The comments about the OUO parts were very complimentary. Thank you.
I don’t like to have these conflicts on forums I would rather let it be and have my post rest with what I have said. However, you insisting that I posted things that are not true and backing it up with complete bias nonsense has forced me to defend my position.
My post was not to say that OUO radius arms are not nice assemblies. I am sure they work just fine. There are just inherint differences between radius arms and a good 4 link assembly. The prior post was full of incorrect information based on geometrical facts. Not opinions.
But Facts? The good thing about the internet is you don’t have to prove anything and you don’t even need common sense, someone just says it and it is fact.
I am not really sure how you came to those conclusions. Spending a little time on Pirate 4x4 might be a good thing for you doing some research...
If that is where you all get all your suspension design information, that explains your position.
The only thing on a super duty from the factory based on a radius arm setup is the size of the sway bar! The natural binding of the radius arms adds a tremendous amount of resistance just like adding a larger sway bar! Compare a Ram HD sway bar to that of a Super Duty? The Ram HD is a multi link system versus the Super Duty radius arm system!
What does this even mean?? I think your point was agreeing with me but I can’t tell.
A radius arm setup naturally binds up causing bushings to wear way faster than a 4 link setup. A 4 link setup will allow easier movement of the suspension without bind, thus not having as much bushing wear.
On a 2005 + Superduty F250 truck, we are talking about the big rubber bushing on the axle housing. The joints that see low rotational force during cycle on a 3 link and changing it to extreme rotational force thru cycle on a 4 link. On a 3 link they see mainly linear front to back forces and a 4 link adds rotational force using up the deflection the rubber had. You say that is better, I say it is worse.
The bump steer relationship has little to nothing to do with the fact that the suspension uses a 4 link or a radius arm. Bump steer is determined by the track bar and drag link relationship almost exclusively!
If you get your suspension design from magazines and from pirates I can see how you would assume this to be true. For you to say this on public forum has lost all of your credibility on anything you say from here on out in my eyes.
If you are switching to a 4 link versus a radius arm, it is better that you buy a system and not just an upgrade. Many manufacturer's compensate for the great body roll with their spring and dampening rates of the shocks.
This is a good idea, if you going down the road of misinformation you should commit 100%
A well designed 4 link system will not bind the drive shaft much sooner than a radius arm system if the instant centers are proper. However, a 4 link system is a much more robust design than a radius arm system providing you with much more positive axle control. 4 link systems are tunable where as a radius arm system is not! You cannot alter the instant centers of a radius arm system to achieve different effects like you can a 4 link.
This one is great too.
Any one that has a dodge from 94 to 2011 knows how robust that design nightmare is. The design that made the term death wobble famous. Really seems like a huge down grade to me.
So do you sell different frame brackets to achieve different effects? Are the brackets adjustable or just the length of the arms? If you are 100% incorrect on the bump steer should we assume you have this right?
Sounds like you are just throwing out keyword terms like Miss Teen USA South Carolina?
And you can’t see on a 4 link the drive shaft’s pinion angle increases as the axle droops. If it doesn’t, how does it keep the + caster? it has to be one or the other. If I had the choice between having a drive shaft function 100% at full droop and full articulation or having good high speed drive ability at full droop or full articulation I will pick drive shaft function. It is hard to get to freeway speeds with your truck fully drooped or articulated.
We realize you and your online sales team wants to sell your systems and in your hearts you feel that you have the correct solutions to the non-problems you are fixing. You will not see my points because of your bias to your product now or ever. We would hope, for your benefit, we could just agree to disagree.
