Compiled RadFlo Height Adjustments & Results

Adjusting your Radflo's

SOME SUGGESTIONS:

First you'll need to get these: JEGS Performance Products#555-81800 Steel Spanner Wrench Set



Then you'll need to figure a method that works best for you for adjustments. DirtyBacon had a unique solution that works.



You can also adjust the height on the vehicle.

Prepare to spend some time turning your spanner wrench.

HOW TO MEASURE:

Here JamesDowning lists the official measurements to be taken so we have a standard we can all follow. This will allow you to see what others have dialed in and the resulting heights.

I have the hook of the tape measure grabbing on the mounted-top side of the locking collar, when spun all the way up. Using that method, it shouldn't matter if you're measuring yours by running the locking collar up to the top and pulling tape from it, or jamming the tape end into the shoulder at the top of the threads.

Mine I'd read at 3.5".

You report the CV axle center to fender height? That would be another good standard of measure for us to use, since it removes tires from the equation. An average of the left and right readings is also best.

Go ahead and post up a photo or your measurements of your results adjusting the height of your Radflo's. Also post up some details, about whether or not you have bumper/armor.

The upper picture is mine. So I'm at 4 3/8". I thought I had settled but new measurements show that I'm still at the 42 1/4" that I was when I stopped turning. I've put about 1,000 miles on them already. (holiday travel) I still intend to reduce mine. Maybe I will try around 4".

I have 315/70/17 BFG tires. The rear are almost new, the front are fairly worn. All of these things play factors in fender height.

Thanks for posting this Mike.

I updated the first thread to be a little better detailed, hopefully that helps and folks will start posting their measurements.

Talk about spending some time turning the damn things.

I am going to start at 3.75inches myself since I don't have a front bumper and see where that puts me from the center of the CV to the fender, I'll post up those measurements shortly.



And if anyone is curious, this is where mine (and probably everyones) were set to when I got them:

[HARDTRAILZ]

So measure from outside of collar to outside of collar.

Measure hub center to fender lip on both sides and average.

Report on bumpers, skids, or other items on fron thet would add or remove weight from a standard load.


I got some cheap ebay wrenches to try, but really need time to even open my box they came in. Seems to just not be enough hours in the day and going to work and coming home from work in the dark sucks the drive out of a person.

Good info - thanks Erik, Mike and James!

I feel you on that!
Been thinking about adjusting mine higher but work is wearing me out. This a good thread with good info.
Good job guys

Once we get some measurements, we should be able to create a graph to show the general relationship between lift and preload adjustment.

[mikekey]

Alright, I finished mine this afternoon. Got impatient. Still gotta go back and do my ball joints SOON.

When I started my center hub to fender was 25 inches both sides. This is with the BDS 2.5 lift on stock springs with just radiator skid and oil pan skid.

I adjusted my Radflo's to 3.75inches both. And then installed, my resting height from center of hub to fender is now 27 inches. My rake is gone, car is level, approach angle is a lot better than it was.



My CV doesn't look anymore off than it did originally, but there is a change in angle. It's not binding, spins freely.

Passenger Side CV


Drivers Side CV


Hope this is helpful to someone.

Mike, what's the amount of suspension compression with the weight of the vehicle? The biggest thing we want to avoid is too much lift, and therefore bouncing off of the top of the shock all the time.

If you can measure your hub to fender distance with a tire off the ground, that would be awesome.

How do I measure the first one? I measured already with the weight of the vehicle on the tire for my first measurement. And I just remeasured, I didn't have the tape in the center of the hub so I'm actually at 27 from center of wheel to fender on both sides.

[DirtyBacon04]

compare the distance with weight on tire to distance with weight off tire

[mikekey]

Ok, I've measured incorrectly several times today. Guess since I was trying to hold it myself and pushing it back towards the fender. Danee helped me tonight and now I have new measurements. At rest in the drive way: 26 1/2 inches. With full drop is about 27 1/2. Hmmmm....

This might mean that my original height was closer to 24 since I've been an inch off each measurement.

[Trail X]

So you have one inch of downward suspension travel. That's probably just about optimal. I wouldn't want much less than that, or you'll top out on every rise.

[ErikSS]

I checked today, I have about 1 1/4" of downward travel.

[mikekey]

Erik how are you higher in adjustment with more downward travel?

[Trail X]

Doesn't make sense unless the lower shock bushing is shot on his, or something else is limiting your downward articulation Mike.

[Wahugg]

Sway bars? However I don't think they would limit the downward articulation if both wheels were off the ground.

-Wahugg

[mikekey]

Oh good point, I do have my front sway bar connected. All over the road on the Nitto's in the rain without it.

[ErikSS]

I measured from the ground not the center of the hub. I attempted to leave just enough weight on it to account for the tire. Maybe I missed a little. Dunno. I do have some washers in my sway bar. Seems like that could play a factor also.
