Compiled RadFlo Height Adjustments & Results

[OregTrailBlazin]

The measurements are going to vary a bit between different rigs. Eibach has a 3MM+/- quality standard. Meaning you can have as much as 6mm difference in free height between any two coils. That paired with weight differences and chassis loading we've seen allot of different exposed thread measurements. I've had a rig that had as much as 1" difference right to left to get it to sit level. That particular case could have had many factors including the weight of the driver to make that happen... But point being, don't be disappointed or discouraged if your numbers are coming out different from others.

Once we get some more measurements, we can hone this chart in to be more accurate, but based on the measurements so far (Mine, Eric's, and Mike's), the following chart seems to be accurate.

Anyone else who has put their radflos on, please update this thread with a good measurement of your spring adjustment, and the measurement from your hub center to your fender's bottom lip.

James do you care about how they come from radflo?

[Trail X]

Sure, that's a worthwhile point on the chart.

MikeKey also took before measurement of the screw threads, from picture I see about 1 1/4". I got 1 3/8". Could call this stock. Hub to fender on driver side 21", passenger side 20 15/16". I have no armor, no steel bumper, no body lift. Hmm my numbers don't seem to fit the chart.

[Trail X]

I got 1 3/4" as shipped, that's what Mike's picture says too. That would be a lot closer to 21in. Did you take a picture of your measurement? I'm wondering if you didn't measure it per the datums set earlier in this thread.

Updated with Yoda's as-shipped numbers.

Sorry read all the "standards" but typed in what I measured when I got them, which was not per the datum. I got the same 1 3/4".Gotta love the road salt NY uses. LOL

Got around to installing mine today.

NOTE: I have an LT which has an additional plastic shroud around the fender wells, so this may skew the measurements slightly. I just took a measurement of the plastic and it is about .25", and while the shroud is tight on the fender well, there is no guarantee that there are no gaps between the shroud and the fender well.

Weight:
No body lift, stock bumper, MDB rad skid, MDB oil pan skid

Before:
'83 springs, Bilstein Shocks, Liftmeister 3" spacer

After:
Radflo at 3.25" (see picture below). The picture shows just shy of 3.25", but when I tightened the locking ring on, I took it to 3.25".

All measurements are made with the tire mounted. I measured from the hub center to the fender. For the with weight measurements, both front tires are on the ground. For the without weight measurements, both front tires are off the ground. This should take the swaybar being connected out of the equation. The measurements between driver and passenger sides were surprisingly the same.
Measurements:
Before with weight: 21.5"
Before without weight: 23.5"
After with weight: 22.75"
After without weight: 23.5"

[HARDTRAILZ]

88 w marks 3. 25.25 center to fender
Radflo at 3.5. 26.25 center to fender
Full extention I found to be about 27.25.

This is with 3 inch body lift, full compliment of skids, bumper, and winch.

[mikekey]

I adjusted mine to 3.50" new measurements coming.

[Trail X]

I'll post an updated chart when you do.

So far, Kyle's numbers are exactly the same as Eric's, and Mike Firefox's are right inline too. MikeKey, yours look higher than the trendline from what I can see.

Im adjusted 3.25

Matt, that helps me zero without your hub center to fender height... but at the same time, you've got an envoy, which fenders may skew the whole thing. Do you know the difference in fender height between an envoy and a TB?

I will tell you when I get home. Not stock but I will give you my measurement.

Finally got mine installed.

No body lift, stock bumper, MDB oil pan and rad skids

Before: stock suspension 19.0"
Radflo set at 2.25

Right 21.5"
Left 22.0"

Set Radflo to 2.0" on the left for 21.5" on both sides.
Left side UCA squeaking maybe the cause.

Doug,

More likely, it's that the concrete you were parking on wasn't completely level, or you had more stuff loaded on one side than the other, or a completely empty or full tank of gas, etc.. I have, however, seen a TB (that as far as anybody knows, had never been wrecked) that had to be aligned really different from side to side to get the camber right, which did make one side sit higher than the other. Regardless of which one it is, I'd personally want to test it parked in the same spot, but the other direction, and in several different spots that I was pretty sure were all level, before I put more preload on one side than the other.

[mikekey]

I have two collapsed body mounts which have created a slight and noticeable tilt to one side on my rig, however I have a body lift with might be exasperating the effects of the collapsed mounts.

[bartonmd]

Shock measurement of 2-7/16"
Average fender to hub of 21-7/16"

This is with my bumper and skids, and with my tire/fuel/jack carrier loaded on the back.

ETA: This is probably why my suspension feels so good compared to some of yours, why I get very little topping-out, even offroad, and why my stock CV shafts haven't been touched and don't leak yet. I'm more toward the middle of the suspension than a lot of you. I'm trading off ground clearance for suspension movement. I know I'm about right on the static sag (should be ~40% of suspension travel, from what I gather, for trucks. More specifically, 30% for a street and high speed rig, to 50% for an all-purpose trail rig), because they start to top out and bottom out at about the same speed. Having said that, since we are height limited by our suspension setup, everybody has to make the call -- for them -- about what trade-offs they want. Height vs. proper sag.

I'm hoping this is a good place for this question. I installed my new radflos !! But I noticed something when comparing to the MarkMC 3" Lift with the KYB shocks. Looking at the pictures below, it seems as though my previous setup was between 1/2" to 1" longer than the radflos. This means I had more down travel (droop) available with the MarkMC setup vs the radflos. I had no CV binding with the MarkMC setup at full droop, so I was curious if I could put a spacer (above the radflo assembly) to give me more down travel and just back off on the collar spacing (which is pretty cranked up anyway with all the weight in the front).

Thoughts?? Anyone tried this?
