The GPM MAK142FS Harden Steel Front CVD Driveshaft is designed to reinforce the ARRMA Kraton 6S BLX front driveline with a focus on reliability and long term durability. Manufactured from hardened steel #45, the component provides higher resistance to wear and deformation. Increasing the dogbone diameter from 5mm to 6mm reduces joint deflection and improves torque transfer under load.
