Unfortunately we are unable to lookup part #'s for your Chevrolet C5500, however, I do believe all of the 8.1L's use these same knock sensors. You would be able to confirm by contact a GM dealer and having them verify the part #. ( Support )
Have a code PO332 and PO327 on a 2005 Admiral Workhorse with an 8.1L. Do you have a diagram that shows where these sensors are? ( Kyle Watson, 05/14/2020 )

Are these the correct sensors for my vin ? Does a certified mechanic required to install? ( Kenny Bracken, 11/01/2019 )

I just got CODE PO332 on my 2007 Workhorse W22 (Engine Light) - Would this be the issue? Also are there more than one (1)? Should I also replace the pigtail wiring to both? It appears this is the correct part for my chassis. ( Wilfred Bush, 06/26/2019 )
This is the correct part but we are emailing you the diagnostic trouble shooting steps for that code to aid in diagnosing the issue. ( Support )
Do you have the plug/wire for this sensor? ( Roy Chapman, 12/03/2017 )

I have a 2003 Winnebago Brave, Workhorse chassis, and 8.1 Vortec. Is this knock sensor OEM? It appears it may be based on number. ( Jim Muir, 06/05/2016 )

Jim,

Yes this is the OEM knock sensor for your 8.1L.

( Support )

Hi Do you need to change both sensors if only one is giving the error reading Cheers Peter

( Peter, 02/04/2016 )

Peter,

It would not be necessary but it wouldn't be a bad idea to do so.
