Aeroflow's replacement billet oil gallery barbell is designed to suit GM LS series blocks and provides a stronger, more reliable alternative to the factory plastic component. Manufactured from billet 6061 aluminium, this upgraded plug is engineered to improve durability while maintaining precise fitment in compatible LS engine applications.

The redesigned smaller profile helps allow more oil flow through the gallery system, supporting proper lubrication performance where it matters most. The original plastic barbell can become brittle over time and may crack or fail, which can lead to a loss of oil pressure and serious engine damage. This billet replacement is a smart preventative upgrade for engine builders, performance enthusiasts, and anyone servicing an LS platform.
