Question:

What are the specs for the mounting Bolts supplied? And why only two 2 large bolts shown, any assembly would require at least 4 bolts!

There are 3 different bolt sizes that come with the Blue Ox Signature Series Lift Brackets # BXW4021 for mounting.The ones that you use will depend on the size of your trailer frame. There are 4 bolts for all 3 following sizes:

1/2" x 13 x 1-1/4"
1/2" x 13 x 2-3/4"
1/2" x 13 x 3-1/4"

When I asked my contact at Blue Ox what the size and purpose of the 2 large bolts were he said that they are 3/4" x 10 and they are replacement bolts for the shank and hitch head assemblies.
