I ordered a set of Bilsteins, and I wanted to get the 20%'s. But on the invoice on the computer it says BILB46-1099-H1. Isn't H1 the 4X2 (10%) and H2 the 4X4 (20%)?

One other quick question, they already shipped it out, and its really going to be a pain in the ass to ship it back for the right one (if I'm right bout the part number). So would the H1 work on a 4x4 and would there be a major difference in performance/absorbtion?
I'd search but I'm at work and I don't have time, but I'd also like to deal with them this afternoon before the weekend.

Thanks alot.
