2019+ YXZ Rear Diff: Is it relatively bulletproof?

RobBeck · Nov 12, 2021

Have a 2019 YXZ SS SE and it is pushed pretty hard, and am trying to collect spare parts so I never get left hanging with a commonly broken part without a replacement on hand. I've around 1200 miles on the machine to date, it has been rock solid thus far. The question is has anyone been known to break the rear diff, or this something that would be good to carry in a spare parts bin just in case?

I do plan on installing the GYTR Turbo kit in the spring as well, something else that will certainly push it to the next level as well.

I would think it would have been made pretty tough with the Yxz having launch control standard. Once you add a turbo everything wears a lot quicker!

Definitely concerned about the additional power, and trying to plan ahead. The rear diff is not exactly cheap, but if it is something that has some significant chance for failure it would be best to get it on order sooner than later.

Are we talking .22lr or .50 raufoss? I have a 16’/stock gears:GYTR turbo. Couldn’t keep the rear drive together. 5x axles, 3x old diffs, alba carrier and a driveshaft. I’ve had the 19’ diff for about 500mi now. The main difference is the steal bearing carrier. I just installed stage 2 axles, so I guess we’ll find out which one breaks first 🤣
I have 29x14x14 sand slinger tires on 11” wide rims. We play cut the paddles 50/50 to help reduce drivetrain stress. Doesn’t win any holeshots, but gave alot more top end and the car floats the sand really well with the big wide tires.
About the only reason I haven’t pulled the front drive is so I can still make it back when something in the rear breaks.

Definitely sounds like you have put the older parts through the wringer which didn't hold up too well in the process, but the jury is still out what you will do to the newer unit so keep us posted. Have you heard of anyone having problems with the '19+ units being weak links in any way yet?
