The GPM MGG048FS Front CVD Drive Shafts are precision manufactured from 4140 medium carbon steel with a hardened black surface treatment to resist abrasion and bending under load. The unit uses CNC machined steel wheel stub axles to replace the OE CVD dog bone and plastic wheel shafts, improving torsional rigidity and component life. These drive shafts are designed for hobbyists seeking a durable, maintenance friendly upgrade that keeps driveline geometry consistent during heavy use.
