This is the Traxxas Complete Rear Differential for 1/10 4x4 Slash, Hoss, Stampede, Rustler, and Rally. This complete, pre-assembled diff is a great part to quickly repair a damaged driveline, and a great spare part to have on hand too.
The Pro-BUILT 4X4 rear differential comes professionally assembled for easy drop-in replacement. The sealed assembly comes pre-filled with 30k-weight silicone oil with steel gears to withstand Velineon brushless horsepower. Pro-BUILT differentials are direct replacements for VXL 4X4 models (see full list below). Includes 13-tooth pinion gear and 37-tooth ring gear. Pro-BUILT differentials are not directly compatible with Titan-powered 4X4 models.
