Will/can any of these companies re-valve for a radial with a new shock purchase?

Can you explain what you mean by the front of the car working? I have 5 inches of travel and the front is loose. I have 90/10 Caltrac shocks which replaced QA1 single adjustables. The Caltracs work better but now my problem appears to be in the rear unloading.The Rancho 9000 shocks have almost no compression damping only resistance on separation.

I have afco da on mine. Just went 1.35 60ft on 275/60/15 radials on motor. The afcos out of the box didn't work for me. I sent them to Mark Menser motorsports and he revalved them for me. He is a dealer for strange, afco, Penske, koni and a few more brands. Call him and he will set up a custom shock for your car. Mark (910)624-1119
I actually just got off the phone with AFCO. They would re-valve them brand new for little/no cost, but assured me at my power level that the eliminator valving would work ok. They said if it were a nitrous car instead of turbo, they would put the "Big Gun" valving in it, but that they thought I'd be ok as is.

He will call back, he can custom valve a set of strange shocks which I think would be cheaper then afcos . I have a bud that has gone. 4.60s in the eighth on the strange shocks done by mark.

This post could be a big part of your issue. Drag radials MUST dead hook to work. You can't black track them and get wheel speed up like you do a slick. A radial is hooked or not, end of story. So if you have a lot of front travel as well as it being loose, there is a possibility the car is just pounding the tire early, because the front has too much pitch rotation, too fast. Once the car tops out the suspension(which I am sure it does quickly) the car is DONE transferring any weight at that point and it simply unloads the rear suspension and spins the tire. No way a 9 sec car needs a 90/10 shock to transfer the weight
Those Rancho shocks are just a truck shock modified to go on these cars. They are in no way shape or form a properly valved "race" shock in my opinion. You MUST and I repeat MUST be able to control the rate and distance of front end rise, along with controlling the housing. Sloppy loose and pounding the tire early is NEVER going to work on a drag radial

The front end also needs a progressive stop for travel limit.
The factory travel limiters are designed this way. Using any form of travel limiter that stops the travel suddenly will transfer that sudden move to the back of the car, unloading it like Monte said.

Everything I am trying was recommended to me by people that have their set ups working. Caltrac recommends minimum of 5 inch travel. Front end as loose as possible no binding.
I have no way of adjusting the rebound on my current rear shocks but from every indication the car hooks then is turning the tire slightly through my 60ft.
Monty did you see the video I posted last week off my launch? Maybe you can tell from that what is going on?
Here's the link.

What are you using for a progressive stop?

I agree 100%! I was used to "slicks" set up and had the front of my truck as loose as could be. I had a chassis guy look my truck over, scale it, adjust the rear shocks (dbl Adj AFCO) and he told me my front end was too loose so he tightend it quite a bit. Hooks pretty well now!

Not sure why you think it is turning the tires for 60ft. Highly unlikely on drag radials. Like I said earlier, they are hooked or not and generally they slip at all, they spin hard.
Watching the video, the car looks way too loose in the front to me. It stretches the front end completely out real early and then sets the front end right back down, which will unload the rear
Monte
My 60ft times are way off and I have a racepak system. It shows the drive shaft rpm. The car is hooking at the hit of the throttle but then is spinning more than it should.
