2 inch springs? .. with my 5100s.. OME?

since i probably need to get another alignment to adjust caster.. (thanks harper).. i figure now's a good time to get springs to go with my 5100s for a lift

i wanted to make sure and double check before pulling the trigger

front:

OME 884 springs with my 5100s set to .85 and stock top mounts.. wheelers show them as a 3" lift? is this accurate?

rear:

OME 889 springs which according to wheelers is a 3 inch lift.. are the 5100s rears able to handle a 3 inch lift?

i'm actually looking to get a 2 inch rear spring and 2 inch front spring resting on 5100s at .85 but it doesn't seems like OME have something like that

I have 5100's set to the 1.75" setting with 1.5" SAWs in the rear and it sits level when measuring the front and rear of the frame. I believe the rear bilstein's will only support 2" of rear lift.

Thats very nice but im looking for rear springs allow me to set 5100 to 2.5 in front and not be nose high...

How accurate are ome spring lift claims. Does ome 895 really give 2 inches in rear? or how bout toytec superflex .. it says 2 inch lift also..

4ShoreRunner,

Do you have any side view pictures of your T4R with this suspension set up but before you added the weight in the rear end with the awesome tire carrier setup? Your suspension sounds like what I am looking for.
 
anyone else can chime in?

totally confused now as some say OME 895 (2" lift) springs are for 4th gen only???

wheelers only list OME 889 as an option for 5th gen and that's a 3" lift spring?

the same OME 884 for fronts give only 1" lift on 4th gen and 3" lift on 5th gen!!!!??

that's according to the ARB website..

i would hate to put springs in the rear that is too short or long with front 5100 set to 2.5..

hellppp?

I'll try not to hi-jack this thread too much and answer your question while also providing input...

The 1.75" setting visually levels the truck. The measurements from my wheel hubs to the top of the wheel well were dead on the same w/out my 1.5 inch SAWs in the rear; HOWEVER, keep in mind that the rear wheel well is cut out higher than the front.

So, in my opinion, the "level" look that most strive for is actually an optical illusion because while the tops of the fenders may be level, its actually a little nose high when measuring from the frame.

I was happy with the 1.75" setting w/out rear springs, but as soon as it was loaded with people and cargo the sag was apparent. I knew that throwing the tire carrier would add to this so I went ahead and got the 1.5" SAWs to compensate, and it did so perfectly.

Long story short - I added the SAWs and the tire carrier at the same time....no shots of it w/out the added weight. The tire carrier probably comes in around 150 lbs. Sorry!

Also about the OME's, there is no reason why they shouldn't fit our 5th gens, if they aren't listed its probably because they were never tested, but don't hold me to that.
 
Silversx:

I was told by a guy at toytec that the OME springs don't work well with 5100's set to any lift height. (but will be fine at the 5100's no-lift setting obviously). The OME's don't have enough coil winds to handle being pre-loaded on 5100's set to notch 2,3, or 4. They loose their smoothness and progressiveness.

I currently have stock springs with 5100's all around with the front set at .85. Very happy and looks more natural, it's fine for me but I can understand someone that wants or needs more lift.

Whatever you do I believe your goal should be to add 1" more front lift than rear. Ex. 3" front 2" rear, or 2.5" front 1.5" rear.

I would have to say that my setup feels balanced for the most part but I can tell that the front spring rate is slightly stiffer than the rear. I have a good sense of suspension and handling dynamics, most people wouldn't notice. If I had the front 5100's set to 1.75" with the stock rear springs, it would be really out of whack. Way too soft in the back compared to the front, almost dangerous.

I had thought about the SAW rear coils at 1.5" and setting the Bilsteins with stock springs to 2.5" of lift. Height wise this would be about perfect. The only question mark is how are the spring weights changing in regards to % increase over stock front vs. rear. It probably would be close to good but no way to tell until someone gets data:

The question becomes, with stock springs, what is the spring rate of a 5100 set at 1.75" or 2.5" of lift? And what percentage over stock is that? And when pre-loading the stock springs that much how smooth and progressive is the travel going to be?

We should be careful that the % increase in front spring rate closely matches the % increase in rear spring rate. With the 5100's set to 1.75 or 2.5 it's a guessing game.

Here's some data I compiled: (all lift heights based on 5th Gen not 4th)

Front
Stock oem springs are 500lbs
OME 883 2" Lift 590lbs rate, 18% stiffer than stock
OME 884 2.5" Lift 590lbs rate, 18% stiffer than stock
OME 885 3" Lift, 590lbs rate, 18% stiffer than stock
OME 886 3" Lift 650lbs rate 30% stiffer than stock

Rear
Stock oem springs are 180lbs
SAW 1.5" lift 213lbs, 18% stiffer than stock
OME 895E 2" lift 260 lbs 44% stiffer than stock
OME 895 2.5" lift 260 lbs 44% stiffer than stock
OME 889 3" lift 260 lbs 44% stiffer than stock
Superflex 2.5" lift 218 lbs 21% stiffer than stock

Looking at this data, the 884's in the front and the SAW in the rear would both yield a 18% increase in spring weight and would lift an optimal 2.5/1.5. The other combo that sticks out is the 885 front and superflex rear for a 3/2.5 lift. I discovered that all of the OME rear springs are darn stiff! Great for guys that haul stuff a lot or that tow or have rear bumpers or fridges, etc. For me though, I would want the percentage increases in spring rates to stay balanced front to rear. Hope this helps.
 
OOPS! Another thing...

I took Harper's advice and had my caster set the most the guy could get it at, which with the Bilstein 5100's set at .85 was approx 3.8/4.0.

HUGE difference. It's a definite must-do.

Problem is that the alignment guy said that was the most he could get on mine.

If you had any more than .85 inches of front lift you are going to need to get UCA to get close to 4 degrees of positive caster. Harper has them.

I can't stress enough how much straighter, less suceptible to cross winds, and just how much better the 5th gen drives with 4 degrees caster. It's a big deal.

So if you want to do a 3/2 lift plan on getting lightspeed UCA. PM harper for the best place to buy them.
