description

This 455-8404 is disc rubber torsional damper assembly. The vulcanized rubber dissipates torsional vibration energy and reduces fatigue stress on crankshaft, bearings and timing gears. Each unit passes crack inspection, dynamic balance and rubber durability test. It is a key rotating protection part for C9.3 engine overhaul.

FAQ 

Q1：Can 455-8404 interchange with 352-4522 damper?
A：No. Fitment, bolt pattern and tuned frequency are different.
Q2：Is this a Reman part?
A：No. It is brand new OEM assembly with new hub, rubber and inertia ring.
Q3：What symptoms will appear when this damper fails?
A：Engine shake, timing gear noise, accelerated crank nose and bearing wear.
