price to chrome steering parts
crider:
I love that reply Bruce!!
Bentwings:
Something to be aware of regarding chrome of critical parts. Hydrogen imbrittlement. The chroming process causes hydrogen to be trapped in the pores of the metal. The chemical process is quite complex but be assured it happens. There is a lot of controversity about how to remove it or prevent it. Generally it is believed that if the parts are baked within about 45 minutes for a given time the imbrittlement can be relieved. However not all authorities believe this. Certainly not all shops go to the extra effort.
I think NHRA tech prohibits chrome suspension parts. Do some checking.
Years past the established chrome shops did everything they could to,prevent this but now......??
One of the local funny cars had all new front end pars chromed at a new chrome shop. About 6-8 runs into the new season a spindle broke off the a arm assemble in a burn out. Lucky for everyone only some Fiberglas got bent up. It didn't take a magnifying glass to see the brittle fracture.
Just a heads up

It cost me roughly $23 a foot from the place in tenn. And I picked it up at autofair. Looks good but didn't add any speed to the car.

Did the king pin boss break off the a-arm at the weld or did all three legs of the a-arm fracture? If the boss fell off I would suspect faulty welding rather than hydrogen embritlement.
