Manufacturing 4130 Clevis Mounts

Today we spent a little time manufacturing some trick clevis mounts for the Rock Bug’s PSC double ended steering ram.  These clevis mounts are almost identical to the mild steel ones we currently sell on our website (part #: CLV-001).  Biggest difference here is, like everything else on the buggy, they are manufactured from 4130 chromoly steel.  The connecting link between the ram and steering arm will consist of one chromoly clevis mount, one chromoly threaded insert, and a small piece of 1.25” x 0.095” wall 4130 tube.  After the connecting links are all tig welded, they will be heat treated to carry a final yield strength just over 170,000 psi.
