Which ones do you prefer?

I own some AFCO coils, never had a Hypercoil. Do you preferr one over the other?

I am going to clean out all my old springs, except a few that i bought new and start over, and i just cant seem to make up my mind what brand to go with.

I asked this question a while back and most all of the responses I got were the Afcoils. I can tell you one thing, stay away from the Speedway Tru-Coils. They are JUNK!

Ill tell ya I hate the afco pregressive pull bar springs, I swear by the hyperco pregressive pullbar springs. So we run the Hyperco pullbar spring and this year I thought I would follow suit and get all hyperco springs.
Well 4 weeks in to the year we were losing forward bite real bad and we had a rr spring go bad it rated out fine but it lost 1/4 of free height, and our front spring rated bad, Not bad but not what they were suppose to be, our 650 rated at 600 and our 750 rated at 650, WOW!!!!
we put afco spring in and it is a whole new car, Now were trying to free it up.
So to make a long story short, I recommend afco for the 4 corners of your car but the hyperco for the pullbar.

what problem did you have with the AFCO progressive spring??? I ask this b/c thats what I run is the Afco progressive, I'd like to know what you found wrong. I've been running mine for 3 years now and so far I haven't had a problem that I can tell, but there may be an underlying problem, so whats wrong with em'???

I just read your other post Krom, where your talking about your RF spring. You said it was a Speedway!!!! Thats MOST likely your problem. I have had a few of the Speedway springs collapse on me. Most recently my LR spring collapsed it was a 200lbs. I definately DO NOT recommend those springs for that very reason. That 200lbs spring probably didn't have 10 races on it. I also had a 225 collapse on me last year. So replacing that RF spring of yours with a good quality AFCO spring is surely going to help your problems!

I have used the tru coils in the past but now use afco. Who makes the tru coils for Speeddway? Has anyone used the Eibach Springs or the coils Landrum sells along with the coils South West Speed sells?

when I ran stock cars, alot of the guys used Southwest Speed's Black Magic springs but I've never ran them.

I am also curious about Eibach springs. I know they made the progressive spring for Harris' new pullbar.(by the way if anyone knows...can you buy JUST the spring??) I also know they make ALOT of springs for street cars, so they must not be too bad.

We got a bunch of the Speedway springs with a deal we bought out a year or so ago. I will be getting rid of em. I think your right, i believe that RF is the issue on our handling.

Thanks Don on the heads up about with the Hypercoils, may be its an isolated issue but i dont want to give it a chance to isolate me.

AFCO coils for me.

eibachs are real good springs but they lose their rate after 10-15 races.

I guess we have been lucky, we have ran the speedway springs for years have four on the car right now and it handles fine. If the handle goes away I will check the springs thanks for the info.

How can that be a good spring if it loses rate after 10-15 nights?

If you dyno and rate you coil springs like I do you will fine that Afco springs are of poor quality. They are inconsistant and range +/- 20% rate change. I have found 1 out of 50 brand new Afco springs rate what they are marked. Eibach and hyper coils seem to be the best for quality and reliability. Between the two I found maybe 1 out of 50 tested to be about 2% in stamped rate. and testing used springs never had an Afco rate even close to stamped rate. We just had a customers car in the shop could not get any cross %. Changed out his Afcos to Eibach (used) and wow that car reacted to every change we made. With the afcos we cranked and adjusted and no change just in chasis hieght. Customer clim springs were new this season. At our shop we recomend to change out coil springs every year, Just like torsion bars every 6 to 8 races.

what makes it tough is without a dyno, you have to find out the hard way for the most part. I have little or no trouble with the speedway springs, or the afco springs but after reading some of the posts here it reallly makes you start to wonder.
There are so many brands now, such as Suspension Spring Specialist, and SW Speed Black Magic
What it comes down to in many cases is what you can get when you need it, almost everyone sells AFCO.

Eibach and Hypercoils are not off the shelf ready at a lot of suppliers.

The trouble with the guarantee is that you have no way to dyno the spring to know if it is bad to send it back.

How many of you have ever tried sending one back and what was the result ?

I may be wrong here, but with Afco's guarantee is the rate guaranteed? I was thinking it was only the springs free height?? I may be wrong........

I definately ain't the best driver on here, or the fastest - but some of y'all seem to be missing something.... I pay more for shocks then springs and after dynoing they are way further off then springs change usually.
What I mean is for what they cost and for what we DO to them (the most highly stressed metal in any racecar is the springs) I don't expect them to last forever....
Not being a smart-guy, just saying think about what a RF spring goes through on a really bad track ? How long can any of them last ?

I agree they do go through alot of work, but my concern is that on a tight budget like I am and many other racers are, we always are looking for ways to get MORE than our moneys worth.(doesn't happen much or enough LOL) Normally springs cost around $50 each, thats a good price, but in the long run i would be better off to spend $100 a spring for ones that would last longer and perform better. So I wouldn't mind spending a little more for a better quality spring, same as with a shock.

So basically what I'm saying is Yes you are definately right. For what we put them through they aren't going to last too very long, so searching and finding the best spring brand for yourself is critical in my opinion.

Well if they only last a year thats fine with me, but if i buy a 950lb spring it better be a 950lb rate, or am gonna go find another spring company.

Where do they sell Landrum coils? I've been trying to find them with no luck.

Anyone that sells Landrum can get them for you if tell them what you want, or if you have the part number which you can get off Landrums website.

The issue you will most likely run into is that a lot of places dont stock anything but the landrum leaf springs, so they will have to order them for you.

This is what I mentioned earlier, if I want anything other than AFCO in my area I cannot get it very quicly.

2-3 days I get almost any brand, but AFCO I can get in one day. I have a couple of Eibach springs and I like them so far.

The other problem with AFCO is the way they ingrave the rate on the springs, when they get old you cannot make out the numbers very well. The Speedway Springs have it stamped into the spring, which is nice.

I rate every spring I put under my car with an accurate digital rater. When I started this last year the results were shocking. I rated AFCO, Hyperco, Eibach, Suspension Specialist, and a couple of no names I had laying around. Many were new or nearly new. They are all over the board. I used AFCO's rating method. Most AFCO are about 7 to 10% under there rating. Hyperco are a little closer, but not much. My Eibachs were used, but were consistently 15 to 20% under. Maybe they use a different method. For some reason, rear springs tended to be closer to there rated #'s, usually +-5%. I don't think any spring companies guarantee the rate, only the free height. Just because their off their rate doesn't mean they're junk. Once they start to lose their height or lose rate from what they started as, then they're junk.
