this heavy that has varying loads and needs to be stable on road not just off road. As a rule of thumb on a dedicated prerunner like my ranger, spring rates should be as light as possible while supporting the truck at the desired ride height, and ride tuning is handled through valving in the shocks. Next week I'm going to install the Carli rear springs and remove the King shocks so I can disassemble and revalve (I'll run the stock Bilsteins for a few days) and I'll report back how the front/rear Carli springs feel vs stock springs with stock shocks.

So far, the Carli springs feel close to stock, but a bit sportier if that makes sense. They did increase height more than I anticipated though! before the springs, I had 2 7/8"-3" from the front rubber bump stop to the axle strike pad, thats gone up to 5" now. That's enough to make a huge difference in the ride off road since theres more room for the shocks to do their job of damping impacts before bottoming out. If anyone has some Thuren springs laying around, send them my way and I'll be happy to do a thorough back to back review/test with pics and mesurements :wink:

Here’s what the shims (valving) from a king 2.5 look like. This is the compression stack from my other truck.

Get the rear springs installed on the blue whale yet?

Sorry for the lack of attention in here! I did get the rear Carli springs installed. Unloaded, the truck sits dead level and rides nice. I've driven it with the new springs and Kings all around, as well as the bilstiens, and even with stock shocks, they're a definite improvement over stock springs.

What I don't like - the squat when loaded. With the tent rack, tent, camping gear, extra fuel, etc. the back end squats down about 3/4" -1" lower than the front. This has me considering a spacer in the rear, or maybe a slightly shorter spring up front, haven't quite decided yet, but I will do something differently as it's pretty annoying visually.

You have to go back a few pages because of the discussion, but check out the numbers in my thread from Thuren's rear coils. I think a spacer should solve your issue.

Well thats the problem with leveled trucks. You load them up and they look like they are saggingin the back.... well, because they ARE sagging.

Truth is, Carli and Thuren spring probably dont sag much more than the factory PW springs. The difference is the truck is level BEFORE the sagging, unlike a stock truck, so it looks much worse.

If you often are loaded, I would highly consider a spacer. Wont be level when unloaded, but...

Other option is air bags. I went that route and really like them.

Thanks Mike, I'll check them out. That'll be really helpful to compare apples to apples with where mine sits.

Olyelr - Yup, I went into it knowing the perceived squat would likely be an issue. What I wasn't counting on was the front springs providing as much lift as they did lol. Instead of gaining an 1.5" over stock like I was told, its more like 2.5", so that squat shouldn't have been as pronounced. (had 2.5"clearance to the front bumpstops stock, now its 5") The rear springs do squat a bit more than stock though. This past weekend we hooked the truck up to my parent's 30' airstream to move it around since my dad's truck was loaded down with furniture, and it put the back end down on the bump stops. The factory springs had maybe 1-1.5" before contacting the bump stops.

So did you gain some lift in back with the Carli springs then? At 2.5" of lift up front, you would have the sagging ass look if they were stock height.
