The Exotek Rock/Baja Rey Alloy Differential Gear Case is a heavy duty diff cup option that can be used in the front or rear position on Losi Rock Rey or Baja Rey models. The cup uses bigger than stock, steel screws to help prevent blowing out the gear diff under heavy loads. Screws require a quality 1.5 hobby grade hex wrench (do not use allen keys). Losi Rock/Baja Rey gear diff is required.

Exotek Rock/Baja Rey Alloy Differential Gear Case
Bought two of these for my Rock Rey. A lot of machined aluminum parts look nice, my question is always "how well do they fit?"

I'm happy to report these are amazing. Very well machined and everything bolts up perfectly. I'm looking forward to my next Exotek purchase.

Exotek Rock/Baja Rey Alloy Differential Gear Case
Is of good quality and improved my Losi Rock Rey. The stock one was out of plastik and the screws ripp off or even broke.
I had a fitting problem with the screws included but at the end I used a bit more force and then all was good. Will buy an other one just to have it as spare.

Exotek Rock/Baja Rey Alloy Differential Gear Case
These diffs work great. You have to open up counter sunk holes to 2.4 mm that correlates to a 3\32 drill bit. Drill holes on ring gears and transmission gear to allow 2.5x6mm hardware. Directions say to use dremel tool but i found a drill bit works faster. You dont want it to heat up and lose its heat temper.

There is included instruction sheet now that addresses how to correct for the ring gears screw holes being so small. Diff case works perfect! :)

Exotek Rock/Baja Rey Alloy Differential Gear Case
This did not bolt right up for me. The hex screws that come with the diff are just a hair larger diameter than the countersunk holes in the gear(maybe just mine)...and the gear is hardened steel, so it’s not easy to bore the holes out.
