Center of Hub/ Fender Measurement

[akarilo]

Yes, you can find all of this info in various threads, but compiling it all into one would be a helpful tool for others when deciding what lift components to go with.

Center of Hub to Fender measurement.

Keep it simple: Facts only.

Mine:

Front: 22.0" (OME 851+20mm packers, ARB non winch)
Rear: 21.5" (OME 862+20mm packers, 4x4labs no swingouts)

Come on people, we can do this.

My Facts:

Front: 22.5" (OME 851+25mm Poly Spacers)
Rear: 23.0" (OME 860, No Spare)

Stock Bumpers, No sliders (factory steps removed), no winch, no spare, removed third seats.

 

[DMOZ]

Sure, I'll play.

Front: 22.25" (OME 850s + 10mm packers)
Rear: 22.75" (OME 860s)

ARB, M12k, Slee sliders, 3rd row removed

 

[Nay]

24" front and rear

F.O.R. Gen II

No flares

Tape measure has to bend around wide Toyo MT's.

So probably 23.5" as the crow flies.

I did this today as well randomly, though mainly to see what lift I would achieve. Hope this helps those with stock setups for the sake of comparison:

Stock 14 year old springs on 100% stock vehicle:
19.5" front
20.0" rear

 

[dafun1]

Ironman 2'' up front: 22.5"
OME 862 rear: 22.25''

Cut stock front bumper, flareless and cut rear bumper with cross member removed. Custom tube bumper will probably drop the rear a little when I get it on.

 

[jfz80]

Front: 23.75'' slee 4'' (reg)
Rear: 24.5'' OME J spring

95 fzj.... FLARELESS at the moment, ARB w/ winch, sliders, IPOR skid and swingout, 2 rows seats
* i would subtract 1/2 inch to get approximate measurement for vehicle w/ flares *

 

[Tools R Us]

24.75" front, J's, 1.5" spacer and ARB POS bumper.
25" rear, J's and 4x4Labs poverty pack bumper.

Rolled across the scales at 5640lb yesterday, with about 300lb of tools aboard, so close to stock weight.

 

[Shipwreck]

4 year old Slee 6" lift

Front: 24.5"
Rear: 25.25"

With flares, ARB + M12K front, stock rear bumper .

 

[bhmmapping]

Front: 22.5" (OME 850, ARB non-winch)
Rear: 23.75 (OME 860, removed third row, trailer hitch, all rear bumper pieces and spare tire)

flareless with custom sliders that probably weigh about 70 lbs.

 

[malottki]

Front - 22.5 (ironman 2in)
Rear - 23 (ome 860)

stock, minus the side steps and third row seats.

Do we dare bring up caster correction.

This is a great thread, but possibly mentioning CC correction might be relevant. If one where to look at this thread, there could be so areas that need attention.

Per Say: My original post on measurement sure was what it is, but I also need to correct my CC now. I stand currently @ -1.2*.

Disregard if this is the wrong place to bring that up.

Wouldn't hurt to include it I guess; "Knowledge Is Power", or somthing like that.

25" rear, J's and 4x4Labs poverty pack bumper.

A stock weight of a cruiser is 4750. You call that close to 5640? Just sayin'.

My measurements:

Ft: 25.25" (Slee 4" med.+ 1" Slee spacer)
Rr: 26.0" (Slee 4" med. + 1" Slee spacer)

The rig got scaled at 5700 lbs with tools and recovery gear.

The published curb weight differs depending on year, model, etc, mine is a LX, IIRC it's just short of 5000lb and most were delivered heavier than published due to added options, undercoat, etc.

The scale is at the security booth entrance of one of my customers, as I'm signing in, often look at the reading. Was there to deliver tools, had ~300lb of tools that were delivered, so 5640-300=5340.

My rig has 37" tires and wheel spacers, so what ~50lb a piece more than stock? The tires are on the scale, but not suspended, so don't effect spring height. 5340-200=5140, in my book that's pretty close to published curb weight.

It's significant because without an estimated suspended weight, hub-flare measurements are good trivia but pretty much worthless. For example; IIRC cruiserdan runs J's and a 1" spacer in the front, when our rigs are parked close they look very different. IIRC his measurement is ~2" shorter than mine due to the added suspended weight he carries.

And the height of my F.O.R. Gen II reflects my tube bumpers and otherwise general lack of additional sprung weight.

Correct. J's up front with some Mickey Mouse spacers and 864s in the back

Actually Kevin made the spacers for me and they are a real work of art.

I am about 2 inches shorther than Kevin's truck and mine weighs 6,320 lbs.

600 lbs extra compresses the suspension 2" meaning your springs have a rate of 75 lb/in

 

[GrindCruiser]

25,25" Front (2" custom steel spacers)
26" Back
OME coils (unknown specs) front custom bumper + 12k

The OME rates are documented. From the numbers and what I know of both rigs, my guess would be a little over half a ton difference in sprung weight. We don't have individual tire weights, will guess at ~250lb per tire.

The ~2" (~ = about) thing came from memory of a phone conversation (has been awhile, feel free to look up Dan's spacer making thread if you need to document the date). I'm old so memory isn't the best, but Dan's was 23 inches and change (don't remember the change), mine is almost 25", turns out to be 24.75. So on those assumptions the difference is about 1.75".

Dan runs 1" spacers, I run 1.5", so the spring difference is ~1.25". 1.25" and 250 lb is pretty close to the OME spec. Spring rate isn't an exact indicator of load response, a lot of other things come into play, bushings have spring rate, etc. But will give a good idea of what changes to expect when changing springs on the same rig and the "rules of thumb"/measurements from like rigs can give some idea what to expect when setting up a new rig.
