Big Rock Wanting to upgrade to metal diff and input gear.

My question is are these the correct part numbers that I have in my Amazon cart. To me it looks correct but figured I’d ask the community.

Yes, but can save some coin using Jennysrc. Go to kraton 4s parts. Same diff is $29.00.

 

[kaladeth]

Yes. Curious how did you get the part numbers in the first place?

You can always check “fitment” on the Arrma website:

A metal yoke would be good too.

You might want to check Jennys too.

When I did a surge, I did not have the part numbers. I just went on Amazon and typed Arrma metal diff

You want the aluminum red yoke so you the gears don't miss align under throttle. Plastic stock yoke flexes causing the gears to go out of alignment.

I can attest to the fact that the above hot racing yokes work. Have them on both typhons.

The metal diff set has the input gear in it already.. definitely do the metal yolk while your at it and make sure you grease the gears! I only did metal in for the rear axle and been bashing for a few months on 4s, not one issue

Same here, the aluminum yokes keep the mesh correct on the diff and input gear (less flexing). I put one of these on my Granite with the plastic diff and no issues yet.

Sorry they didn't work for you. Mine have been flawless.

No issue's here gears all lined up nice. Maybe you got a bad one?

Maybe you got a bad one. I have two with hr diff cup and gears no problems.
