4-Link Cons

So I understand that a 4 link rides better and why but what are the cons to running a 4-link? Why doesn't Ford go with it from the factory, do parts wear out faster or is it just a cost thing?

One con is that you lose some lateral stability. 4-links tend to have more body sway. However that can be corrected with a better sway bar system. So my money would be on the fact that they simply do not want to pay for re-engineering the radius arm system that they have been using successfully for so long. "If it's not broke, don't fix it" mentality.

The steering on your truck was designed around a radius arm suspension. A properly set up lift kit with shocks is going to ride great. Steer great and do everything that it is supposed to do.


Seems like 4 link kits are prone to bump steer. Probably due to guy incorrectly setting up the caster and or someone just not designing a kit properly. Then people buy the dual steering stabilizers or the hydro assist to try to fix the bump steer.

A properly engineered and installed 4 link suffers from non of the above. Mine rides and handles better than the stock radius arm setup did.
