Does anyone know what the Motion Ratio is for the Front Struts/Coilovers on the DT Model Rams??

A Google/Gemini AI search pulls up 0.75:1 but I can't confirm that anywhere.

Speaking with Dave at Eibach, he says they show 0.62:1 listed in their data for DT Models.

I personally have found that Eibach's Circlips on their Pro-Truck struts are spot-on.

Their Clip#1 (0.0" lift) with a 1" ORP measures exactly 1.0" lift.
Their Clip#2 (0.6" lift) with a 1" ORP measures exactly 1.6" lift.
Their Clip#3 (1.2" lift) with a 1" ORP measures exactly 2.2" lift.

Knowing this, I asked Dave what the spacing is for the circlips on their Pro-Truck struts (so I wouldn't have to crawl under my truck with a caliper to measure on my truck), and he said 11.8mm. Each circlip change is equal to 0.6" lift change.

That calculates out to 77.43:1 as a Motion Ratio by my math, but look at my math and give me your thoughts....
