Fluidampr Harmonic Balancer
The best harmonic balancer for your 6.2L or 6.5L diesel! Performs better across all RPM ranges and smooths out engine operation. These are so popular on this platform since GM omitted fine rotating assembly balancing to save $$ per unit on millions of engines. The Fluidampr is able to absorb some of that imbalance and protect your crankshaft against harsh harmonics. We always suggest balancing when re-building these motors for longevity but always run the Fluidampr to protect against the inherent harmonics that a diesel engine creates with high compression.
Replace it once and never worry about deteriorating stock rubber dampers again! This is 100% maintenance-free when coupled with a billet crankshaft pulley!
Please select the correct variant for your application. DB2 (mechanical) pump engines require the 6.2L version with spacer ring because they don't have the wider crankshaft reluctor wheel like DS4 (electronic) pump engines. The 6.2L variant can also used with or without the included spacer ring if you want it to be flexible in the future.
