View Full Version : California frame?
02-28-2006, 09:11 PM
I have read in a couple of places where guys say they have a California frame. What's the difference, and how is it easily spotted? I assume this is a disireable feature, or does it matter?

Rob, there are two different frame types. One is a 'one' piece and the other is a 'two' piece. The way to tell is the one piece has no seam down the center of the rails top and bottom. The two piece is like two chanels slid together and then welded every 6 to 10 inches. The one piece is smooth along all four sides.
I am ,as others are, of the mind the two piece is a little stronger. However, if you plan to finish the frame for a nice paint finish, the one piece is better looking.
The one piece is commonly called a California frame, but it was used in several other states as well as Canada.
This is a two piece:

Rob also the one piece frame is still welded like a 2 piece frame at the front. Right behind the a-frame-back is where the one piece frame is. Terry.

Great explanation and photos. If I wanted to replace my frame with a new one (too much rust, e.g.) would I try to find a one or two piece frame or aren't there any real options out there?

Mike, I would just get the best frame I could find regardless of one or two piece design. The strength factor is figured in collisions and the way we drive these cars today, that 'shouldn't' be a problem.

Thanks, Mike! I have to start shopping to see if I can even afford one, but now I have one less thing to worry about while looking.

My 56 has a two piece and I'm having to do some serious rebuilding on it due to our use of road salt here in the northeast. After working on heavy trucks for 30 years this frame is not very heavy(thick).

does anyone know how a mid 80s jag rear end can be installed using the stock"cage" without alteration if my spare tire well is eliminated. there is a cage surrounding the differential that is mounted to the original xj jaguar but i need a conversion kit perhaps .........a57kevin

Kevin, it's not a real common swap, so a kit may be hard to find. You will probably have to fabricate what you need. I would check the width and see if you will need to narrow it or anything. That may make it less appealing cost wise. Just a though.
If you go ahead with it, post any questions you may have along with pictures if possible. Thanks

I replaced mine with a one piece and it is really clean. I had it blasted and coated it with epoxy primer and urathane after I skined it over on the bottom to smooth out some jack marks. Those frames were made by Bud Manufacturing in California, thus the name, as supplemental production.
