Suspension Articulation and Ramp Travel Index - 2014 Ram 1500 EcoDiesel Long-Term Road Test


I finally drove our 2014 Ram 1500 Crew Cab Ecodiesel 4x4 up our Ramp Travel Index ramp to measure its suspension articulation and determine its RTI score.

If it did, raising it to the highest setting would worsen RTI compared to the default normal height because the springs get stiffer once the air pressure is raised to lift the truck. In fact I just measured a Land Rover LR4 last week, and it had air suspension. In the normal default mode it scored 560 points, but in "high" mode it scored only 457 points. Air suspension set to high mode helps clearance, but it degrades articulation.
