Metaltech LT medium or heavy springs

[Inv4drZm]

Thanks everyone- looks like I'll be getting the HD springs. Anyone run them with OME 60071L shocks? 15.25/26.5" seems like it should work without dropping the bumpstops.

Also, is everyone keeping the rear sway bar? I know it limits flex, but my 4Runner is a daily driver/kid hauler. Might keep it on most of the time and ditch it for burlier trails.

My brother has those shocks on his FJ. Freaking stiff. The FJ is short too so it feels like a constant front to back motion, the rear overpowers the front. He has stock weight in the back daily, just skids/sliders/roof rack if those count. Loaded down a bit more they do ride better of course. I wouldn't put them on my truck as a daily driver but they do have nice travel and are cheap. Noticeably stiffer than my 2.5" Icon rears and his previous 2.0 Icon rears.

Good to know. I have OME up front so I'm trying to match the feel of those. I currently have the 60020 rear shocks and they are firm, but not terrible. ARB lists a 60020L shock (14.9/26.5)- not sure how they cram that much travel in such a short compressed length.

i installed my MT heavy springs not too long ago. here is a pic unloaded, i would say the the heavy spring are definitely over 3inch unloaded. I have a measurement of 26inches from center hub to fender line. front coils were at a modest 3 inch setting, so the heavy springs def gave it more stink bug stance. tires in pic are some worn 295/70/17's. hope this helps those out on the fence. i'm actually swapping to MT mediums now because i don't run enough weight at this time, but will save the heavies for later. its not the ride that bothers me unweighted, its the rake that bothers me. Too much rear lift, and like Inv4drZm stated earlier, you have to jack the front coils up to the point of almost no droop to even get it close to reasonable (unweighted that is).

Thanks, Chankeye. That does look like more than 3”! How much weight does it take for the rear to settle down a little?

Your 4runner is looking good. It’ll be interesting to see how much lift you get with the medium springs.

I'm about 25" both sides. It's hard to get super accurate because my sidewalls bulge out so far.

This is mostly unloaded, just the bumper weight.

That looks perfect. 25” is what I’m looking for. How much does your bumper with swingout weigh? 250-300ish?

About 200, then the wheel/tire combo is like 80ish.

i've only had about 300 lbs in it and the back dropped less than .5 inches. i can see having full skids, steel bumpers, and being loaded with gear dropping it significantly, to the point of being perfect (to me). that's why i'm going to hang on to the heavy springs and run the mediums for now. thanks for the compliment though, i'll be installing the mediums today so i can get back later with a pic of what those look like.

which is exactly the height i want.

Here is the 2" on 35s with a 100lb tent on top loaded down with camping gear.

just under 2"

So after reading through it seems that it's totally fine to run these springs with the standard icon 2.0, part# 56505 shocks?

Would you reccomend the medium or heavy coils with 50# of tools, rear drawer system, 100# roof top tent. I'll be eventually adding a custom tube swingout.

go with the heavy, i swapped to the heavy and its been great with the weight.

Hi everyone,

I've searched for info regarding the new Metaltech long travel springs, but can't find what I'm looking for. Does anyone have hub to fender measurements for the next gen HD or medium springs?

I'm torn between the medium and heavy springs. I have full skids and sliders, roof basket, full size 33" spare, but no aftermarket bumper. I do have 200-500 pounds of camping gear fairly often.

I've been running standard Superflex springs and have been happy with those (other than wanting more travel), so maybe that answers my question....

Dear : Nothing to do with HD spring . because the description you mention above of your car is still light , the reason you still happy with the Superflex springs which is the lightest in the market , so the best thing you can do and deserve the experiment is to fix one of the progressive spring not normal stupid single rate spring specially when you are talking about 4wd , and the only progressive spring available in maker are Icon SKU : 52800 3” in normal and the one you mention Metal tech 2” SD-MT-GSJ-4050 medium why not heavy , because heavy when you drive in the city roads will give you harshly ride And hard bottom out And if you add icon Bump-Stop Kit you will be so happy ,:bravo:

If you're not going to run an aftermarket bumper then the 2" Medium coils will work fine. They'll be a little stiff unloaded, but perfect loaded.

