That shock is on my silver Duster, Jims HemiDemon, etc....I dropped the spring weight 20% when I went to the 12" coil over/spring vs the 10"......made for a smoother ride.
I know you have the monster motor but what spring weight did you end up with I now have the 400 on a 10" which is to much probably more like 300 to 350 do you know your front weight a friend is bringing over his 4 corner scales to weigh my car
