This is a pair of (2) axles (driver's side and passenger side) designed for 2002-2006 Acura RSX Type-S with Manual Transmission. These axles are upgraded from the factory and have been tested to be able to withstand 250 bhp. They are designed for the Type-S model ONLY and cannot be used with the base or premium model RSX. These axles are forged from heat treated steel alloy and upgraded hardened CV Joints. They also feature an OEM style vibrational dampener in the center of the shaft in order to decrease vibrations from the transmission upon hard launches which can cause premature wheel bearing failure.
