Thread: MII cross member advice on my frame

Tweet

Speedway, Heidts, and a number of other companies make some very nice crossmembers, they are made from either 10ga, 1/4" or 3/16" steel plate, not sheet metal.... The main part of the crossmember starts life as a piece of 10ga. wall 1 1/2" X3" or 4" rectangular tubing cut and trimmed to fit for some of the crossmembers, the rest start as steel plate and bent to the correct configuration. They are also jig welded, either MIG or TIG depending on your preference and your checkbook! The hats are also 10ga. steel or larger, and stamped out with a huge press. I've used many of them and have never had a problem. My experience with Fatman stuff was never very good....guess it depends on who you talk to. Personally, I prefer the weld in units and I always add a gusset or two as well as boxing the frame rails from the front to at least the transmission crossmember with 10 ga. steel. Any units I've ever seen that crack or fail have always ended up being installer error.....
