Hey Peter,

Although thread lock is not necessary to install the hitch, # e98838, it is always recommended. Its especially recommended on applications where the bolts are exposed to repeated vibrations/road impacts like a trailer hitch. All it is going to do is really secure those bolts in and keep them from coming loose after frequent towing.

I recommend # LT37420, Loctite, we use it on all of our hitch installations at our facility. Are you looking to tow with your hitch or use something like a bike rack more often?

Thanks Nick, The hitch is only being used to carry a Thule bike rack. It won't be used too often. Pete Sposato

@Peter If you would rather not, there is not a downside to not using it. Hitches get torqued down to a specific measurement for your vehicle so the hitch will still be installed securely, it is really up to you. The thread lock is just added security. With a bike rack not used too often you won't have any issues or concerns installing without it.
