The TKR5572 Hardened Steel CVD Driveshaft Set is a pair of replacement constant velocity (CVD) driveshafts designed for Tekno RC 1/10 scale SCT410 short course truck platforms, and is also compatible with related Tekno 1/10 vehicles such as the SCT410 and SCT410.3. These driveshafts are made from hardened steel for high strength and durability, allowing them to handle heavy loads and high-power setups while maintaining smooth, consistent power transfer through the suspension cycle. Each set includes two shafts that can be used for either the front or rear position depending on configuration, making them ideal for maintenance, rebuilds, or drivetrain upgrades on compatible Tekno SCT-based chassis.
