Thanks mike! You think there’ll be a variable spring for KDSS?!

No plans to make any shorter height variable rate springs

I'd be hard pressed to make a recommendation for what would work best for you. Is my rig really tall? IDK I guess. My hub to fender measurement in the rear is 23.75" unloaded. I don't think that's especially tall but it's all relative. The coils did settle bout 1/2" after about a month. Your rig is most likely heavier than mine considering the RTT and the drawers. IMHO this is where you just have to play around and see what works for you. Coils are pretty easy to sell if you don't like them and are relatively easy to install. However, the variable rate coils are much taller and are a bit of work to get in.
Again, I would really defer to @Crikeymike for advice specific to your setup. From the specs listed for your current coils and the 701V's it seems to me the 701V's are rated for slightly less load and are variable in addition to that so... maybe?

So this is normally the crossover from a 2" coil with the appropriate constant weight to a 3" coil with the Dobinsons options.

C59-325 - C59-675V
C59-327 - C59-677V
C59-329 - C59-701V
C59-331 - C59-749V

You're already running the C59-329 coils which are suitable for the weight you're carrying. I think you need to take a look at your shocks, as they might be affecting the quality of your ride.

Rear hub to fender at 2" of lift is usually right at 24", as an average.

I’m running c59-729. It is the same as 329?

Yes, just that 729s are offset height for kdss

Thank you for all this info mike!

Are the TRD Pro Fox shocks at all appropriate to be running with these coils? My rig is heavy enough now that it squats a bit and I'd like to bring that rear end back up.

I am always carrying a Gobi ladder, splitting axe, 100w rigid solar panel, auxiliary battery, steel molle quarter window panels and steel shelf, and cooler. I am also a photographer who routinely also carries ~100lbs of camera gear. It adds up.

I'd rough estimate that I'm about +350lbs over the rear when loaded up, and +250lbs daily.

looking into these suspension also. still haven't decided which one to go with just yet.

They are probably ok for 2" but I don't know if they're long enough to suit a 3" lift. You would have to get the specs of them or measure the amount of travel they have left from stock ride height. If the shocks aren't long enough, they will hit max extension often and wear out really fast.

Im looking for an option for my pig. I currently have Icon stage 7 with the curved Panhard bar for the KDSS, and OME 2899 coils. I am very heavy (Front/Rear CBI bumpers, Drawers, fridge, RTT, Gobi Rack, Etc. I started out with the Icon 2" and sagged, went to the Icon 3" Overland, and sagged. Swapped out with the DObinsons 701V, and those also sagged. I currently have the OME 2899s, but they dont flex well. What would my options be?


Thanks!

You got a build thread? I want to see this beast!

@Crikeymike - is is fair to say all of your variable rear springs will settle roughly 1/2''? I'm comparing the C59-675V vs C59-327 and if the 675V settles that much, it might not be as aggressive as it looks on paper.

No. The lifts heights I list are the settled height with the appropriate weight on them.

People make the mistake of measuring 5 minutes after installing and before the vehicle has settled and had a chance to break in at all. It takes on average 500 miles for coils to break in and settle.
