Getting ready to order my OME 2.5 lift, had a question

[whosthecoolguy]

I run the 2.5" lift on 33x10.5R15 with heavies in the front and a 10mm rim packer and meds in the rear. I also have an ARB and an 8274.
It runs a little stink bug but looks good in my opinion, handles really good to for a big daily driver.

Pics? Been thinking of about the same setup for my 91

So what all do you have to do to recalibrate the speedo and change the shift points? Is changing the shift points as easy as adjusting the shift cable or does it have to be done through the ECU?

It depends what size tires you're going to run. I know Slee sells a speedo gear made for 33's. They also sell a speedo correction box to calibrate for any tire size/diff gear ratio.

I'm going to calibrate the speedometer w/ the Scangauge 2 and keep the power button on to help w/ the shift points. Just have to remind my wife that her stock speedo will no longer read correctly and to use the Scangauge instead.

So I'm getting ready to order my 2.5 and was talking with a local shop earlier. They said to go with the heavy springs in the front and the mediums in the rear. They said that the mediums in the front sag over time and get sloppy. Who agrees/disagrees with that?

I just wanted to be sure before I ordered them.

Also, who has the best prices and is most reputable?

thanks!

Before you order just want to make sure you have considered other lifts since you are pretty new to the boards (1 week).

I personally plan to go with Friankies 3.5" lift. If that ever happens we shall see, c'mon economy and job stability!
Sorry kind of went off on a tangent....

I have the OME heavy springs in the front and the mediums in the back. This is often called the level stance.

Just remember that a lift can cause vibration issues when you drive especially when you go 3" and higher as with the level stance springs.

You will have to adjust the LSPV or the LSSA to balance your brakes after the lift.

You will have to correct caster with the yellow bushings or maybe even use Slee's blue bushings.

You might even have to get adjustable panhards, so you are not off center and leaning to the driver's side.

If you go with the level stance springs (850/860), it's probably good to have some weight in the front (bumper + winch) and some weight in the back (rear bumper).

If you don't add weight at all, then you might be riding a little stiff and high. In this case with no added weight, the 33 tires will look smallish. If you go to bigger tires, then you need a greater speedo correction and you will be real sluggish going up hills. So, bigger tires might lead you to re-gearing to 4.56s.





So,

 

[S.CarolinaFZJ80]

Bluetribal is right. Go for the Frankies Off Road 3.5"

You'll be much happier. I can attest that the OME lift is harsh.

I went with the Marks conversion box from Slee...it is plug and play between with the factory wiring loom and speed sensor on the trans, and I had calibrated quite quickly. Running 315's and 4.88's and it is dead-on accurate as confirmed by my GPS. This also allows you to have two sets of tires, and a simple flip of a switch will change the correction.

Slee - Speedometer Correction

Another option would be to have a local shop build a conversion box, but most hack into your harness.

I used a Yellowbox to correct my speedometer/odometer/shift points. Less expensive than Mark's box, but it does require some wire cutting and splicing.

I bought the truck with an OME medium lift (851/860) and 285/75r16 BFG ATs already installed (thanks Louis!). Between then and now I've added an IPOR skid plate, Metaltech sliders, blue caster bushings and removed the 3rd row. The lift is still slightly rear high. It flattens out nicely when loaded up with a stuff/people, and it also rides a whole lot nicer when loaded. With the truck empty, driving to work can be quite bone-jarring, especially on square-edged bumps. I'm interested in the possibility of a FOR 2.5" lift, as the ride is supposed to be much more supple and forgiving.

If I was starting with a stock truck today I'd probably go with a FOR 2.5" lift, 35" tires and the Yellowbox speedo correction. I'd wait until the lift was installed to check the caster and order a solution accordingly.

Ugh, I think all you guys have successfully talked me out of putting the 2.5 OME lift on the truck. I want this truck to comfortable to drive long distances and such. I don't want any kind of bone-jarring ride, or messed up transmission shift points and speedo, or crazy vibrations. I think I'm just going to put 33's on it and roll.

