Three zero-mile builds for the Gen IV 6.2L GM V8 (L92 / L9H / L94 / LS3 / L99 and related) — from an OEM-spec replacement to a Fraser Advantage™ DOD/AFM delete. Every option ships with no upfront core fee and free core pickup.
Inventory is refreshed every 15 days; availability may change during update periods.
Core Policy: This unit requires a returnable core. Free pickup is arranged by Fraser Engines.
Optional 1- to 5-year No-Fault Warranty can be added at checkout — one free replacement no matter the cause. See No-Fault options.
Recommended bundles: Break-In Fluid ($47.99) and Premium Installation Kit ($250).
Fraser Engines has identified that many Active Fuel Management (AFM) lifter failures are not due to defective parts, but rather issues with oil pressure or oil control within the system. Our testing has shown that a majority of returned AFM lifters function properly when evaluated under correct operating conditions.
The AFM system operates within a normal oil pressure range of 27 PSI to 66 PSI. Activation and deactivation of AFM lifters are controlled by the Valve Lifter Oil Manifold (VLOM), which directs pressurized oil to the AFM lifters when cylinder deactivation is commanded and stops that flow to reactivate the cylinders.
In several warranty cases, AFM lifters have been found stuck in a compressed position. This condition is often caused by the VLOM commanding activation or deactivation at the wrong point in the camshaft rotation, such as during the ramp or at the lobe peak, rather than a fault within the lifter itself.

Extend to a 2- to 5-year No-Fault plan at checkout — see options. Recommended bundles: Break-In Fluid and Installation Kit.

The AFM system operates between 27 PSI and 66 PSI and is controlled by the Valve Lifter Oil Manifold (VLOM), which directs oil pressure to activate or deactivate lifters.
Failures often occur when the VLOM commands activation at the wrong camshaft position, causing lifters to become stuck — this is not a defect in the lifter itself.
A 6.2L DOD Delete Engine is a modified version of the original 6.2L GM engine where the Displacement on Demand system, also known as Active Fuel Management, has been removed. This improves long-term durability by eliminating the frequent cylinder activation and deactivation that can contribute to premature lifter, camshaft, and valvetrain wear.

What even is a NO FAULT warranty, and why would you need it if the engine already has a warranty for free? The standard warranty covers defects in the engine. A No-Fault plan gives you one free replacement no matter the cause of failure — installer error, overheating, oiling problems, anything — plus labor reimbursement at published book time.
Labor reimbursement uses published Mitchell or AllData times. One-time replacement applies per covered unit during the elected term.
Specially formulated to protect your new engine during the most critical phase of its life — the initial break-in period. Designed to promote proper ring seating, reduce friction, and prevent premature wear, this high-performance fluid helps ensure maximum longevity, smoother operation, and optimal performance from day one. Trusted by engine builders and recommended by Fraser technicians.
Highly recommended for every new engine installation.
Designed to streamline your engine replacement while protecting your investment from day one. This all-inclusive kit replaces the most commonly worn supporting components that can affect performance, cooling, and reliability after installation.
⚠️ Availability may vary by application. Please confirm availability during order confirmation to ensure this kit can be added to your purchase.
The 6.2L GM V8 engine, part of the Gen IV small-block family, is widely known for its power and performance in trucks, SUVs, and performance vehicles. While reliable, this engine has some common issues that Fraser Engines addresses through precision remanufacturing and key technical updates. These improvements enhance durability, performance, and overall reliability.
Why? Lifters associated with the Active Fuel Management (AFM/DOD) system are prone to failure, often damaging the camshaft.
Update: Fraser replaces all lifters with upgraded, non-DOD versions for DOD delete applications, and installs a high-strength camshaft for improved durability and smoother performance.
Why? The AFM system’s frequent activation/deactivation of cylinders can cause excessive wear and oil consumption.
Update: Fraser offers a DOD delete option, which includes updated lifters, camshaft, and tuning recommendations to eliminate AFM and provide consistent cylinder operation.
Why? Factory cylinder heads can develop cracking or warping under high stress or temperature.
Update: Cylinder heads are thoroughly pressure-tested, resurfaced, and upgraded with hardened valve seats and guides to ensure reliability.
Why? The factory pistons and rings are prone to wear, leading to oil consumption and reduced compression.
Update: Fraser uses pistons with advanced coatings and upgraded rings to improve sealing and reduce oil consumption.
Why? Insufficient oil flow can lead to lifter and camshaft wear.
Update: A high-capacity oil pump is installed to ensure consistent oil flow and proper lubrication.
Why? Timing chain stretch and guide wear can lead to timing misalignment and engine noise.
Update: Timing chains, tensioners, and guides are replaced with heavy-duty components for precise and long-lasting operation.
Why? Direct injection engines like the 6.2L are prone to carbon deposits on intake valves, reducing performance over time.
Update: Intake ports are cleaned, and preventative measures are taken to reduce future build-up.
Why? Overheating can cause head warping or gasket failures.
Update: Cooling passages are optimized, and Fraser recommends using upgraded thermostats and water pumps for better heat management.
Why? An unbalanced crankshaft, rods, or pistons can lead to vibration and premature wear.
Update: The crankshaft, rods, and pistons are precision-balanced to reduce vibration and ensure smooth operation.
Why? Oil and coolant leaks are common in older engines.
Update: Fraser uses premium-grade gaskets and seals to eliminate leaks and enhance reliability.
Why? High-performance applications can stress factory components, leading to failure.
Update: Stronger valve springs and rocker arms are installed to handle higher RPMs and heavy loads.
