I dont think Woodys 80 has a stinkbug look at all, and unloaded the coil set up has about 1.5" higher rear to allow its 440 lb constant load set up to bring the vehicle back to level at d=more than double that load rating.

I think your being disingenuous there a little.

We have 5 other coil variants that work with the 3" lift for non slinky applications in the rear for those who dont what the ultimate #slinkylongtravel set up.

We have the intermediate option for the lightly loaded like Woodys 80.

We have had no call for what you think your asking for, and have no issue with stickbug look as you are insinuating.

Ok, my mind is only on the Slinky long travel tapered lifts in mind.... was not thinking of any shorter shock version than the 28" longer shocks. I'm sorry for implying that you don't have options for the shorter 26" shocks.

I'm personally very interested in the 50mm front Patrol coil. If I knew the coil rates of 160/240 back when I ordered my lift I would of went 50mm rather than the 75mm front coils.

I will be getting these 50mm front Patrol coils for a future 40 body on 80 chassis project, but looking for a lighter duty rear long travel coil that is at least 21" in free height to run the longer rear 27" 2.0 shocks like the AC56512 with a rate of 220 to 250 lbs.
 
then the fronts you want the rear intermediate will be perfect.

We also made the front heavies so they can be trimmed up to 2 coils to fine tune the ride height too.
 
How much droop are you getting with the 75mm kit? I measured my current set up that needs to be changed and I'm wondering how this compares.

Also,
Which spring combination would be recommended for a HDJ81 with stout front bumper, winch, sliders, 35" spare? I don't want to be over sprung since it's mostly driven around empty so I think the airbag set up might be better for me when loaded up for camping trips
 
I run a 1HDT converted FZJ on the Slinky Intermediates. Have a Costa Fab front bumper, M8000, full belly skid and sliders. My 75mm setup measures 23" hub to fender. Shock length is basically 28" up front. That's what limits extension. I'm guessing the springs have a few inches left in them.

@Lumpskie

Is that measurement to fender or flare? My front is currently at 24.5" hub to flare and I love the way it looks. I removed the previous owners 2" spacers so my shocks are too long right now but I was wondering if the slinky kit would give me the same droop. I measured from the bump stop mount to the bottom spring perch and subtracted. Right now I'm getting about 5" of droop at 16." I tried to measure my shock length but I wasn't sure how they are measured. To the top of the threads at the top, or the mounting point, or the top of the body? Then the bottom apparently has an adapter. Measuring tip to tip my current shock is around 30"

I believe the consensus is to measure mounting point to mounting point. So for pin/pin shocks, measure about half way through. @GW Nugget can correct me here. Based on that assumption, it sounds like your shocks are really similar in dimension to the Slinky shocks. My measurements are hub to fender as I have no flares. @Box Rocket has the heavy setup and his measurements to the flare are about an inch higher than mine... 24" front and 24.5 rear.
 
If droop is the primary goal, 3-link the front and put some heim joint rear control arms in and some super long shocks and you'll get sweet RTI numbers.
For a bolt-on solution that has shown to provide the most travel but also will significantly improve performance on-road and off, I haven't seen a setup that does as well as the Slinky kits. Unless you're changing the front control arms/configuration, the Slinky shocks allow for the most flex I've seen from a bolt-on setup. For me personally, the flex is nice but it's not what I like most about the suspension. It's the ride and performance.

@vwluv10338 If I were you with the diesel motor and other weight on your truck I'd go with the 75mm heavy Slinkys. I think my 80 is similar to yours in terms of weight and is typically empty and the 75mm heavies are nice and I don't worry about sagging etc if I need to load up the truck for long trips.

FWIW, Jeremy Rohrs has an HDJ81 and runs the 75mm Extra heavies. Darren can correct me if I don't remember this exactly right but the extra heavies are not a higher spring rate but just a slightly taller spring to keep the same lift with more weight.

How's the noise level with the tapered wire fronts coils ? Or maybe better, how's the noise level off-road ?

Mine clunk from time to time on the road. Offroad, the do too but it doesn't seem as much. I heard the clunking goes away after the first few months.

That's interesting. I know what the cause is ( short spacing between the lower rate coils ) but I don't know what would cause it to go away after a few months. It would be good to hear more reviews from guys who have had them on their rigs for a while.

I figured that it was probably the surface of the powdercoat sticking to itself a bit. I believe that I read @woody mention that his were noisy when new as well... and, maybe @GW Nugget ?

Mine already seem to be doing it less than they did a week or two ago. I've only got a couple hundred miles on them but plan on taking the 80 on a road trip to NY next weekend. That should put some miles on.
 
Yes they make a Slinky sound.... Hmmm... maybe that's the origin of the name. :hmm::meh:
That said, it is very quiet though, my rig makes many other sounds, it's not a big deal.
 
Yes its a powdercoat thing more than anything, and it goes away quickly, especially on heavy trucks.

You might get the odd "dong" noise odd times turning up a drive, or smashing up a kerb cutting a corner at speed, but not much at all really to be honest.
 
I might very well be the heaviest rig running a slinky suspension (Extra HD rears) and I have never noticed any clunking on or offroad.
 
Mine have always been quiet until recently. The left rear coil seems to have developed a bit of a "rattle". I'm guessing two winds of the coil are close to each other but not in full contact so its rattling as they bump together. I can replicate it by hitting the coil with my hand. Maybe I need to put a little weight in (or out) to solve it. It's minor but something I've noticed.

Up there but not quite :smokin:

Unless you over 10,000 lb ?
 
Question for @Box Rocket @GW Nugget @AutoCraft Aus

I was testing some flex on my rig yesterday (75mm intermediate Slinky stage 1) and took a look at my rear shocks while flexing. I noticed that my shock had about 2" of compression yet while my extended rear bump stops had about 4" left. I didn't grab a picture, unfortunately. I mounted my 79 series bump stops directly to the frame and there isn't anything mounted to the top of my axle. Is my setup typical? If so, is the expectation that the 79 series stop will bump the axle prior to the shock bottoming out?

Here's the only picture I have. You can see the bump stop I'm stalking about:

Thanks for the help.
 
Yes, I don't have a picture of them to show but they work just fine. Just to note it does add 1" to 30mm over stock bumps.

Should be fine. Mines the same.
