Features: - Steel Material - Black Zinc Chromate Finish - Has Laser-Etched Timing Markings - Helps Protect Against Harmful Engine Harmonics - Prevents Oil Pump and Other Components From Breaking High-Quality and Absorbing Unnecessary Vibrations Unlike unbalanced underdrive pulleys, which offer no protection to high-performance engines, the SLD Super Damper provides balanced dampening of torsional crankshaft vibrations at all RPM. The SLD Super Damper comes with laser-etched timing marks and is a direct replacement for the stock OEM unit. The Super Damper is especially needed in high performance and modified trucks to help protect against harmful engine harmonics and features a six groove serpentine belt drive on the outer shell to utilize the factory serpentine belt set-up. All SLD Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition use. Reduce Tension and Strain on Your Crankshaft The SLD super damper is the upgraded component you will need to ensure your vehicle's engine and crankshaft are well protected from breaking or causing too much tension that can damage your vehicle. Not upgrading your damper will cause oil pump failure or cracking, your flywheel could break and more issues with other components due to the intense tension. With increased horsepower for racing events, its best to upgrade the this super damper from your stock model to prevent causing damage during racing events. FitmentGM 2500/3500 6.6L V8
