For all the bolts that attach to the frame in addition to torquing the bolts down should I be using thread lock?

 

They also make a 13 piece kit which includes all the replacement nuts and bolts. I have ordered kits from ebay twice with no problems. I have run my current kit for about a year and a half and the only reason I had to replace a few parts was because of the accident. Here is a link to the person I bought from, and they are good people to deal with.

There are other kits but I can only vouch for these as I have personally used them twice with no problems. The kits they offer are HD = Heavy Duty and are the most current versions as they have been updated through the years.

Hope this helps
