I made a small lift using a 2015 Jeep Wrangler Unlimited 2.5" American Expedition lift. I rode uphill a bit because I was worried about performing well on the freeway. After raising the AEV, I experienced some hesitation and judder at highway speeds. After installing the Rancho Geo Correction Brackets, wobble and judder are completely eliminated. I am satisfied with this product and difficult to be satisfied.
