These are the toughest shackles on the market. Don?t be fooled by cheap shackles that will twist and break while your have your Jeep flexed out! Our shackles are made from VERY heavy material .250" (1/4") A50 Plate Steel . Our shackles are are smooth so they don't hang up on rocks (Ours have a completely round end). The shackles are Cad designed, CNC Laser cut, and bent on a CNC Brake (290 Ton). And unlike some of the cheaper shackle lifts that are on the market ours come with GRADE 8 HARDWARE which includes nylon lock nuts. Even if you do not buy our kit NEAVER trust a lower grade bolt on any of your suspension components if you do you are taking a big risk. You can also combine lift springs with a shackle lift to give you the desired total lift. These Shackles will fit 87 -95 Jeep Wrangler YJ. Shackles will be shipped ready to paint.
