Sale price$138.55


Champion diesel engine builders continue to push new records using a Fluidampr Performance Diesel damper. To exceed their requests to provide the industry’s leading damper, Fluidampr proudly offers new hardware kits and installation recommendations to further achieve long term performance and durability. These kits were developed and tested in conjunction with several leading competitors of the 2017 Ultimate Callout Challenge.

Updated – Fluidampr Cummins Drill Pin Kit

For high performance 5.9L and 6.7L Cummins® engines that exceed 3,500rpm, Fluidampr recommends the damper be pinned to the crankshaft.  Highly recommended for drag racing and sled pulling.  The current Fluidampr drill pin kit (p/n 300002) is upgraded from a roll pin to a stronger .0005” press fit steel dowel pin(s).  New to the kit is a smaller 7.7mm drill and reamer tool.  A drill fixture is included for accurate alignment with the damper’s pre-drilled pin hole(s).

Part number – 300002.  $54.55 MSRP.

New - High Strength Bolt Kits

For secure installation and peace-of-mind when further modifying your diesel engine, a new High Strength Bolt Kit is recommended.  Available for 5.9L / 6.7L Cummins up to 700 hp / 1,250 ft-lbs torque and 6.6L Duramax applications.  Each kit features heat treated, high strength extended length bolt(s) from ARP® and a .010” thick diamond impregnated friction washer.  Cummins 5.9L and 6.7L engines above 700 hp / 1,250 ft-lbs torque must use Fluidampr Cummins Full Power Kit (p/n 300008).


New – Fluidampr Cummins Full Power Kit

1989 and up 5.9L / 6.7L Cummins performance engine builds above 700 hp / 1,250 ft-lbs torque are recommended to use the new Fluidampr Cummins Full Power Kit.  Highly recommended for drag racing and sled pulling.  A ½” thick torque plate with textured finish mounts between the damper face and bolts to provide a wider and stronger clamping surface.  The torque plate incorporates a 5/8” hex head for barring the engine over.  New heat treated, high strength extended length ARP® bolts and a diamond impregnated friction washer are also included.  Use in conjunction with Fluidampr Cummins Drill Pin Kit (p/n 300002) for applications above 3,500rpm.

New – Fluidampr Friction Washers

Fluidampr recommends replacing the diamond impregnated friction washer in the Fluidampr Cummins Full Power Kit and the Fluidampr High Strength Bolt & Friction Washer Kit each time the damper is removed.  This practice ensures a secure mating surface between the damper and the crankshaft.  Available in single or three pack.


All new Fluidampr Performance Diesel Damper Installation Kits are available through leading automotive performance parts distributors and quality retailers.  For more information, call (716) 592-1000 or visit www.fluidampr.com.  Made in the USA.

Frequently Asked Questions

I already have a Fluidampr installed.  Should I update my mounting hardware?
If you currently have a Fluidampr installed and exceed 700hp / 1,250 ft-lbs torque, we recommend updating your mounting hardware.

I already have installed a Fluidampr Cummins Drill Pin Kit.  Can I update to the new dowel pin fitment?
No.  The new dowel pin is smaller and slight press fit.

How do I decide between the High Strength Bolt & Washer Kit or the Full Power Kit?
When in doubt choose the Full Power Kit.  Intended for high power competition engines, it will be more than sufficient for street performance applications.  It will also provide added peace-of-mind and one less item to upgrade if you pass the 700 hp / 1,250 ft-lbs torque threshold modifying your engine in the future.
