Upgrade your junk OEM hub bolts with these 10.9 Class (metric equivalent to Grade 8) hardened yellow zinc plated hex flange bolts. These bolt the front wheel hubs / bearings to the steering knuckles. These fit better than the tapered factory bolts which were designed to reduce cost. They have far better corrosion protection over black oxide and have a larger hex head which is less likely to cause you problems the next time you need to remove them. Includes 6 bolts, enough for both the driver and passenger side. Fits: Wrangler JK and Unlimited JKU 2007-2018, Grand Cherokee WJ 1999-2004. Replacement for Mopar 5012436AB
