Stiffening factory '67 C10 frame rails

I have the Porterbuilt in my 72, great upgrade. Personally I don’t think the Summit unit looks anywhere as strong.

Do any of them allow you to push the rear wheels back? I know the normal pb crossmember allows you to position it more rearward, if you are not running adjustable length trailing arms then I would want to know that. Other than that I am following along as I’d like to hear opinions as well. These frames have a ton on flex.

Not that I know of. My cpp tubular trailing arms are fixed length as well.

what is wrong with welding on the rails? I just had my 64 a-body frame boxed in with an HPI kit and I cant imagine the rails of a a-body being much different than frame rails from a truck. The summit kit is just a rebranded HPI kit.

It'd probably be fine, but something about GM not heat treating/stress relieving the truck frames until the mid 80s, and that's why everything is riveted together??

Awesome, good to hear someone who actually owns one of them.

Did you do any additional sort of bracing anywhere else? Did it seem like it helped a lot?

No other bracing. I have ridetech streetgrip installed, with AGR steering box. Truck drives awesome.

the first time I drove out driveway and through gutter, the lack of twist was immediately noticeable. The truck feels very tied together and allows suspension to really work.

Prefect thanks Roger.
I plan to order a Borgesen 12.7:1 box as well. Are you running a steering cooler by chance?

No steering cooler, I don't drive it that hard

Does it remove all 3 of the original crossmembers? Transmission, parking brake and trailing arm mount.
