-These are Factory OEM Bolts from a 1993-1998 Jeep Grand Cherokee ZJ 4.0 & V8s. These are 10.9 Grade Made In USA Bolts - Not A Made In China Replacement
- 5/8 Head Size - 7/16-14 Thread - 3.65 Inches Long 10.9 Grade
- Upgraded Bolts For an XJ - Jeep Cherokee XJ's Use a Grade 8 Bolts Which are Rated at 120,000 PSI Strength. The Bolts Off of ZJ's Are a 10.9 Grade Rated at 150,000 PSI. Look in the pictures for just a Slightly Heavier Weight of Basically The Same Bolts
- This in my opinion was for when the used the same steering boxes with much heavier V8 engines they swapped to these higher rated bolts.
