Another shock question

[moving violation]

I'm currently running stock mount afco shocks. Thinking about switching over to bilsteins but I don't see any valving that I like in there front shocks for the linear shocks. This is for a factory stock that runs on Asphalt. There are plenty of shock builders and shock packages for dirt can anybody recommend a shock builder that has any asphalt experience?

I was thinking of running the AK 4040 on LF, 3060 RF, 3030's on rear. My only concern is the digressive valving in the front shocks especially the RF might reach the blow off point of the shock that's why I want to try linears on the front and digressive's would be fine on the back. I am just curious to see if anybody has any shock builders with asphalt experience. Thanks for the response.

You can try WAHL Traction here in Vegas. They do a lot for the bullring stuff out here.
I haven't had to use him yet but most the dirt guys I run with have and like him.
