What's new

Anyone explored replacement leaf springs?

So its been awhile, anyone try out some different leaf pack solutions with deaver or icon? After going offroad a bit with the tremor and halo lift 2.5's im feeling like the springs are the weak point even with airbags, its causing me way too much body roll going up mountain passes unless I have bags pumped up to 50psi. Even then I still feel quite a bit of roll. Im still trying to troubleshoot, but its either the Elka's are too soft at the low end of the valving or the springs, but im leaning toward the springs.
Our OE springs to suck but body roll is generally anti-sway bars. it definitely depends on the extra weight on the truck and where it is. for my rig, I'll be adding a light rear asb in August when I have time.

What suspension did you end up using for the rear for the weight of your canopy and gear?

the heavy dampning bilsteins. They're on my Mountain Yak snd build resources page (I'm pretty sure). @Cranbery just posted he got the stage4 kit from Icon. Not sure it's installed yet but it seems it'll be soon'ish

Found your build page, saw you hinted at something in the works instead of the L84HD's. What did you end up working on for the leafs?

I have a 5 link that needs to be tested out but I think I'm going to swap in the Icon before I completely rearrange my truck
 
Nobody tried the Icon springs? Seems like a great option, stock, +300lbs, or +700 lbs option (while maintaining factory height).

It’s either Icon or RAS for me. Use is an overlanding platform with a pop up camper. Probably will have 600-800lbs in the bed at all time. Thoughts?

5 link? Dang go big or go home! :LOL: Are you talking about the Icon leaf set or shocks?
There are a couple (including me) who have bought or plan to buy the Icon leaf packs. IIf I pull the trigger, I'm planning on option 3 (850#) with no drop shackles.
 
I know this is an older thread, but just kinda wanted to see what the decisions were and thoughts on how everything turned out. I ask because I've been concerned for a while about the sagging rear suspension (the rear leaf springs run fairly flat instead of curved as I would expect), and my mechanic mentioned it to me today as well, so I'm finally dealing with it.

I don't run all that much weight in the back (there is the Decked system and a SmartCap with a few resident items, but likely under 500Lbs, so I wouldn't think the springs would sag so much- I'm concerned something is broken or bent (I'll look at it as soon as it dries out outside), but the mechanic didn't mention anything broken or bent when he was under there today for the oil change/wheel balancing).

I do use this for some offroad, which could get to more complex stuff (hopefully not much more than a 3 to 4 rating, but 5 is possible) in the disaster environment (and just wheeling) so I need to have the flex and articulation, but at the same time, the truck needs to be able to carry 1000+ Lbs of gear and equipment.

I know there was talk about Deaver making something Tremor specific but I don't seen anything from them on the website beyond 2022 for the Raptor.

Part of the question, I guess, is whether this is a design/warranty-type issue or an issue of too much or constant weight.

I should also add that I do have the tow package, and I also realize that there are products like RAS and airbags, which are a possibility, but it just doesn't seem like I should need something like that with the amount of weight I'm carrying. I'd also prefer a simpler setup, running just appropriate springs instead of using aftermarket add-ons which could be a liability or failure point.

Thanks!
 
I'm running the full icon pack without the drop shackles. Squeaky as Hell but a significant improvement over the stock with ras
 
Thank you for the responses!
DistinguishedTremor, Yeti and others with the Icon leaf springs, did you have to buy Icon's rear shocks and their hardware kit? The Icon website says that those are required, but my shocks are fairly new (the Halo 2.5s) and I'd hate to buy another $1000+ set of shocks on top of the $1000+ for the springs.

I'm currently running the eibach 2.0 shocks (until spring) and will be replacing them with a 2.5 (probably Halo'ish). I have two concerns for the Icon shocks.
while I love digressive shocks, my use case makes high/low speed compression adjustment more attractive. Second is who in the heck wants to grind up their brand new and very expensive shocks? That all said, you may need to run a different shackle to make sure it all fits well.

You can buy them “a la carte” just send them a message for all the part numbers
I just didn’t want a super high rear end so I dropped the pack 2” and got about 2” of lift with the add a leaf so it was basically back to stock height with my added weight.
I greased my leafs and haven’t heard a peep! If I do I will just drill and tap a grease nipple in there and grease them when they squeak like my front a arms
 
Thank you both!

Now I just need to determine if the flat-running springs are a safety issue that I need to deal with (and spend $$ on) or if it's just a looks/performance/convenience type of thing, which I can put off even longer. :ROFLMAO:

I had the icon pack on their with no weight in the back and stock right height (icon pack with drop shackles, no add a leaf) for a few weeks and it was probably one of the best riding rear ends of any truck I have ever had. It was strong when towing and road like an absolute cloud on the freeway. Gravel roads it soaked up the bumps really well and it flexes really well, barely nicks the exhaust at full droop though.
Night and day to stock and I reccomend it!
That’s a pretty good reason to make the purchase!! 😂
 
I've sure FoMoCo made the spring rate soft as most people don't actually use their trucks for much more than groceries but those of you who do load it up, I'm sure have been unimpressed. 1200# pounds in the bed below and it was riding way lower than I would like. I am thinking about reaching to Deaver for some options but just wondering if anyone else has explored this yet? I don't mind throwing some money at this problem. Airbags, helper springs, roadmaster active whatever are cheap bandaids that don't truly solve the problem since they all have their drawbacks. I'm wanting a progressive, linear that does not limit articulation. I run around 80% of the time with not a lot of weight in the bed but not uncommon to put this much, and more, weight in the bed. I've got a three+ hour trip Friday with a max-GVRW load for instance.

I'm in the same boat. I have a truck camper top with my gear and the top it's probably 600 lb. I put the RAS system in that helped. I had air springs on my last super crew they work but the ride sucked. I also have a hidden winch in the front of my tremor, and pull a 10,000 lb dump trailer occasionally. Waiting for someone to make a complete kit with front rear springs and some nice reservoir shocks.

I forgot I started this thread. I have installed RAS and have been super happy with that solution. More stable at speed, less sag when I tow or haul. Basically sits level. This is the HD kit set at 24% with a 3/4" shorter block than stock.

I think the icon pack would work well I replaced the 3rd spring with the add a leaf as I didn’t need too much extra weight for daily driving. But the other option is to add the add a leaf into the progressive pack this gives you 1” over stock height with 850 lbs constant load.
I have Icons rear reservoir shocks and love the adjustability
I run them on 1-2 everyday and when towing I turn them all the way firm. My trailer weights range from 3k-10k and it works well but I only haul short distances of maybe 30 miles at a time between drop offs.

I'll have to check out that option. Nice boat! I'm looking out at the lake right now that's half frozen and won't be able to get out till April.
