stay away from the KYG. They'll be half the price the many times you replace them! The Bilsteins will last almost forever (I think some have a lifetime guarantee) MIne had KYG's when I got it. All rusted out, no performance, just miserable.

I put Bilstein comforts on the back, HD's upfront. (got the comforts cheap on ebay) they feel great. Invest the money in the better shocks. YOu wont regret it.
