Rear knuckle question
What is the part number for the upper control arm bushing on the knuckle? I have looked and found no clear answer. Or what is the best upgrade for the knuckle bushings?

I don’t think that is considered a serviceable item by GM. Don’t know about the aftermarket. I replaced my knuckles with Z28.

Yeah the whole knuckle is only 110 bucks for the SS. The Z 28 ones are discontinued, what else is out there after market?

The UPPER and LOWER bushings in the Knuckle are SPHERICAL bushings. There
are no replacements, unless you have a 16+, and they're $500+ for the set. There is a thread on this already, I am not typing it all in again... Those bushings help retain camber angles with cornering. If you can find any POLY or RUBBER replacement, it will work, but you will feel the difference. Also the UCA inner bushings is also Spherical, and there is a POLY replacement for that. |

I think the part about spherical bushings is only for the Z28 knuckles.

I have a V6, and they're spherical, and so is the inner UCA. I mean, you can SEE the difference, and you can pivot the spherical ones with your hands! If you can't see the difference, well, then good luck to ya... ALL the Gen5s have them in the same spots. They are in the knuckle specifically for wheel track; to keep the most tire on the ground under all conditions. |
