Complete Differential Assembly w/ 500k Oil - 9480

Lock in straight-line traction right out of the package with this heavy-fluid differential assembly.

Built specifically for high-traction launches and no-prep drag racing, this complete differential assembly comes factory-sealed and pre-filled with ultra-thick 500k weight silicone differential fluid. It delivers heavy resistance to keep both rear tires driving hard off the starting line without sacrificing the tuning convenience of a sealed gear diff.

Originally equipped as standard equipment on the Traxxas Drag Slash, this drop-in unit installs directly into any Magnum 272R transmission case. It comes fully built with 10x15 mm ball bearings included, saving you the mess and time of assembling and sealing a heavy-fluid diff on your pit bench.
