sumo springs vs anti sway bars

Recommended Posts


Welcome to the FMCA Forum.

They both reduce swaying, but in very different ways.

The Sumo springs add to the effective spring rate, so less sway, but, also affect ride quality.  If underloaded (actual weight under GAWR's) this could give you a stiffer ride.  If close to or overloaded, it will help with ride quality as you will not bottom out as easily.


Sway bars and stiffer sway bar bushings abosolutely help with sway with no change in ride quality/stiffness.


So, first question is what are your actual axle weights Vs GAWR's?
