I am surprised that Farrell's 5k springs aren't brought up more . I have run Columbus,Hasiley and Garmons 5k's and all had some compromise for Street use and running in general . Columbus installed there's Garmon installed his and another pump shop did the Hasiley install. Even with a ton of adjustment they were never something I liked for the street in an auto. I Installed the Farrell diesel 5k springs while the pump was on the truck and set them where he recommends and it was perfect. I would give him a call.
