Jeep Wrangler JK 07-18 Steering Stabilizer to Axle Bolt with Flag Nut 10.9

(1) 10.9 Class (metric equivalent to Grade 8) hardened yellow zinc plated flange bolt with a heavy duty (twice the thickness of OEM) 10.9 Class hardened yellow zinc plated flag nut.

The prevailing torque flange lock nut is welded to the bracket, not just press fit like the OEM one was, so it won't fail on you.
