Granite Metal pinion and spur for the Granite, oh my!

[Notorious J]

You see, when you park trucks for a long time, you miss out on cool stuff because your not looking for them. Well, after toasting a rear pinion doing wheelies up and down a parking lot with my Granite, I finally did some research. Wouldn't you know, there's a 37t pinion/spur combo that should alleviate that issue going forward. Who knew that the 4s line comes standard with metal gears! (probably everyone but me) Problem is, I've still got a few Jennys pinions and rear difs I have to blow through before putting this bad boy in. Oh well

Leave the extra plastic diff and pinion for the front and slap that metal in and FORGET ABOUT IT

FYI , the 4s has the metal gears but Arrma also sells CNC machined upgrade diff gears also.

That's the plan for sure. Front sees little to no wear, so I'll have spares for life.

Now Mike, you asking me to spend more money? What kind of a friend are you

Just repaying the favor when you convinced me to buy a Fireteam and Mojave EXB (I don't regret either)

I had the idea the CNC stuff is discontinued.

@Notorious J welcome to the metal diff club!

Inputs are still showing in stock on the Arrma site but the crown gear says backordered.

do you have the part numbers for these? Are they from a Kraton 4s?

Those are steel gears used on the Kraton 4s, but not the cnc gears.

 

[AaronF]

thanks for pointing that out, bit of a difference.

 

[Neelis]

Normal steel gear are fine BTW

It can't be the wrong one?
