SPRINGVILLE, NY [June 30, 2026] – Fluidampr announces the release of Performance Damper p/n 720361 for naturally aspirated Dodge / Chrysler / Jeep Gen III HEMI-powered cars and SUVs. Designed for high-performance street and racing applications, the damper combines broad-RPM-range crankshaft torsional vibration control with a removable 6-rib accessory drive pulley featuring a dry sump mandrel mounting provision, plus future crank trigger and accessory drive flexibility. Developed using OEM-level torsional vibration analysis methodology through parent division Vibratech TVD, testing conducted with Scoggin Dickey Parts Center Raceshop demonstrated an average reduction in crankshaft torsional vibration of 8% over stock elastomer damper tested, 13% over clutch-style damper tested, and 4% over O-ring style damper tested.
The 7-1/4” steel housing viscous damper is designed for durability in high-horsepower street and racing applications and features a removable 6-3/8” diameter, 6-rib aluminum accessory drive pulley. The pulley incorporates three pre-drilled 3/8-16 UNC 28 bolt holes on a 3.20” bolt circle for common-sized dry sump oil system mandrel mounting.
The damper comes in a corrosion-resistant, RoHS compliant black zinc finish along with laser engraved SFI 18.1 certification markings, while the pulley is black anodized, both for timeless appearance in street and racing environments.
Unlike tuned elastomer dampers optimized for narrow frequency ranges, Fluidampr’s viscous damping design provides broad RPM range torsional vibration control without tuning or maintenance.
New Fluidampr performance dampers are developed and validated using OEM-level torsional vibration analysis methodology through parent division Vibratech TVD. Testing for p/n 720361 was held in conjunction with Scoggin Dickey Parts Center Raceshop. During engine dyno crankshaft torsional vibration analysis, with sensors on both ends of the crankshaft, the Fluidampr performance damper reduced vibration across the RPM range by an average of:
- 8% over stock elastomer damper tested.
- 13% over clutch style damper tested.
- 4% over o-ring style damper tested.
“Seeing firsthand the level of analysis involved in measuring crankshaft harmonics, damper performance, and the specialized equipment required for this type of testing was extremely impressive,” Gordon Paden, Scoggin Dickey Parts Center R&D Specialist, remarked. “Testing of this caliber is critical for improving durability, reliability, and overall engine performance, which is exactly what we are all about at Scoggin Dickey Parts Center.”
From engine dyno lab testing to the track, Fluidampr partnered with Chris Baily, Gen III HEMI drag racing record setter and owner of Baily’s Hyperformance. Baily helped initiate Fluidampr’s viscous damper development after experiencing RPM signal fluctuation and compromised tuning accuracy from needing to relocate the crank trigger on his own build. “As someone who is constantly pushing the limits of the Gen III HEMI platform, we’re always looking for products that solve real-world problems while creating new opportunities for racers and builders,” Baily remarks.
Beyond the common dry sump mandrel mounting capability, Baily added, “Fluidampr listened to the needs of the community and delivered. It’s engineered with future growth and adaptability in mind that help racers and performance enthusiasts take their builds to the next level. The ability to easily configure different overdrive and underdrive ratios gives builders more options to tailor their combination, while the crank trigger capability opens the door for advanced ECU strategies and standalone engine management solutions.”
