I bought this since I could not find a 22-RTR gear diff. This is a very sturdy differential. I put this in my 22T 2.0MM 3-gear setup to race at my local carpet track. This diff is heavy. 59 grams compared to 37 grams of my ball diff. I bought this since it was much cheaper than aluminum race gear diff(TLR332067). I can't complain about weight since this is not intended for racing. What I can say is it will last a long time and could work well on dirt track since it will put more weight in the back. I would not run this in a 17.5 race car. I swapped out the fluid that was pre-installed with Team Associated 4k fluid and it does not leak.

This is second drive I have had ti replaced because of. The out drive has chipped out where the dog bone pins engage on the outdrive. The internal parts are great, Sturdy, no questions,bout the quality of the internal gears. The material that they are using for the outdrives is either too hard that it gets chipped from the dog bone pins pounding on it. Every time you're on and off the throttle , I wish they would improve harding process or heavier duty metal, and differential assembly would be awesome. Maybe Losi can come up with a better outdrive material.

Used it on my 22s Drag and I had no issues with the fit.

I bought this to replace the diff in my 22S sct, since this is exactly what comes in the truck. A bearing had come apart chewing up the teeth in the main gear, sounds like this has happened again. the outdrives are really weak and have developed flat spots very quickly. Its too bad everything from Losi is junk these days.

What reviewers say

Reviewers agree the internal gears and differential assembly are sturdy and fit well in 22-series trucks and drag setups, and one reviewer reports no leaks after changing the pre-installed fluid. The main recurring problem is the outdrives: two reviewers report chipping or flat spots where the dog bone pins engage, and one reports a bearing failure that damaged the main gear teeth. One reviewer notes the unit is heavy (59 g versus 37 g for a ball diff) and says it is not suited to 17.5 racing, though it may suit dirt track. Opinions are split between praise for durability and complaints about outdrive wear and overall quality. The sample is small, with four reviews.

  • + Sturdy internal gears
  • + Good fit in 22-series setups
  • + No leaks after fluid change
  • + Lower cost than aluminium race diffs
  • − Outdrives chip or develop flat spots
  • − Bearing failure damaged main gear teeth
  • − Heavy compared with ball diffs
