3.9L Cummins 4BT and 4BTA High-Performance Diesel Harmonic Balancer
The Fluidampr 3.9L torsional vibration damper applications:
The Four-Cylinder 3.9L Cummins 4BT series diesel engines are in high demand for the enthusiast who is doing a motor swap. The Cummins 3.9L 4BT Cummins inline-four diesel engines were manufactured from 1984 to 1998. These eight-valve engines produce 105 HPand 265 lb-ft of torque from their compact size of 30.6 inches long, 24.6 inches wide, and 37.7 inches high.
The Cummins 4BTA was introduced in 1998 and was produced until the end of 2001. This newer model four-cylinder diesel engine received an upgraded valve train with a 16-valve configuration. This new valvetrain allowed for increased performance levels with a horsepower bump to 170 and a more impressive 420lb-ft of torque. Depending on the application, the power figures vary. This is what makes it such a popular candidate for engine swaps. Weighing in at nearly 800 pounds, the durable inline four-cylinder engine is the little brother of the 5.9L Cummins 12-valve Cummins diesel engine.
The High-Performance Cummins 3.9L Viscous Harmonic Fluid Damper benefits:
KLM Performance strongly recommends the installation of this damper on your Cummins 3.9L Transplant vehicle in order to reduce the high level of vibrations produced by this motor.
KLM strongly recommends the replacement of your Damper bolts when replacing your damper, since these are torque-sensitive bolts, once removed, they should not be reused. That is why we now offer this damper with the ARP 147-2502 bolt kit.

Fluidampr 3.9L Cummins Performance Diesel Viscous Damper Specifications:
Dynamometer tests have shown consistent increases in horsepower and torque in the Cummins 3.9L with a Fluidampr viscous vibration damper installation. The OEM Stock elastomeric dampers have a short life span and do not control torsional vibrations at all RPMs like this viscous harmonic balancer.
