CPP Trailing Arm Conversion

[JW76]

I posted some pictures of my 86 longbed trailing arm conversion in my build thread. They are just process pictures. It is currently disassembled for final welding.

As a bit of trivia CPP's '73-87 trailing-arm kit was prototyped on my '79 Big 10 right before I left for Americruise with it. It is the only one CPP built that doesn't use a notch in the frame. When they went into production the notch adds 1 more inch to upward travel before it hits a steel bed floor. I don't know what happens to wood-floored stepsides.

As far as the tubular trailing-arms go, I know of one failure, and it was a diesel powered C10 built for competition pulls. When CPP heard about the failure Danny Nix, CPP's engineer asked me to bring my truck by the shop to put it up on a lift and see what 12,000 miles of my abuse had done. Just for the heck of it we took the '79 out on the back streets of Fullerton, and did some real nasty block-long burnouts, and still nothing.

As I remember the wall thickness was doubled on CPP's tubular arms shortly afterwards. We never did an install tech at CCT on the '73-87 T-arm kits, but there are plans to do one on my '75 Big 10 with a 454 in it.
