I'm sure you've already seen this, but the B46-1738-H1 shows to be the front shock(s), and B46-1739-H2 shows to be a rear shock(s) per the Bilstein website. I'm still not sure what the B46-1738-H2 is. On THIS site it shows the B46-1738-H1 as being a front for the Rodeo and the B46-1738-H2 as being the front for the Trooper.
