A buddy of mine is offering to sell me 4 2'' shackel lifts off his YJ for $50. He says he only used them for a year, and they still work great. Would this be a good option for me as I am looking for a lift so that I can add largers tires to my YJ. Was hoping to put something in the 31' range for tires for it. Not real fimiliar with shackel lifts, or lift options in general. Still a newbe with my wrangler. Any advice you can dish out would be great.
