I just ordered some of the Arnott SK-3354 struts. I believe they work on Suburbans, Yukons, Sierra's, and Silverados that have the Magnaride suspension. From what I understand, they plug right in and work as good or better than the factory struts. They're also made in the USA whereas the factory ones are made in Mexico. I'll follow up once I get one installed and see how it rides.
