Do not attempt to reuse old bolts, as they will not provide the necessary clamping force.<br><b>LIFTER ARRANGEMENT:</b> Ensure the <b>8 AFM</b> lifters are installed in the specific cylinders (usually 1, 4, 6, 7 on GM 5.3L) designated by your vehicle's engine code.<br><b>CLEANLINESS IS VITAL:</b> Before installation, ensure all oil passages are flushed. Sludge or debris in the oil is the primary cause of AFM lifter failure.<br><b>VLOM RECOMMENDATION:</b> We strongly recommend inspecting or replacing the <b>VLOM (Valve Lifter Oil Manifold)</b> under the intake manifold when replacing lifters to ensure proper oil pressure to the AFM system.</p> <p><b>Additional Info:</b><br><br><b>Professional Install Recommended:</b> Due to the complexity of the AFM system and the precision torque sequences required, professional installation is highly advised.<br><b>VIN Matching:</b> If you are unsure if your 5.3L engine has AFM (Active Fuel Management), please send us your <b>VIN</b>, and we will verify compatibility.<br><b>Packaging:</b> Components are securely vacuum-sealed or boxed to prevent moisture/rust and damage during transit.</p>
