KYB Gas-a-just: front p/n KG4515 and rear p/n KG5507 available at Summit for $29.95 each. Or as a set of 4 from PST for $130... Not at all saying that the above shocks won't work well or last, but in my experience with my LeSabre, Gabriel, Monroe, or other locally available HD gas charged shocks worked very well for about a year, then lost their "edge". I've had KYB's on the front now going on 4 years, and it's still very much under control. I'm convinced they're worth the little extra, just 'cause I haven't had to touch them.
I have run a set of KYB's for 12 years on one of my cars and they still feel great. They are a little pricey, but I think their worth it. I tried Bilsteins last year on my truck, but never liked the feel of them on the hwy as well as KYB's.
