Speedmaster UnderDrive Fluid Damper SFI 18. Harmonic Balancer (98-02 5.7L Camaro)Find parts that fit my vehicle

OverviewUsing only three parts--a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two--these SFI-approved Fluid dampers can control all crankshaft vibration, not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.SpecsBrand: SpeedmasterPart Number: PCE291.1073Part Type: Harmonic BalancerEngine Balance: InternalSFI Rating: SFI 18.1Degree Markings: NoOutside Diameter (in): 5.50 in.Harmonic Balancer Material: SteelHarmonic Balancer Construction: FluidHarmonic Balancer Finish: Black paintedMounting Hardware Included: NoQuantity: Sold individually.DescriptionThis damper is internal balanced; the term internal balanced damper"refers to the lack of any built in weight or offset in the casting. When identifying your existing damper, (balancer) you must look on the backside."This is not"visible"if the damper is"mounted on the engine."If your damper has no offset in the casting or weight, then you have an internal, (neutral)"style damper. If you do see the offset in the casting or a weight, you have what is classified as an external damper. They are perfectly balanced, hence the term neutral.
