Ok, I reread what SLR sent you and it doesn't add up. The H1 says 10% stiffer and bilstien says its for the 4x2. So it the shock for the 4x4 (bilstien says H2) MUST be stiffer. I know for sure the H0 will be stiffer than both because its for the winch/arb owners.
So according to Bilstien, lowest to highest stiffness would be H1, then H2, and stiffest H0.
But SLR seems to be saying, H2, then H1, and stiffest H0.
I don't know anymore....
Yeah, I think the bilstien suggested one is right. This is from the group buys forum.
Front:
B46-1099-H1 4X2
B46-1099-H2 4X4 (10%)
B46-1099-H0 4X4 (20%) valved for extra weight of winch
