This is a pack of two replacement XRAY V2 Rear Diff Outdrive Adapters for use with the optional V2 Rear Differential XRA355005. These outdrives are made of HUDY Spring Steel and are CNC-machined on precision German long-turn machines. Additionally ground and strategically lightened to reduce rotating weight, then further hardened to ensure maximum strength and extra-long lifespan. Final precision hand-grinding ensures a very high tolerance to ensure an ultra-smooth tight fit in the diff body and diff gear.
