Question:
Hi - Im rebuilding a sled trailer into a utility trailer and it has hubs threaded for 1/2 x 13 lug bolts left thread on the left side. I want to convert to standard 1/2 x 20 right threaded studs on both sides just for ease of maintaining. The hubs themselves are in good condition and turn smoothly, so I figured I would press in new studs. Can you suggest an appropriate stud and do you think I could install myself? Thanks!

Hey Jim, thanks for reaching out. The left hand thread style lugs are basically obsolete so converting to the 1/2" - 20 right hand thread style lugs will be the way to go. You will want to take a closed look at the size of the current studs to make sure you get the right thing.
For example, the Kodiak Wheel Bolt # K12WB169 is 1-11/16" long and has a 5.45" knurl diameter. You will want to check and make sure this is appropriate for your hub. If you need a different size just let me know and I am happy to look into it. Or you can use the link below to see our full selection of 1/2" wheel studs.
This is not too hard to do by yourself if you have the right tool and a little know-how. A press would make things a lot easier, but if you can hammer the old studs out you should be able to hammer the new ones in. Use a wood block and a hammer or mallet to get them started. Then you should be able to thread on the nut and crank that down until the studs are seated all the way.
