Stay away. Had them put a budget boost on my New Jeep Wrangler, day after i started having \""death wobble\"". Darwin coaxed me into buying a new steering stabilizer to \""fix\"" the problem. SS only masks the wobble from the driver until it's severe. Went back in to purchase a new HD trac-bar, again Darwin told me that's not the issue and up-sold me Into an AEV lift because he \""guaranteed\"" it would fix the death wobble. Within two days I was still having wobbles. I finally went in and bought the Trac-bar I originally had intended to get before Darwin led me $2500 down a rabbit hole. Sure enough trac-bar significantly reduced the frequency of my wobbles, but hasn't fully eliminated them. Darwin and his staff have been nothing but condescending when I've come in with my issues. I wouldn't spend another dime with these guys.
