Boundary A853-S1 High Flow Oil Pump Assembly for Dodge SRT4 2.4L

The Boundary A853-S1 is a high-performance oil pump assembly engineered specifically for 2003-2005 Dodge Neon SRT4 and 2001-2010 PT Cruiser 2.4L engines. This precision-built pump assembly features a brand new housing that has been blueprinted and assembled with Boundary's industry-leading billet oil pump gears, delivering superior strength and reliability over factory components.

Performance Features:

• High-flow gerotor set flows approximately 20% more than OEM for improved lubrication
• Billet steel gears rated comfortably at 8000 RPM (standard) or up to 13000 RPM (MartenWear option)
• Customizable relief valve with 5 different set point options
• Mirror-finished gear set for reduced friction and increased efficiency
• Provides superior oil pressure earlier in the RPM range for better bearing protection

Quality Construction:

• Complete ultrasonic cleaning, air blast, and hand inspection of all components
• Hand de-burred pump housing to reduce turbulence and maximize flow
• Stainless steel Torx head fasteners replace stock hardware
• All fasteners torqued to specification with Loctite to prevent loosening
• Anaerobic sealant applied to critical areas for faster pump-up speed and reduced aeration
• Assembly lubricant applied to all critical surfaces for immediate oil flow on startup
• Parts blueprinted and issued with specification sheet documenting clearances

Manufactured in-house in Dallas, Texas, Boundary oil pumps are constructed from billet steel providing nearly 110,000 PSI yield strength compared to less than 6,000 PSI from OEM powdered steel components. This makes the A853-S1 ideal for high-performance street and track applications where engine reliability under extreme conditions is critical.
