my 6in lift is stock lenth. no relocation of any thing but my butt off the seat when i hit a bump and no flex. LOL but that is NWOR springs and they look like stacked wiskey barrel rings cut in half. im considering marlin 6's and they require relocating spring mounts for longer springs im betting the flex is way better. im running 39.5's, a 3in body lift and i run slow on corners lol. i also would like to hear from those running 6in marlin's, have you considered 4in lift with 2in shackles? i was thinking about it. im sure if it is a bad idea. we both will know pretty fast. not to steal the topic just interested in the same thing and wanted to bash my nwor crap lol. if i change to marlin befor you deside i let you take my nwor springs for the only resonable price i can think of some where around free or i might give you gas mony to pick them up. there fine on road and rough off road and i cant wait to change them.
