A few things. I didnt like the ride quality of the spacer lift or how the Jeep had body roll around corners. For some reason I was constantly replacing front struts that would go bad after less than 6 months of being installed. Didnt get as much lift out of the spacer lift compared to the Old Man Emu lift. The rear end squated with any kind of weight which was fixed with the OME HD springs. It also stopped the body roll around corners since the coils have a higher spring rate. Most members who are currently running the OME lift had a spacer lift prior.
