Boundary A853-OPG-M High-Flow Billet Oil Pump Gear with MartenWear Treatment

The Boundary A853-OPG-M is a precision-engineered high-flow billet oil pump gear designed for 2003-2005 Dodge SRT4 A853 2.4L I4 turbocharged engines. This performance upgrade replaces the factory powdered metal gear with a superior CNC-machined chromoly steel component that delivers enhanced durability and reliability in high-horsepower applications.

Advanced Manufacturing Process:

• 100% manufactured in Boundary's Dallas, Texas facility
• CNC-machined from USA-sourced chromoly steel billets
• Quenched from extreme heat and tempered to create an indestructible core
• Treated with proprietary ColdFlow surface hardening process
• Enhanced with MartenWear heat treatment for superior wear resistance
• Mirror-polished finish for reduced friction and optimal performance

Performance Features:

• Rated for extreme RPM operation up to 13,000 RPM
• Proven reliable in applications exceeding 1,000 wheel horsepower
• Higher efficiency and lower friction compared to factory gears
• MartenWear treatment tested to 15,000 RPM without wear
• Maintains full oil pressure even under extreme racing conditions

The MartenWear treatment sets this gear apart from standard billet offerings, providing an ultra-hard, wear-resistant surface that virtually eliminates gear breakdown. This makes the A853-OPG-M ideal for turbocharged builds, forced induction applications, and high-RPM racing use where factory components simply cannot survive. Backed by Boundary's industry-leading warranty, this oil pump gear is essential protection for serious performance builds.
