Aeroflow Performance has redesigned the LS oil gallery barbell. Made from Billet 6061 Aluminium we have managed to make the unit smaller which in turn allows more oil flow. This is an important replacement for the factory plastic unit that becomes brittle over time which can lead to it breaking and in turn the motor loses oil pressure.
