That’s a fun trail fix.
The thread diameter connecting the inner to the outer must be larger for hoss 3.0 than hoss 2.0. That’s why they are not interchangeable. Is that true?
If so they would be slightly stronger. Does someone know the diameters for hoss 2.0 and 3.0 inner threads...
I used two spring compressors without removing shocks on the rear for 6100s. The rear springs I have are about 200 lbs/in and I was going from 2nd lowest setting to lowest setting to drop CG some. So not needing to compress springs very much. Not sure I would recommend this if you are going up...
@telenerd Curious what the measurement is at full droop? Did you get that when adjusting links? Do you have a ford spec number for max CV angle of drive shaft?
I really appreciate the detail of your write up and investigation of proper link lengths.
Interesting thread.
6100s have very similar extended lengths to oem coilovers. So they will not produce significant angular geometry differences than oem. Both in front (CV axles) or rear (drive shaft CV).
If Maintaining oem coilover mounting hard points, It is the coilover extended length...
Some math for the nerds.
Basic trigonometry defines the lateral wheel motion assuming perfectly rigid bushings. Plot shows the OEM configuration with a perfectly level Panhard, and a 3” lift to OEM without leveling Panhard. Panhard length is 44”.
Notice a level Panhard provides a symmetric...
With a solid axle 5 link Panhard setup, the lateral motion of the axle (and hence wheels) is constrained by the Panhard arc motion. No travel is gained by panhard/axle relocation bracket, just a more neutral arc motion of Panhard that will provide less axle lateral motion near full rebound.
Cost is based on demand not quality. Sometimes they are aligned, sometimes they are not. You get what you pay for is silly. People were buying broncbuster tierod braces (with a square cross section 🤣) for >$300.
I am sure these are high quality and no disrespect intended towards the...
Yeah the front/rear balance is kinda off with 400/250 combo. 400/200 should be much better. The 500/200 combo seems ideal and it is pretty easy to adjust preload and get ride height near shock mid stroke. Also keep cg down a bit. Not ideal for 37s tho. Great for 35s.
It seems that you are...
Eibach 3”x16” 400 lbs/in spring has 9.4” of available travel. Shocks have 5.5” stroke. Assuming 0.5” of hard bump stop at jounce end then conservatively, 9.4 - 5 =4.4 inches of preload max. Call it 4” to be safe. Carrying 1500 lbs on corner in front (stockish) that is 1500*1.6=2,400 lbs to...
Good read. I for one appreciate this detailed post and the time it takes to write this. I don’t even bother with threads that just have video. Don’t even open them. Thanks for your thoughts.

EDIT. Correction to be more concise.
Under static loads.
As far as the ball joints are concerned, their reaction forces are dictated by the scrub radius moment arm and they don’t care where the wheel bearing is located. Wheel/knuckle acts as a rigid body.
As far as the wheel...
Of course. My comments were not about your post but more general.
Your analysis of the bearing moments is accurate just not complete. The applied moments are the force (normal force acting on tire contact patch centroid) times a moment arm. The full moment arm distance needs to include the...
I doubt this. Wheel offset and scrub radius dictate the bending moments applied to the wheel bearings so that is really the main point.
Curious if @Ducati1098 has seen many wheel bearing failures on stock wheels.
Lots of strange and conflicting information in this thread. 9” wide wheels have a center line at 4.5” from edge. So 5” backspacing has a positive 12.7 mm offset (1/2”). That is not super aggressive. Not even negative. The pic does seem to show a negative offset but hard to tell. No idea where...
