Anti-Refuns Technical Notice: Low oil pressure after installation is often caused by a pinched or incorrect oil pick-up tube O-ring. Ensure the O-ring is seated perfectly within the pump inlet. This M295 kit is designed for standard street applications. If your vehicle has high-mileage wear or high-lift camshaft modifications, verify if a high-volume pump is preferred. Installation Requirement: The included balancer bolt must be tightened using the torque-plus-angle method as per the factory service manual. Failure to follow this physical installation protocol may result in harmonic balancer slippage or crankshaft damage.

• FIT for 1999-2013 Chevrolet Silverado, Suburban, Tahoe, Avalanche, and GMC Sierra, Yukon, Savana equipped with 4.8L, 5.3L, and 6.0L V8 engines. This oil pump kit also FIT for LS1, LS2, and LS6 engine platforms. Direct replacement for part numbers M295, 12696357, 12586665, and JV5158. Please verify your engine does not require a high-volume pump for AFM/DoD systems before purchase.
• This engine oil pump kit includes a standard volume oil pump, a timing cover gasket set, and a critical crankshaft balancer bolt (OE 12557840). The M295 pump utilizes a precision-machined sintered iron gerotor and cast aluminum housing to maintain factory-spec oil pressure. The included TTY (Torque-to-Yield) balancer bolt is an essential single-use hardware for secure harmonic balancer installation.
• Designed to restore oil circulation closed-loop to the bearings, camshaft, and lifters, resolving symptoms such as low oil pressure warnings and abnormal engine ticking noises. The timing cover gasket set provides a high-integrity seal to prevent front-crankcase oil leaks. This kit ensures a precise geometric match with the factory oil pick-up tube and mounting points.
• Engineered for 12V automotive oil systems, every M295 pump undergoes dynamic pressure testing to ensure it meets OE flow specifications at both idle and peak RPM. The 12.9 grade balancer bolt provides the necessary clamping force for the crankshaft pulley. The non-PVC gasket materials are selected for chemical resistance against modern synthetic motor oils and extreme thermal cycling.
• Installation Limit: Professional installation is required as this involves timing component access. Strict Exclusion: Not recommended for high-performance engines with Active Fuel Management (AFM) or Displacement on Demand (DoD) unless a standard volume is explicitly required. The crankshaft balancer bolt is a one-time-use fastener; do not reuse the old bolt. Always prime the pump with clean oil before initial engine start.
