TKR6851X M6-Driveshaft Kit Front Slash 4x4

The Tekno RC TKR6851X M6 Front Driveshaft Kit is a heavy-duty upgrade designed for the Traxxas Slash 4x4 and other compatible 4x4 platforms like the Stampede, Rustler, and Hoss. It replaces the weak stock front driveline with oversized 6mm stub axles, hardened steel driveshafts, and reinforced drive cups for dramatically improved durability under high power. The design uses a captured CV pin system to prevent parts from popping out during hard impacts, while the larger bearings help handle increased loads more efficiently. This kit also includes upgraded steering blocks that reduce slop and improve steering precision, making it a popular choice for brushless and high-speed setups. Overall, it’s built for serious bashing and racing where stock parts tend to fail.
