Thanks for reaching out Mike, happy to help!

For the Reese Pro Series 49903 weight distribution hitch, the head to shank mounting hardware is listed in the installation manual as:

(2) 3/4"-10 x 4-1/2" bolts
(2) 3/4"-10 nuts
(2) 3/4" conical washers

Unfortunately, Reese does not offer those bolts as a separate replacement kit anymore. If your existing hardware is damaged or missing, you can replace it with Grade 5 or Grade 8 3/4"-10 x 4-1/2" hex bolts, along with matching 3/4"-10 nuts and conical washers. When installed, the manual specifies tightening the bolts to 260 ft lbs of torque.

What model of trailer do you use with the Reese Pro Series?
