Includes the bolts for both the front and rear track bar on all 1997-2006 Wrangler TJ's and LJ's and 1993-1998 Grand Cherokee ZJ's. Includes: metric 10.9 Class (metric equivalent to grade 8) hardened yellow zinc plated flange bolt and flag nut retainer for attaching the front track bar to the axle. Flag nut replaces Mopar part number 6504449. The flag nut is yellow zinc plated for corrosion resistance and is double the thickness of the OEM flag nut so it won't break on you. The prevailing torque flange lock nut is welded to the bracket, not just press fit like the factory ones were. This is a heavy duty replacement that does not require any drilling or modification to use. The bolt is the same size as factory. The rear track bar bolts are (2) metric Class 10.9 yellow zinc plated flange bolts and (2) yellow zinc plated flange prevailing torque lock nuts. High quality direct OEM replacement. This flag nut is our own original design and Region Offroad is the manufacturer. This is sold by a small business in the US and we actually use these parts ourselves.
