The FLUIDAMPR GM LS3/L99 7-3/4 Damper with SFI certification is a premium harmonic balancer engineered for General Motors LS-series engine platforms. This internally-balanced damper features a 7.750-inch outer diameter and steel construction with black zinc finish, designed to absorb crankshaft harmonics and extend engine durability under high-load conditions. SFI certification ensures compliance with sanctioning body requirements for racing and performance applications, making this damper the choice for serious engine builders and performance enthusiasts.
The internal balance design matches factory LS3 and L99 engine specifications, eliminating the need for external counterweights and simplifying installation. Steel construction with black zinc plating delivers corrosion resistance and structural integrity under sustained RPM cycles. The precision-engineered hub and elastomer compound work together to isolate damaging vibrations at critical frequencies, protecting connecting rods, crankshaft journals, and main bearings from premature wear. This balancer is suitable for naturally aspirated, turbocharged, and supercharged LS applications where OEM-spec harmonics management is non-negotiable.
Engine builders, performance shops, and LS platform enthusiasts rely on this damper for track builds, off-road power units, and high-output street engines. Whether for weekend track duty or dedicated competition service, the FLUIDAMPR damper delivers measurable harmonic control that translates to improved reliability and extended bearing life. The SFI certification also satisfies technical inspection requirements at sanctioned racing events, making this an essential component for any serious LS build.
FLUIDAMPR is the OEM damper supplier for multiple manufacturers and has built a reputation for precision harmonic engineering. This LS3/L99 damper represents the same proven technology trusted in factory production environments, now available for aftermarket platform builds. Part number 760121 ensures exact fitment and performance matching across all LS3 and L99 variants.
