Hotchkis or Bilstein shocks

Stock 340 TB would be .870. Big block A body TB were .890. Bilstien RCD shocks are valved for performance use from stock up to about 1.00 TBs. If your going up in TB size over that I suggest the Hotchkis/Fox, which from my research, are valved for TBs in the 1.06 area. They have an adjustable version out now also. I'll be running the non adjustable Hot/Fox on my Duster with either 1.06 or 1.12 TB, decision not made yet. If your going to stay with a more stock setup there is nothing wrong with a lower priced replacement shock like the Monroe's mentioned above. The KYBs are valved harsh but a lot of people run them.
