Anyone on here running the OME 897 rear springs (Extra Heavy)

[SOcalTRAIL]

I'm running the OME 896's currently and think they are borderline on being too soft.... yup... a 320# spring is too soft for my rig so I was thinking about giving the 897's a shot with their 380# rate.

Curious to see if any fell T4R folks with pig trucks like mine are running the OME extra heavies (897's).

I know a guy that has the 897's on his RigI think it rides fine with very little weight in the rear. When loaded down (bumper, tire, gear, bikes, water) they feel great. I'll be switching to the heavies soon b/c of the bumper and the amount of water I usually carry in the summer months.

I can talk to him later. I do remember him saying that when he was in big bend driving through some rough terrain, it felt like he was on stilts even when loaded down.

[MENTION=74569]SOcalTRAIL[/MENTION] have you talked to icon about their new spring? I'm still curios about those as well.

I second this. Progressive springs are interesting unlike those boring springs you are running now.

Hmm, that would be awesome if you could post your findings if you get a chance to talk to him. Thanks!

I have... unfortunately they are too soft. The are a progressive / dual rate spring - the heavy rate on them is only 300#, the softer rate is somewhere around 180-200 if I recall correctly. They would be great as a step up from their standard 2" lift spring, but not enough. Now if they were something like a dual rate with a #350 / #280 rate, I would be on em like flys on you know what...:toilet:

Does CSS custom wind progressive springs? :evil:

That's a good idea, I will call them tomorrow and find out...

I am running the 898's and they are rated for 3" of lift with a constant 440 pounds. For the most part, I run zero weight in the rear besides a light weight jet ski trailer from time to time. The main reason I got these is so I would not have to switch them when I get a rear bumper in the future. They are a bit stiff, but not bone jarring in any way. It rides like a truck, like it should IMO.

I thought the 899's were the extra heavy springs for the 5th Gen??? The 899's are rated for 3" of lift with 880 pounds constant.

EDIT: Just looked on ARB's website. Looks like the 897 is listed under the 4th Gen 4runner as a 2" lift with a constant 660 pounds. So, if you want taller and super heavy springs, you could run the 899.

SO the 898's that you are running have the same spring rate as the 896's I currently have, yours give 1" more lift. Ideally, I would like to keep the truck where it sits, in fact I HAVE to seeing as how it barely fits in my garage as it is. The 897's are the same free height as the ones I run, just 60# more spring rate which, in the grand scheme of things is not a whole lot... not like the jump from the stock spring rate of 180 - 190 ish to the where I am now at 320#'s - Almost an 80% increase.

Yea, I think it would be a good move with the weight you are packing in the rear:clap2: I would not be worried about a harsh ride at all. Seems like it would only help you out with better weight management and stability.

Totally agree. I'm gonna give CSS a call tomorrow and see what they say about a super fancy progressive HEAVY spring, but its hard to look past the OME springs.... the price is just right!

Yea, love the affordability and quality of OME. Have you seen the "heavy" progressive rate springs from Metal Tech? They list the heavy spring specs here: FJ Cruiser/4Runner Rear Long Travel Coil Spring

Not sure if that would work for you, but it is another option.

 

[Keemonrunnin]

Socaltrail, so you carry roughly 400#+ constantly in the back of your rig? Now with a SW front bumper your total mpg=10/12 maybe 14 on a good day. If so,WOW. Hope this isn't your DD.

Thanks for pointing those out, unfortunately not enough...

Well... lemme do the math quick... Rear bumper without swing out was 110#, swing out, full size spare, recovery gear and ammo can are around 180#, Fuel tank is light (maybe 10 lbs with sending unit and fittings, 13 gallons of fuel (not all the time) @ 6.08 lbs / gal = 79#. There is 379# in just the rear bumper - I have the Gobi stealth, a full width "stealth" tool box up on top with a full set of tools, a high lift and shovel.... Not sure how much of that weight is distributed over the rear.... And then there is the rock armor - bud build beefy sliders and full front to rear Shrock skids add even more weigh. My rough guess.... I have probably close to, if not over 500# additional over the rear axel, depending on whether I have the fuel tank full or not.

Honestly, my gas mileage took the biggest hit when I sized up the tires to the 285's and added the Gobi rack. Even with everything I have on there and the new front bumper, I still manage 13 around town (mostly stop and go) and easily get 17-17.5 on the freeway. Just made a trip last weekend down to the desert with 2 other guys and a TON of search and rescue gear in the back of the truck and still managed over 15mpg average from my house, down to the desert 80 miles away, 5 miles up a dirt road, and home. The key is to drive slower than normal, any faster than 65 and you can watch the gas gauge drop...

Wow, that kind of weight easily justifies any extra heavy spring OME makes for sure. Sounds like you should get the 897's and call it a day.

Not to bad. I get about the same with less gear. I guess you can say I'm more heavy on the skinny pedal. Ya I'm trying to figure out what rear springs to go with myself due to my rear bumper should be coming in sometime soon. Another question for you. Are you running a scan guage reading your tranny temp? if so,have you notice any temp increase with the front bumper? are you running a tranny cooler? I know down in SD the temp can get a little on the warmer side and I notice you go out to the desert often.

Just thought of a question you may be able to answer in this situation [MENTION=74569]SOcalTRAIL[/MENTION]

What would be the downside to running a 3" lift spring rated at say 300# or 320# with your current ~500# constant payload. These springs are rated for less constant weight, but they provide 3" of advertised lift. With the 500 that you carry, it will obviously sit lower towards the 2" of lift you desire. Would this cause a less stable ride?

Would this cause a less stable ride?

What you are saying is kind of true in that the static height will end up to be 2", but it will still feel "softer" (going over bumps and such) since it's easier to compress a soft spring, than a stiff spring.

So basically let's just say you put on a real stiff short spring that nets 2" lift vs a much longer softer spring that also nets 2" lift. The longer/softer spring will bottom out much easier since it's that much easier to compress it the rest of the way down vs. the shorter/stiffer spring. If that makes sense?

Also, with the longer softer spring, your rear end will be much more sensitive to sagging when loaded down with lots of cargo. ie. extra 500 lbs of cargo will cause the rear end to sag 1" with the longer/softer spring vs only sagging 0.5" with the shorter/stiffer springs.

SO the 898's that you are running have the same spring rate as the 896's I currently have, yours give 1" more lift. Ideally, I would like to keep the truck where it sits, in fact I HAVE to seeing as how it barely fits in my garage as it is. The 897's are the same free height as the ones I run, just 60# more spring rate which, in the grand scheme of things is not a whole lot... not like the jump from the stock spring rate of 180 - 190 ish to the where I am now at 320#'s - Almost an 80% increase.

Shawn, if your currently springs free length are the same as the new ones you want and the new ones are 60lb/in stiffer, it's going to bump up the height a bit...what you need is a stiffer but slightly shorter spring to keep it all the same. Just a super rough estimate here, but I wouldn't be surprised if you gained 1/2" in height, do you have this much spare room overhead in the garage?
