My brother and I went to the OHV park near Mapleton KS this Saturday to test out some suspension upgrades. The 14 has the front sway removed, the 12 is non KDSS but still has the sway. I think without I get a little more compression. Both ride fantastic on the trail. We played on the RTI ramp, could have maybe gone a hair higher, but didn't push it. These trucks did great.
