exactly what the hell would a 4" mj pack do to a stock xj, would it match up eye to eye, and wouldn't that be like 7" of lift or some crap? just bored as hell and starte thinking of ways to make a jeep FUBAR as hell
No. As stated they are longer, they are also a different shape. Among other issues you would have extreme difficulty getting those to fit. Go grab some chero springs.
