Complete set of brand new front driveshaft bolts for all 2007-current Wrangler JK, JL and Gladiator JT's. All hardware is 10.9 Class (metric equivalent to Grade 8.) Front driveshaft to differential bolts are Dacromet coated. Front driveshaft to transfer case bolts are black zinc plated and the tie brackets are zinc plated. Black zinc plating gives far better corrosion resistance than the black oxide factory bolts. The heads on these bolts have also been upgraded to 12 point to eliminate the stripping problem that the factory JK bolts a notorious for. 12 point heads can take more torque for any given size compared to 6 point hex heads. This is a high quality replacement set that improves on the shortcomings of the factory bolts. Replaces Mopar part numbers 6508553AA, 68003249AB, 5191037AD, 6506497AA and 68400272AA.
