2014 precedent rear end ID

[racemrc]

I need to install high speed gears, but I am struggling to ID the rear axle in this cart. I have been told it should be a Kawasaki but also told it is a Graziano. Can someone who has actually done a gear swap help ID this for me? Once identified and gears are ordered, how difficult are they to install and are any special tools required? Also do most go 6:1 or 8:1 ratio? I am planning to rework the clutch springs in order to help offset some of the torque lost from the hearing.

Thanks in advance. IMG_0887.jpg

I don't remember when the change was made, but I wanna say all of the Precedents have the Graziano axle. The second photo with the oval logo is the Graziano logo.

All of the Kawasaki Axles say Made in Japan or Japan on them somewhere.
The Graziano axles usually have a sticker on the axle tube with the serial number for the axle, but those can fall off. And they are usually made in Europe IIRC.

I believe you need a press to install the high speed gears. I think most people just go for the 6:1. The Fe350 engine has enough power to turn them no prob unless you have tires bigger than 20" and are trying to climb big/steep hills, in which case you probably shouldn't be using high speed gears.
