Well I finally got around to ordering them and putting them on..
20% stiffer all around...
5100 series. (yes the blue and yellwo ones-stock length)
Bought them from 4x4 parts..great service and advice-if I may say so..They recommded stcok height unless i was doing a three-inch lift in the real near future-I'm not so I stuck with what they suggested.

Well..the ride is just amazing...
I'm anticipating the 'bang' and 'boom' when I go over the cracks that are streets here are full of..and instead I'm getting a smoothe bounce when I go over them..

Let's just say..the OEm rear shocks are still compressed after we removed them...AND it's been over two hours...I think the swap and upgrade was OVER due...
anyhow...they're on and the X feels great....

For those who want to know:
Bils front numbers:F4-B46-1099-HO
Bils rear numbers: F4-B46-2126-HO

These are all 20% stiffer HD 5100 series.
