Overview
The Tekno RC HD diff coupler is the heavy-duty version of the brand's hardened steel differential coupler. The coupler carries drive from the center driveshaft into the differential, which puts it squarely in the shock-load path every time the throttle snaps open or the truck lands hard.
Tekno's HD designation means a stouter, hardened steel part aimed at racers and bashers who chew through couplers. If your drivetrain has developed a clunk and the coupler pockets look rounded, this is the piece to swap in.
