Melling Performance 10296 High Pressure LS Oil Pump - High Volume

Melling 10296 High-Pressure High-Volume Oil Pump

Compatible with: Gen III & IV LS1, LS6, LS2, LS3, LQ4, LQ9, LR4, LM7, L59, LS4, 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L engines

The 10296 high-performance oil pump provides an 18% increase in oil flow compared to the standard volume 10295 pump. It retains the same design enhancements introduced in the 10295 model, ensuring improved efficiency and reliability. Specifically engineered for high-performance LS applications, this pump meets the increased oil flow demands of modified and high-RPM engines. Designed for GM Gen III and IV engines, it offers direct-fit installation with no modifications required.

• Exclusive high volume (+18%) rotor design
• Hard coat anodized aluminum housing
• Phosphate coated cast iron cover
• High pressure (+10 psi) spring installed
• Includes optional standard pressure spring
• Threaded pressure relief nut
• Uses 7/8” stock bolt-on oil pickup tube assembly
• Includes O-rings for oil pickup tube assembly

Performance Benefits:

The stock LS oil pump experiences cavitation above 6,200 RPM, reducing oil flow by nearly 1 GPM at 7,000 RPM and aerating the oil, leading to pressure drops and potential oil starvation. This upgraded Melling pump is recommended for engines operating above 6,200 RPM to prevent these issues. It also helps maintain stable oil pressure in setups with oil coolers.

Application Compatibility:

This oil pump is designed for GM Gen III & IV LS and Vortec engines without Active Fuel Management (AFM) or Displacement on Demand (DoD). For AFM/DoD-equipped engines, see Melling part number 689-10355.

Supported Engines:

Gen III LS Blocks:

• LS1, LS6

Gen IV LS Blocks:

• LS2, LS3

Gen III Vortec Engines:

• 4.8L (LR4, LM7)
• 5.3L (LM7, L59, LM4, L33)
• 6.0L (LQ4, LQ9)

Gen IV Vortec Engines:

• 4.8L (LY2, L20)
• 5.3L (LH8, LH9)
• 6.0L (L98, L96, LY6, L9H)
