Ultimate Reliability for GM LS Engines

Protect your investment with the Boundary Pumps Billet Oil Pump Gear Set. Designed specifically for GM LS-series engines, these gears replace brittle factory powdered metal components with high-strength, precision-machined chromoly steel. Whether you are building a street machine or a track-focused engine, these gears provide the peace of mind required for high-RPM operation.

Key Features & Benefits

• Precision Engineering: CNC-machined from 4140 chromoly steel for superior durability.
• Polished Finish: Reduces friction and promotes smoother oil flow through the pump housing.
• Standard Flow Design: Maintains factory oil pressure specifications while increasing structural integrity.
• Direct Fitment: Engineered to drop into standard GM LS oil pump housings without complex modifications.

Factory oil pump gears are a known weak point in high-performance LS builds. By upgrading to Boundary Pumps billet gears, you eliminate the risk of catastrophic gear failure during aggressive driving. These gears are heat-treated to ensure maximum wear resistance under extreme thermal loads. If you are performing a cam swap or a full engine rebuild, this is an essential upgrade for long-term engine health. Trust your lubrication system to the best components available at GGCRACING.
