Product Advantages

1. Non-AFM camshaft + solid lifters permanently disable factory AFM/DOD cylinder deactivation, fixing common issues: loud lifter tick, collapsed lifters, misfire codes, rough idle and excessive oil consumption, delivering consistent full-cylinder power.
2. OEM matching cam specs maintain stock drivability without sacrificing low-end torque for daily driving and towing.
3. MLS reinforced steel head gaskets withstand high heat and pressure to block coolant, oil and vacuum cross-leaks.
4. Timing cover gasket eliminates persistent front timing cover oil seepage after overhaul.
5. High-tensile torque-spec head bolts and harmonic balancer bolt ensure uniform clamping load to prevent gasket blowout and front seal failure.
6. All valvetrain and sealing components use wear-resistant alloy and heat-resistant composite materials, one-stop combo cuts parts sourcing time for repair shops and DIY LS rebuilders.

Purchase Notes
