I've seen a Rancho ID on this forum from time to time so hopefully he will see thsi and chim in.

I bought as set of Rancho Steering Stabilizers with a 9XXXX series model number. they came with RS5000 series shocks .

I also learned there are 7000 series stabilizers available.

Also wondering why I could not use 9000 series shocks in my stabilizer kit.

truck is stock 2008 f-350 DRW

so basically, I plan to swap out all the shocks with 9000 series shocks (or better)

a. model number for the front
b. model number for the back
c. I'm thinking that a properly sized 9000 strut can be used in the steering stabilizer...which model has the same travel as the RS5000 struct the stabilizer kit came with?

also, who should I buy from to get the warranty?
