TKR6855 Big Bone Center Driveshaft & Outdrive Kit (Slash 4x4)

The TKR6855 Big Bone Center Driveshaft & Outdrive Kit is a complete center driveline upgrade designed for the Traxxas Slash 4x4, Stampede 4x4, and related 1/10 Traxxas 4x4 platforms. It replaces the stock telescoping center shaft with Tekno’s oversized “Big Bone” dogbone-style shaft, along with hardened steel front and rear outdrives for significantly improved durability. The large-diameter aluminum shaft is lightweight yet much stronger than stock, and its dogbone design helps eliminate common issues like binding, twisting, or splitting under high power. This makes it a popular upgrade for high-speed, brushless, and heavy bashing setups where the factory driveline is a known weak point.
