Well my search is over. I found myself some TC UCA used. The seller was in the process of doing a FULL titan swap: suspension, V8, Tranny, diff and rear axle. HE was missing the original mounting bolt and found some in his shop that he included. Attached are some pictures. The bolt looks to be a grade 9 bolt. This suggest that it is not the original as the OG was only grade 8. I am also not sure if it is long enough. Since the OG was grade 8 that would mean it is a SAE bolt and not metric. If I needed a new bolt cause this one is too short, what size?? Anyone have input on the topic (regarding this specifically or general info on the topic all welcomed).

I assume you are talking about the spindle bolts. Anything at or above a grade 8 (or metric 10.9) should be fine as long as it is the proper diameter and length. It should also only be partially threaded as to not gouge the ID of the misalignment spacers. Standard vs metric doesn't really matter for this application, although it may be annoying to need a standard socket when the rest of the truck is metric.

Yes the spindle bolt. It is smooth for the section within the spacers. But the threads stick out just past there in the knuckle section.

THe question is what is the diameter.

The TC UCA uses a 1" uniball vs the 3/4" (?) ball that PRG uses (or use to, can't find spec anymore). 1" is what they use for the titan arm.

I contacted TC and got 9/16"-18 x 5" grade 8. Looks like I should be ok. Mine are 9/16" x 5" not sure the thread size.

TC also pointed out the link to the installation instructions. The bolt size what in the instruction.

TC got back to my question in a couple of minutes. Helped me out like I was a REAL customer, even though I told them I bought the part 2nd hand. Did not even point out the fact that the bolt spec was in their instructions, which like an idiot I missed.

This has been my only dealing with TC. But from this experience it will not be my last. Good service, wish they made more products.

I totally agree on TC. Customer service is tops, even on kits they don't make anymore they still carry many of the parts needed if you buy second hand.
