(8) Metric Class 10.9 (metric equivalent to Grade 8) hardened yellow zinc plated flange bolts and flange prevailing torque lock nuts for the front or rear upper and lower control arms compatible with Jeep Wrangler TJ's and LJ's 1997-2006. These are the correct factory size metric bolts. Includes: 4 Upper control arm bolts and nuts and 4 Lower control arm bolts and nuts. This is for either the front or the rear, if you need both order 2 sets. High quality direct OEM replacement. NOTE: If you have an early TJ (mid-1999 or earlier) that came from the factory with cam bolts for the front lower control arms to the axles you will not use 2 of the bolts in this kit and will need to either reuse your cam bolts in those positions or use a cam bolt eliminator kit. I have a cam bolt eliminator kit available in my store separately. Click "Region Offroad" above where is says "Sold by" to find it. Later model TJ's (mid 1999 or later) will use all the bolts in this kit and will not need cam bolts or an eliminator kit. Note: some later than 1999 TJ's may have cam bolts on them since they came from the factory with knock out plates to give the option of using them. Check yours to see what you have. The rear control arms did not have cam bolts and will use all of the bolts in this kit on all TJ's.
