Complete rear leaf spring and shackle bolt kit for 1984-2001 Cherokee XJ and 1986-1992 Comanche MJ. (6) Metric Class 10.9 (metric equivalent to Grade 8) hardened yellow zinc plated hex bolts, (6) washers and (2) flange lock nuts. All the hardware is 10.9, even the washers. These are an upgrade to the poor fitting factory bolts that only had a small shoulder resulting in a loose fit. They are fully shouldered for a perfect fit. The yellow zinc plating also has far better corrosion resistance over the black oxide factory bolts. These are a high quality direct OEM replacement that require no drilling or modifications. Works with factory or aftermarket leaf springs and shackles. Works with the factory welded nuts.
