This is an aftermarket replacement part for the Grenadier, tested and validated by Agile Off Road. NOT an Upgrade part, replacement part only.
The TeraFlex JL/JT: Factory Replacement Rzeppa CV Joint Kit replaces a worn or damaged factory Rzeppa CV joint, without resorting to a high maintenance and expensive aftermarket U-joint style driveline conversion.
The included low-friction grease is engineered specifically for the high RPM needs of the JK Rzeppa CV Joint and features high-viscosity surface bonding characteristics necessary to properly adhere the grease to all moving surfaces.
