Redcat BS803-025A Front/Rear Complete Diff Gearbox Unit Shredder
I was happy to see the quality of the case and the main and pinion gears. The gears are hardened and that is a must have for this vehicle. The issue I see is the spider gears inside the differential itself are all low quality steel and they don't last very long. I have some old gearboxes I used the spider gears out of and that solved my problem. All in all I'm happy with the product due the low cost.
