So my real question is: Do you feel that the cheap one is still "stronger" than the oem one in terms of the shaft breaking or not breaking?

Good question. Don't know the OEM material [or the china or Skunk for that matter] so making an assumption they're all basically the same steel it comes down to shaft cross-section right?

I'll try and dig out an OEM one to compare later today.

I just measured my stock 99-05 throttle body shaft. I am getting about .345 or 8.76 mm. So it looks like the cheapo and the skunk turd are all slightly larger in diameter. Again, no idea about the OEM material, or the others for that matter.

I have to admit the shipping from China was pretty quick. I got mine yesterday, and I can tell you it looks like crap. As stated above, the finish is terrible, machine marks everywhere but the most annoying part is all the chips inside the threaded holes.

I'll be taking it apart and posting up my findings in a bit.

Here are some pictures.

I couldn't fully disassemble the throttle body, there's a gasket that's stuck inside the bore where the throttle plate shaft goes through, and the stupid spring is stuck.

From a super quick inspection, the throttle plate ranges from ō64.47MM to ō64.54MM, the shaft is steel, I just don't know if it's hardened (I have some hardness files around here somewhere.)

This appears to be the bearing: https://www.fastenal.com/products/details/4126357 from the part number

Also, spring pressure seems the same although I havenít checked with a guage.




4. Butterfly shaft
Hereís where the 2 products differ significantly.

Cross shaft ō:
SKUNK2 10.88
China TB 9.71

Across shaft flats:
SKUNK2 6.8
China TB 6.8
My Junk2 throttle cable cam thingy is made out of aluminum, which can be seen here.



Here are the dimensions I got from my shaft.

I question how strong the pulley really needs to be. Nylon will probably outlast my car.

Proof enough that it's a cheap copy, not the real thing at less cost. Hard pass.

QFT

And a heads up: some really good prices on the genuine Junk2 99-05 TB on Amazon right now.

M6x1.0 button socket head. Probably shallow thread length.

I got mine the other day- took 7 weeks and at one time was thought to be lost. Anyhoo, it looks pretty good. A little different than the others, machine marks were acceptable and the throttle cam is aluminum not plastic. The throttle shaft also measures about 10.5 mm in dia. Raw aluminum it looks like. I did not see any color options at the time either. Trade me for that black one?

Thanks for the offer but I dont mind the black.

Word of advise to anyone who hasn't installed theirs yet. Bring your idle control valve with you when you go get the button head screws. They only supply one screw and the other will need a slightly longer one than whats on the factory TB. Also the supplied TB to manifold gasket is cut wrong.
