Melling 10295 Standard Volume, High Pressure LS Oil Pump

[Part # 10295]

$109.99 Free Shipping Details
Qty:

The factory LS oil pump suffers from cavitation above 6,200 RPM, which results in a drop in oil flow of nearly 1 GPM by 7,000 RPM. This cavitation can also aerate the oil, which causes drops in oil pressure and can result in oil starvation. This is why we do not recommend shifting any higher than 6,200 RPM with a stock engine. Engines that run at RPM's above 6,200 should use an upgraded Melling pump to prevent these issues.

The Melling 10295 pump features a stiffer pressure relief spring, which increases the maximum system oil pressure by 10%. This higher maximum pressure can help negate drops in oil pressure caused by the addition of an oil cooler setup. The stiffer oil pressure relief spring can be swapped out for a factory specification spring, which is also included with the pump.

This oil pump is compatible with 4.8L and 6.0L Vortec iron block engines featuring Variable Valve Timing (VVT). This oil pump should not be used with engines that feature Active Fuel Management (AFM). Engines with AFM require a higher flow pump. See Melling part number 10355.