I am open to other lifts that are more comfortable, but don't want to go as high as 3.5. Just a 2 or 2.5 is what I am after.

Dang I was all exited about a lift! I want to be able to drive this truck comfortably though.

Maybe the non-lift OME setup???

I wouldnt shoot down the lift yet. I will admit that having heavy all the way around it is a somewhat rough ride, downtown Atlanta doesnt exactly have the best roads. For sure get the tires cause I think the truck looks a little weak without it.

If you get the 3in OME lift that will give you about 2-2.5in of lift depending on heavy/medium. Keep looking into it.

 

[Hayes]

Yeah man. Don't jump to conclusions.
I think you should do a little more research.

Don't quench the excitement just yet. I started with the stock height OME lift (1" lift) and the ride was vastly improved over stock. No more swaying in the corners...felt nice and stable. However, for me the 1" lift wth 285's got old in a hurry, which is why I would go directly to the 2.5" lift. I can almost guarantee you will want more lift if you go with the OME stock height springs.

I am running OME 850/860's (Heavy Front/Medium Rear) on my 285's and love it. It gives a nice level stance and its definitely not a harsh ride by any stretch, it just feels more firmly planted especially when cornering. This setup is very comfortable for me and the family and we drive across the state frequently in the winter time. You just need to add some of Slee's blue bushings for castor correction.

As far as tire size 285's work best for how we use our rig. We don't wheel very often, primarily drive over mountian passes in the winter time and I wanted a size that wouldn't slow me down too much over steep grades. I can hold 70mph with the 285's with a fully loaded rig. Slee does make a speedo correction gear that corrects for 285's which is also nice.

Good luck!

 

[informationjunky]

850J's, fronts 863 rears, 315 BFG KM2's with stock gearing.....downside is I hit the "hight bar" at the ticket booth at Hartsfield, but clear everywhere inside.

IMHO 35's for J's, 285's for 2.5 lift.

 

[Turbo D]

yeah, maybe i'm throwing in the towel too early. What are your thoughts about mediums/mediums? I am not overly concerned about the rig being level. Would mediums in the front give a more comfortable ride? Maybe less caster correction and such with a slightly lower lift?

 

[VCCruzr]

Just do it! My 850/860 rides very comfy. It was a huge improvement over stock, which rolled and bounced and was way too soft. You wont be disappointed with the ride, plus it looks damn good!

I'm going to install the 2.5 mediums setup on my truck soon. 851's in front, 860's in the rear with 2* castor bushings up front. I have 285's on right now with Slees speedo gear and its great. I just want a bit of a lift so I can build my bumpers this winter. Once I finish the bumpers, I'll see what (or if) springs i need to switch to.

If I install them before you order yours, i'll take before/after pics for yah.

Good deal

Let me ask you, what made you decide on running the mediums up front instead of the heavys? More comfortable ride, less issues?

^^^What he said... You will have stinkbug with mediums all around and if you ever install a winch or aftermarket bumper (ARB) you will definitely want the heavies in front. Remember the only difference between 850's and 851's (Front - Heavies / Mediums) is only .8 inches IIRC. The spring rates are exactly the same.

The ride is vastly improved with the 850's/860's it is not harsh at all. You will love it. Trust me...

I talked to Christo today about what I wanted to use my truck for, and he recommended the mediums for my application. I didn't want to go with the heavies all around because I dont have my bumpers built yet. Once I finish my bumpers, i'll decide if I need new springs or not, but while i'm building them (and other parts) the mediums should work fine.


I'm wondering what all the guys running heavy front/ meduim rear do when they load up the truck with lots of gear in the back? You have a level stance on the street, but then when you go to use the vehicle for what its intended for, the back end sags under the weight? Doesnt seem very logical to me, but I'm new to LC's being a Rover guy all my life...

read over the FAQ page also. There's lots of advice on here that seems to conflict with the FAQ thread on OME lifts, so newbs like us are more easily confused!
