What is the purpose of the "CS" holes on this crankshaft damper shell?

The "CS" or Crank Scraper holes are designed to help reduce windage and prevent oil from accumulating around the crankshaft. This can lead to improved engine efficiency and reduced parasitic drag.

What material is this crankshaft damper shell made from?

This crankshaft damper shell is made from lightweight aluminum. This material choice helps reduce rotational mass compared to heavier alternatives, potentially leading to a more responsive engine.

Does this part include the entire crankshaft damper assembly?

No, this listing is for the ATI Shell Assy (part number 917000CS), which is the main aluminum housing. The complete crankshaft damper assembly typically includes other components like an outer ring and inertia ring, which may need to be purchased separately or are part of a complete kit.

About this part

Product Details

This is the ATI Shell Assy, part number 917000CS. You're getting the main aluminum housing for the crankshaft damper, featuring a 7.074-inch diameter. It's designed with three "CS" (Crank Scraper) holes, which help reduce windage and oil accumulation around the crankshaft, and includes two rings for added tuning capability. This component is a key part of the overall harmonic damper assembly, crucial for managing torsional vibrations in your engine.

Crafted from lightweight aluminum, this shell helps reduce rotational mass compared to heavier steel or cast iron alternatives. This can lead to a more responsive engine feel, especially during acceleration and deceleration. The inclusion of the CS holes is a notable feature for those looking to optimize engine efficiency and reduce parasitic drag. The two-ring design offers flexibility for different tuning setups, allowing for precise balancing of the crankshaft's harmonics.
