Rb4276 803 Posted July 27, 2022 Is this the correct bevel gear set 51008 to fit for the diff cups 53790 to convert my other gearbox of my evo? I purchased months ago and can’t remember. I would rather not open them if they are wrong. What gear set do I need? Is it 50529? I have an extra set of them too. Share this post Link to post Share on other sites

Rb4276 803 Posted July 27, 2022 That is the problem I literally get different responses and different part numbers from various people. I wanted to use the diff cups in the photo because they dont have the grooves like the other ones I used for my first gear diff conversion. They are also $15 as opposed to a few bucks. I was told these lock in and won’t round/strip like what happens to the ball diff and possible again with the gear diff conversion. Share this post Link to post Share on other sites
Rb4276 803 Posted July 27, 2022 The first ball diff I converted I used these parts 50529 gear set, 53218 touring car hard joint cup & 50602 bevel gear set. Obviously I could use them again but these other parts I first posted I was told are better and because the diff cups dont have those ribs that can wear or strip and this lock in better.

GTodd 1350 Posted August 28, 2022 Just buy the Mantaray differential parts. I’ve ran nothing but brushed modifieds and high horsepower brushless in my childhood TF and never melted or stripped differential parts, what the heck are you all doing to your Top Forces? Full throttle to reverse? Wheel stands? 3s power? Share this post Link to post Share on other sites

He said the same as you that they thrashed theirs, unless that was you on there lol. I find it odd that my rear ball diff is perfectly fine and the front failed.
