I know it’s been a little while since asking about lifting my ‘11 Pro 4X, but I’m going to order it this week. I’m thinking about going with Nisstec Complete OME kit with Dakar leaf packs. Question: one kit is $1596 with shackles, the other $1510 w/o the shackles, how important are the shackles? Don’t mind the extra $100, just don’t want to find out after the fact they are needed. Opinions on this company & this kit please. Thanks
