The ARRMA Kraton 8S Carbon Steel Pin by GPM MAKX181/PD uses 4140 carbon steel to deliver robust joints in aggressive driving conditions. These pins are compatible with original and GPM driveshaft assemblies and are intended to maintain a tight connection between the universal joint head and the dogbone, reducing play and improving drivetrain response during hard acceleration and rough terrain use. They are a straightforward replacement for users wanting tougher hardware.
