What is the difference between the shocks end in -H0, -H1, -M0, -M1, or some other suffix?
The -[letter][number] suffix is a revision spec on that particular shock, and in the majority of cases makes no real difference in the shock themselves. Any small revision that is made by Bilstein along the way usually results in a different last digit, and this can be something as small as changing the manufacturer for a hardware kit on the shocks, where the main shock itself is not altered in any way. The exceptions to this are almost all with Off Road shocks for lifted trucks, where the different suffix options will appear on the same web page. It is safe to say that if you don’t see an obvious option on our website, there is no difference.
