I have been runnig pro shocks but im thinking about going to a bilstein because they seem to have a better selection of valving. Ive never ran a gas charged shock before. any opinions on this suject guys?
I really like the pro's too I just cant seem to make up my mind....lol

I ran the Pro Shocks before I switched to the Bilstein and have been very satisfied.

I had about 40 pro\afcos and sold them all over last winter for 5-15 bucks each and went to bilsteins...

the first race track I went to with bilst was a track I previously ran which develops a car sized hole in 3. with pro afcos that hole was bone jarring to hit, very unsettling and felt like it launched my car.

the bilsteins made me come in and ask a fellow driver if the hole I could see mods going thru was there during my heat race...

the bilsteins are way better in my opinion. Ive got about 20 bilsteins allready!!

I ran afco/pro on my old old car, then I went to bilstein, and a few carrera ones. I try run the bilsteins as much as possible. here is why.
1) valving selection
-with a bilstein you can get an almost unlimited choice of shocks, afco will make you a custom vavled shock for like 145 i think it is. BUt I have seen some of those afcos, some come in the box and are supposed to be an easy up, but are really about an 88 valve. Other times just dynoing them they are not what they claim they are on the side.
2) That above reason leads me into my next point about the shocks would be the consitant shocks that bilstein gives you. The afco, and pro(better than afco) your not 100% sure what your getting I mean it could be a 94 or a 95 or a 96 but say 95 on it. BUt a bilstein on average will have a much higher consistancy meaning you get a 50 valve it dynos 50 most the time.
3)tube design, the pro and afco are twin tube, the bilstein is mono. Meaning that the bilsteins run much much cooler, so not as prone to overheating and shocks dropping off.

On rough tracks nothing compairs to a good monotube like a bilstein. That would be why leaf has liked them. ON a slick track twin tube was the way to go in the past, lower shock pressure, but newer bilstein shocks are above most mono tech. So they work good on slick, plus yet again the twin tubers are prone to holding heat, and on a slick track and alot of laps....

I would go bilsteinds if you have themoney, 20 maybe overkill but if you got the money never hurts.

Thanks for the info. zeroracing. Alot of the tracks around here can get pretty slick and thats the one thing thats been keeping me from bilstein's but after listing to you and I do like the valving they have to choose from so I think I will give them a try. Ive been beating these shocks in my head for a while now....lol
thanks for all the comintts fellas!

I have seen afcos go bad really bad. Almost new, A friend of mine had a set and he sent them back to afco a couple of times for dyno they kept saying they were fine and they would send him some generic dyno sheets for that shock. he finnally sent them to a private dyno company and the shocks were way off. Afco finally gave him a new set of shocks but he switched to konis and had much better luck. This was a few years ago mabey they have gotten better. I run pros and had okay luck with them but I would like to try bilstien once I get the money to switch.

I've got a deal going on Afco stuff right now, so I'll be running them next year. If I wasn't running Afco's, it would be Bilstiens. We've ran Bilstiens on our USMTS Car's for years now. Yes, they do cost a little more, yes, they do cost a little more to break but the cost difference is worth it. If you can give a little performance up, and want to have a wide variety of shocks, you can pick up the Pro WB Series pretty cheap. I ran Pro's this year and had no problems. With only running 12-15 lap mains, the shock's never had much of a chance to get real warm. On good, smooth dry nights the shocks would barely get any heat in them.

A Hole in a race track is going to feel the same with the same rate shock on no matter what the brand. This isn't a street car that should ride the road smooth.

I also switched to pro-shocks call Chad Fox at pro he can fix you up but you need to get the shocks dyno i run two 76 shocks across the front and 94s acoss the the rear .I also switch two shocks for the slick 95-3 for the lr and a 75 for the rf.On a slick smooth track these work.CALL Chad he can help you out.

If you have some funds, I would say get together with a good bilstien shock guy like HCI shockdyno i think it is on 4m.net If I had the cash to go shock wild I would get all mine from him. He did some bilstiens for a local late model guy and the guy said it made a night and day difference over his afco's which were 2 way adjustables, that were sent back and forth like 3-4 times and were supposed to be super trick. The car was atouring series car with a very experienced driver, so if he claims the bilsteins to be that much better then that says alot of bilstein and for the guy Herb i think at HCI shockdyno.

Also a side note I would choose my shocks in this order.
1)bilstien
2)qa1, would like to try some sometime with a whole set up for changing vavles(I dont think they would compaire to a bilstein on rough, but on slick if kept cool might show some progress)
3)Pro or carrera, probably pro I had a few on an old car and they were not bad, but destroy 9010's from pro with ease(I think I overextended them once or twice or smashed them down which is my own fault for them failing).
4)afco blue expensive ones
5)cheaper afcos

Above when I mention the qa1 kept cool, I mean twin tubes hold more heat and build it faster, so you must keep it form over heating worse than a bilstein. And with the low pressure of a qa1 if kept cool they would be pretty good. Bilsteins only downfall in my book is the gas pressure(great for rough heavy) but a high gas pressure gives up some on the slick. But Also stated above with newer tech and more info on them the multiple vavlings of the bilstein will make up for the little disadvantage of the higher pressure. It would be really cool if bilstein would come out with a slick track set with lower gas pressures, so the shock would not push you so hard when putting it on and react a little better over slick.
With the nicer bilsteins you can adjsut your own valings and pressure(this one some) but they have a scharder valve so not legal for most mods.

Any shock you go with(brand) try to get a knowledgeable person to help you with them. Try to work with them to get the most out of your car. Dont go overboard and spend the teams budget on everyshock combo you can imagine(know a team that has EVERY combo you can come up with). Start with the standard valves get the car set up pretty good then start with the split. Shocks are not your saving grace for a terrible car, but can make a good car great.

When you first get your shocks take them out of the box, and put them thru a few cycles up and down(seen a new custom vavle afco fail this test it went one way...) This can alert you to any major problems before the shock goes on. Also inspect them over good, if you can get them dyno'd then do(some times a late model or sprinter or asphalt local mgiht have a dyno, use it if its cheap for you too if they want to charge alot then no). Then put them on the car, be careful not to bind them/bottom them out/ over extend them/ or overheat them. On the overheating you might try to take a few temps on them every so often, and maybe call the manufactor and see if they have a recomendation like if you say it comes off the track and i get to shoot it with the temp gauge abotu 2 min after but it reads xxx then they might be able to tell you if your overheating it or not. Steel does loose the temp from the track to the trailer but not that great of loss. Also as far as dynoing I have heard of alot of guys using heating blankets to get the shocks at least warm before they start.

Hci is in mississippi Herb just recently fixed me 4-shocks i have only run them once but i will say this these shocks are not like off the shelf bilstein. After trying herb shocks i will never have a off the shelf bilstein again. Herbs shocks are a differt feel i am used the the pro's i post earlier.If you go pro's get them dynoed.Next year i am starting out with hci shocks there is a feel there is very differt what i found out i could really get in on entry good.Hang on this guy know his shock .
