Description
Here at Forged Offroad we have seen many lower A arms that have been damaged by the OE lower shock bolt not being properly “shanked” as you can see this slight damage on an A arm that has less than 10,000 miles on it.
In the off road world, every bolt we install has to be a minimum of a grade 8 (or 10.9 metric) and has to be properly “Shanked”. Shanking is simply a bolt that the shank (unthreaded) portion of the bolt spans the entire distance of the opening including the tabs. When threads are cut in or rolled into the bolt, not only does it reduce the diameter of the bolt, it also adds a weak spot where the bolt can break.
We have seen some lower A arms that the threads have made the rear hole oval, and even the 406 foot pounds of torque called for by Ford will not make that bolt stay where it is. This is one reason we have found for the front end “clunk” so many Raptor owners find them selves experiencing.
As you can see from the picture, our bolt has a longer shank than the OE bolt.
