It's also a *VERY* hard bolt.
The front suspension on my Jeep Cherokee is very similar, albeit on a smaller scale. Torque spec on the factory bolt is 75 ft. /lbs. , it's also got an odd profile to it. The hardest bolts I could get aftermarket all snapped at the thread root at around 50 ft. /lbs.
I put a 3rd Gen kit on my 99 (SolidSteel, through Rip @ SourceAutomotive,) and the bolt I removed shared the same characteristics as my Jeep.
In short, I'd go back to Dodge for this bolt.
