Product Description
CUMMINS 3924435 OEM HARMONIC BALANCER (VIBRATION DAMPER) – 5.9L 12V (1994–1998)
The Cummins 3924435 OEM harmonic balancer (vibration damper) is the factory-tuned crankshaft damper for 1994–1998 Dodge Ram 2500/3500 trucks equipped with the 5.9L 12-valve Cummins. This genuine Cummins vibration damper restores proper torsional vibration control, protects main and rod bearings, and helps your 12V run smooth and quiet at stock power levels.
Unlike cheap aftermarket copies, this OE 3924435 damper uses a precisely engineered rubber isolator between the hub and inertia ring to cancel harmful harmonics through the entire RPM range. If your original balancer shows cracked rubber, visible wobble, or causes accessory belt issues, replacing it with this genuine Cummins unit is the safest way to protect your crankshaft and rotating assembly.
Pair this balancer with a fresh CUMMINS 3937111 FRONT CRANKSHAFT SEAL SERVICE KIT – 5.9L and new damper bolts like CUMMINS 3903857 OEM VIBRATION DAMPER / FLYWHEEL BOLT – 5.9L to lock in a leak-free, long-term front-end repair.

WHY REPLACE YOUR 3924435 HARMONIC BALANCER?
- Excessive engine shake: A failed damper can make your 12V feel rough, especially at idle and cruise RPM.
- Belt tracking issues: Wobble at the crank pulley often points to a balancer that’s separating at the rubber ring.
- Prevent bearing damage: Proper torsional control helps protect main and rod bearings, timing gears, and accessory drive.
- OEM quality: Genuine Cummins build, materials, and tuning for 5.9L 12V B-series engines.
INSTALLATION NOTES
- Inspect crank nose and keyway for wear or damage before install.
- Use new vibration damper bolts and torque to factory specifications.
- Ideal time to replace the front main seal with Cummins 3937111.
- After installation, verify balancer runout and belt tracking with engine idling.

FAQ
WILL THIS CUMMINS 3924435 BALANCER FIT MY 5.9L 12-VALVE?
Yes, this OEM damper is correct for most 1994–1998 Dodge/Ram 2500 and 3500 trucks equipped with the 5.9L 12-valve Cummins. Always verify against your engine serial number (ESN) and original part number before ordering.
WHEN SHOULD I REPLACE THE HARMONIC BALANCER?
Replace the balancer if you notice excessive engine vibration, serpentine belt misalignment, visible wobble at idle, cracked or bulging rubber in the damper, or any signs of contact with surrounding components. Many shops also replace it as preventative maintenance on high-mileage 12V trucks.
CAN I USE THIS DAMPER ON A HIGH-HP OR COMPETITION BUILD?
This is a stock-tuned OEM damper designed for factory power levels and moderate towing. For big injectors, high RPM, or competition use, a performance viscous or SFI-approved damper is recommended. Use this Cummins 3924435 primarily for stock or near-stock 5.9L 12V applications.
WHAT OTHER PARTS SHOULD I REPLACE WHEN DOING THIS JOB?
We strongly recommend new damper bolts like Cummins 3903857 and a fresh front crankshaft seal kit such as Cummins 3937111. Inspect the timing cover, gear housing, and keyway, and upgrade any worn components while access is easy.
