Solid piece of hardware
- October 27th 2020
Feels super high quality, and its lighter than the Hot Racing diff. I only give it 4 stars though because it comes with shims and no instructions or note as to where the shims go.
Simply the best

I have went through many diff and locker combinations. And when I say "went through" I mean "destroyed". but this diff with the suggested spider gear set has lasted longer than any other combination I've had. I've rebuilt it once andread more
Nice Quality

Nice quality only downside for me is gears stripping, I've rebuilt 5 times each with new gears and tried different diff oil viscosity's with no luck...
wow!!!!

if you have you to choose one thing that I would call an essential upgrade, this is it!!!! I only added this b/c I just needed something to do. However, after installing this, I cannot believe how much better my stampede and my rustler run. Absolute muread more
Good stuff
- February 23rd 2013
Installed this in a 4 degree tranny. Super impressed with handling and tuning. Been using 100K oil, performs like a locked diff when you need it, yet will still diff out when a wheel is stuck.
Great upgrade

Makes a huge difference in handling, i put 7k diff fluid in it and it makes for a completely different animal, I highly recommend it!! It is red anodized now too