I recently just moved to the heavy 3" coil to handle the weight of the rear bumper I put on after 2 years of the medium coils and no bumper. It handles the weight perfectly unloaded, and even better loaded.

Dear : Even if you return the heavy steel bumper your vehicle will be more comfortable ride . Never go with heavy springs , don't think because you fix steel pumper and few accessories you need heavy springs , totally wrong idea most of people have , heavy

is only when you bull heavy caravan , my friend
Heavy will damage some suspension parts in the long run .

Old thread but I'm hoping someone here might be able to provide some feedback on the Medium springs MT-GSJ-4050. I'm trying to build out my parts list for my lift. Considering 6112s in the front with an upgraded 650 lb spring. I'll be setting the snap rings to gain around 2.25-2.5" of lift. For the rear's I'll likely get 5160s, but I'm torn on springs. I've read a few posts with favorable reviews about Metal Tech. My truck is currently a bone stock daily driver, but I hit some forest roads and go camping a few times a year. Are these springs overkill?

Probably not the exact answer you are looking for, but here is my setup. I have 6112s up front w/ 700lb springs, on the 5th clip with a quarter inch toytec spacer on the tophat.

I had toytec superflex 2.0 springs that I swapped out a month ago for the Metal Tech Heavy long travel springs. I also have drawers that are probably about 80 pounds, along with my tire carrier setup which is probably another 100 pounds total. I have enjoyed having the extra strength in the rear for what I do and what I have back there. I haven't tested the MT springs out in Moab or any trails in Colorado yet since it is winter, but the ride has been good. I imagine with some or no weight in the rear the mediums will be perfect for you.

Something to note is that to get the true benefit of LT springs, extended shocks and bumpstops are needed, and to prevent rubbing when flexing, aftermarket LCAs and UCAs for the rear axle. I'm currently running Icon 2.0 shocks, which limits my travel, so I only have the springs right now. Saving up for the rest of the package. Feel free to ask me any questions and I'll try and get back to you.

I currently have the LT Metaltech springs and 5100's in the rear. I know that the springs are currently maxing out the shocks length. I can definately tell when going over bumps as the shock returns to full extension I think I can hear the thud.
[MENTION=266085]Caldizzle[/MENTION], are you still maxing out the 2.0 rear Icon Shocks with the LT Springs? And, if so do you think that the Rear Icon 3" springs would do the same? I just bought a set and was about to buy the 2.0 rears. But now not sure if I need something different.

Sorry if that all sounds confusing.

Thanks,

At the time, yes, I was maxing out the rear shocks still. I ended up having one blow and replaced them with LT basic Dobinsons shocks which have been doing great. From my understanding, yes, you will still max them out with the Icon springs, are they progressive rate?

The down travel of the shock will be the limiting factor depending on the spring. The "downside" to running a longer shock, is that you need to run bumpstop extensions as well. If you don't run extensions, the shock body will hit it's minimum length (maximum compression) before the bumpstop engages, resulting in a blown shock.

When I reached out to MT, the acknowledged that I was fine running LT springs with aftermarket shocks, but that I would only get the full potential out of the springs with LT shocks, which is why I picked some up when the Icon blew. I also picked up their 3" bump extension. I have been pretty pleased with the setup, and the guys at work have been impressed as well. The bumpstop extensions also save my fenders since I have gone to 35s.

 

[bripgilb]

First off... Epic Flex!

Second off... Are you running 35"s without a Body Lift?

Third off... the 3" icon lift springs I purchased are not progressive rate. But, now I'm having trouble finding them online. All I see are the 3" progressive rates.

I'm gonna call Icon and get their input on what to buy. Did you do the 3" brake line extensions too? Any change in the pan hard bar or lower control arms?

Also, are you still running the sway bar upfront?

Hey dude! Sorry, I'm not on here as often as I used to be. Thanks! I dig the amount of flex I have too haha.

I am running no body lift and 35s, you are correct. It works surprisingly well. I did grab the extended SS lines from metaltech when I went to taller coils. I also put on the EIMKeith PCK.

I had no front sway bar in these pictures, I've since also removed the rear.
