YETI XD™ 9/16TH TRACK BAR BOLT UPGRADE KIT CONTAINS GRADE 8 MAGNICOATED HARDWARE TO REPLACE YOUR FACTORY JK, JL, OR JT TRACK BAR BOLTS. THE STANDARD/OEM BOLT IS AN M14 BOLT THAT IS SLIGHTLY UNDERSIZED FOR THE BUSHING/MOUNTING HOLES ON THE VEHICLE. THIS BOLT KIT WILL FIT SNUGLY INSIDE BOTH THE BUSHING AND THE MOUNTING HOLES AND CAN HELP ELIMINATE EXCESS MOVEMENT IF TORQUE FALLS OFF.
*NOTE* For the front track bar be sure to install the frame side bolt so that the bolt head of the bolt is on the backside of the bracket (closest to the axle) and the nut is on the front side (closest to the front bumper) as this will ensure proper clearance from the axle at full compression
