Dasbecan High-Volume M29-5HV Oil Pump Kit for GM Vortec V8 (4.8L–6.0L) — +18% Flow, +10 psi

Dasbecan High Volume M29-5HV oil pump kit is a direct-replacement, high-volume/high-pressure oil pump designed to increase oil flow and pressure for GM Vortec V8 engines.

If you run a GM 4.8L, 5.3L, 5.7L or 6.0L Vortec engine and want improved lubrication performance under high RPM or heavy load, this Dasbecan M29-5HV kit upgrades oil delivery while matching OEM fitments. The kit replaces several common OEM part numbers and arrives with necessary gaskets and a balancer bolt so you can swap the pump with minimal additional parts. It’s engineered for greater flow and pressure without altering installation steps or engine geometry.

How does this pump improve engine oiling at high RPM?

The Dasbecan M29-5HV increases both volume and pressure compared with a standard pump to deliver more oil when the engine demands it most. That additional flow helps maintain oil film and cooling at elevated RPM, reducing the risk of oil starvation in highly stressed valve trains and bearings. It’s not a replacement for proper maintenance, but it gives extra lubrication capacity for performance or heavy-duty use.

• Approximately 18% higher oil volume versus standard pump
• About 10 psi higher pressure at comparable engine speeds
• Designed to maintain oil film under high RPM or load
• Direct replacement geometry for correct clearances

Will this fit my Chevy or GMC Vortec V8 engine and which parts does it replace?

This high-volume oil pump is made to fit GM 4.8L, 5.3L, 5.7L and 6.0L Vortec V8 engines used in a wide range of Chevy, GMC and related vehicles from late 1990s through later model years. The kit is intended as a drop-in replacement for multiple OE numbers so you can swap without modifying the front cover or oiling passages. Always verify compatibility by checking your engine code and year against the fitment list before purchase.

• Replaces M29-5HV, TCS45993, 12557840, 12696357 and similar OEM numbers
• Compatible with Silverado, Sierra, Suburban, Tahoe, Yukon, Avalanche and many GM platforms
• Includes gaskets TCS45993 and balancer bolt 12557840 for a complete install
• Check model and year details to confirm exact fitment

How reliable and long-lasting is the Dasbecan pump compared to stock pumps?

Dasbecan builds this high-volume pump to meet OEM standards for durability and dust resistance while boosting flow and pressure. Materials and tolerances are selected to provide stable performance and longevity under normal and elevated operating conditions. Proper installation and regular oil/filter service remain essential to maximum life expectancy.

• Manufactured to meet OEM dimensional and material standards
• Seals and machining designed for dust and contamination resistance
• Direct-replacement fit reduces risk of installation error
• Recommended with regular oil service for best longevity

What does the kit include and are any special tools or modifications required?

The Dasbecan M29-5HV kit ships as a ready-to-install package with the pump, required gaskets and the balancer bolt so most installs mirror the factory replacement process. No special engine modifications are necessary because the pump maintains OEM mounting and drive relationships. Basic mechanic tools and a service manual for torque specs and installation sequence are advised.

• Includes high-volume pump, gaskets (TCS45993) and balancer bolt (12557840)
• Direct-replacement: no machining or oil passage changes needed
• Typical install requires standard hand tools and torque wrench
• Follow vehicle service manual for proper torque and priming steps

Who is this for: The Dasbecan M29-5HV high-volume oil pump kit is aimed at owners and technicians running GM Vortec V8 engines who want increased oil flow/pressure for high-RPM performance, towing, frequent heavy loads, or enhanced valve-train protection. It’s also suitable for restorations or maintenance where a robust, direct-fit replacement is preferred over a stock-capacity pump. Verify fitment against your vehicle and install using standard procedures for best results.
