New product from Gforce Engineering - Billet pinion yokes

[GFORCE1320]

Gforce Engineering is proud to announce that we now have our billet pinion yokes available for the Camaro and G8 rears.

The new pinion yokes are machined from billet 4340 and use the big 1350 series u-joints.

This is the same billet pinion yoke that we will supply with our Camaro and G8 driveshafts.
The Camaro and G8 pinion yokes are interchangable.

With our billet pinion yokes, swapping to a race transmission like a TH400 or 4L80 is very easy.
Just bolt on our billet pinion yoke and have your favorite driveshaft builder make you a driveshaft or give us a call as we can also supply your driveshaft.








Thanks
Chris @ Gforce

Wow! Those look nice - are they heat treated? What kind of coating/plating are on those things?

Oh yea, heat treated to 48 on the Rockwell C-Hardness scale in our special vacuum fired oven process

We normally coat all our parts in an aerospace process called black e-coat but that line went down so we went with our yellow zinc back up coating process.

Thanks

Nice piece !!

That should keep people from breaking things under hard launch.

Black e-coat is the way to go.... be careful with zinc plate on hardened parts - hydrogen embrittlement can be a concern.

My new billet pinion yokes have arroused the interest of a few driveshaft companies, maybe there will be more driveshaft options here real soon.

You are so right!! I had a guy steal axles from my display that had this done just to look nice,anyway they broke on him and left him stranded LOL!..Im sure chris has this worked out.

[GFORCE1320]

Oh yea, I have it worked out. It's not so much of a problem with 4340 and 300m materials as it is with chromoly.
The temp and process also has alot to do with it.

Thanks
Chris

It's a problem with any carbon alloy steel hardened above 39 Rc including 4340, 300M, Maraging, etc. Just ask the engineers that work on landing gear over at Boeing. A very special and lengthy baking process immediately after plating must be done - even then there is still a concern of hydrogen embrittlement. This is why you will never see plated high strength bolts from a reputable manufacturer.

Yes, I know all this. I am actually an ex-Boeing engineer my self. We use an aircraft spec coating process on our stuff.
Thanks for the heads up though.

Sounds like you're on top of it! BTW- those axles in your sig look incredible Props to having some very cool products.
