Melling 10295 - High Pressure Engine Oil Pump for Gen3 & Gen4 4.8L, 5.3L, 5.7L, 6.0L, & LS3 6.2L

Description

Melling high-performance oil pumps provide dependable performance every time in every application under the toughest RPM conditions. The Melling 10295 high-performance oil pump is engineered as a high-pressure, standard-volume performance upgrade over the factory-style M295 oil pump, delivering a 10% increase in oil pressure without increasing volume displacement. The cast aluminum housing is CNC machined and hardcoat anodized, while the cast iron cover is CNC machined and phosphate coated for superior wear resistance, reduced friction, and long-term durability. Designed with serviceability in mind, the internal pressure relief valve features a screw-in valve plug and includes an optional lower stock-pressure spring to fine-tune your oiling system. Every Melling high-performance pump is individually bench-tested for flow and pressure under simulated engine operating conditions before packaging.

Features & Technical Highlights:

• Optimized Pressure Curve: Standard volume displacement with a 10% increase in oil pressure over the baseline M295 pump, ideal for high-RPM street and competition wet-sump builds.
• Hardcoat Anodized Housing: CNC-machined cast aluminum body provides precise internal clearances and excellent resistance to bore scoring and wear.
• Phosphate-Coated Cast Iron Cover: Rigid cast iron end plate minimizes deflection under high pressure and enhances surface wear life.
• Adjustable Pressure Relief Valve: Features a threaded screw-in plug for secure retention and includes an optional lower stock-pressure spring to match bearing clearance demands.
• Factory Pickup Compatibility: Designed to bolt directly to standard 1-1/4" bolt-on oil pickup tubes.
• Complete Sealing Kit: Includes replacement oil pump and pickup screen mounting O-rings/seals for a clean, leak-free installation.
• 100% Factory Bench Tested: Individually flow- and pressure-tested under realistic engine operating conditions to ensure flawless out-of-the-box reliability.
• Application Compatibility: Direct fit for wet-sump GM Gen III and Gen IV LS engines; cannot be used on factory dry-sump LS7 and LS9 engines.
