Most low cost valve springs are inferior to these in our opinion. Ratings are usually inaccurate, and quality is compromised.Power loss will result from springs that have taken set, became lazy as it may be called, much like the springs in a wornmattress.Low grade springs are notorious for loosing there vibrancy much sooner than a high quality spring. One more problem with such springs is that they are very prone tocontributing tovalve float at high rpm. If yoursprings are notquick and atthe properlb. rating then they not only have trouble closing the valve, they tend tocause the lifter to bounce at the peak point of the camlobe. Springs that are rated to low, are sure to cause power loss irrespective of wear. Standing height 2.22" We use .200 long valves with these springs.This setup is also used on most solid flat tappet sbc cams that are above .530 lift. Not to used with solid roller cams.

This set of springs have a retail value of, $175.00

This is full set dual springs with internal dampers in each. This is a total of three components in each spring.

Some sellers refer to the internal damper as a spring and it is not. The damper does provide a slight amount of spring action but it is not classified as a spring. This sale is for a true dual spring setup.

We have usedPioneer springs for many years and have yet to experience one failure. There are several low grade springs on the market that we have encountered, and found them to be very inaccurate onlb rating, not to mention there progressive rate is erratic. This may sound like sales hype, but take our word on this. We know of many sellers offering springs that not only have lb ratings that are incorrect, but the quality is poor overall. If you are not sure if these springs are correct for your application, feel free to give us a call at 423-722-5152 Having the incorrect springs for your cam will most certainly cause problems.

These springs are exactly what you need for a hydraulic rollercamshaft in the lift range of .440-.590 Not for use on any type of flat tappetcamshaft of any type.If youhave ahyd. flat tappet camshaft see our other listings for that spring kit.You should always use new locks and retainers with new springs. We offer many of the much needed hardware associated with valve springs. See our other listings.

The article in blue text below is copied from our cylinder head add, and pertains to the use of improper valve train hardware, please do read.

You can vary slightly on recommended spring ratings for your cam, and not have an issue. Give usa call if your not sure what you need.When a cam company says what spring rating they recommend, they are telling you what is most ideal, but just remember one thing, if they do tell you that you have to have that exact spring rating, they will also tell you that they just happen to carry that spring. As said, the rating they recommend is most ideal, but does not have to be exact. Read the article below on using the same springs for roller and non roller cams. This is not recommended and will cause problems.

We purchase these springs in bulk cases of 100ct., so no fancy package, but doe's it really matter.

IMPORTANT NOTE, MUST READ!

We have noticed several sellers offeringone size fits all valve springs for dual use of hydraulic flat tappet and hydraulic roller cams.

We are positively sure that theone size fits allis not theproper type hardware touse onyour heads. When using a hydr. roller cam, we not only use a dual spring and damper combo, but also use .200 long valves instead of the .100 long. The .100long valves are used on ourhydr. flat tappet setups.As many of you may know, a hydr. Roller cam is usually higher in lift and duration, requiring a longer valve, but all roller cams use a more aggressive spring setup regardless of lift, to keep the roller lifters planted on the cam lobe. They are very prone to wanting to bounce the roller lifteraway fromthe lobe due to the very different lobe design onthe cam, and theroller on thelifteralsotends to contribute to this.These sellers using a one sizefitsall setup, are trying to hit a happy medium, and most head builders we know of, are completely against it, as well as many head companies such as Dart, etc. If they have this setup somewhere in the middle, then it would be too much for the hydr. flat tappet cam, and create a wear issue in our strongopinion.Putting to much pressure on flat tappet cams is a sure way to kill the cam. It's just another way of increasing profit for the seller without regardfor thecustomers best interest as we see it.Werecommendthe correct spring for your setup and never is it the same on ahyd. flat tappet and a hyd. roller cam. Thespring requirements between a roller cam and flat tappet cam are dramatically different. Even the odd ball solidflat tappet cam, has its own uniquesetup depending on what lift it is. The one size fitsall hardware claims to also work on these cams.We know of several sellers offeringthis insanesetup to suspecting buyers, and it’s not the proper way to set up a set of heads, in our very strong opinion!

We have to charge a slightly higher price for a set of heads using a hydr. roller cam and we can promise you, it's a must that the hardware be correct for this type cam.Call up any cam manufacture, and tell them you want to use a one size fit's all setup on their hydr. flat tappet cam orhydr. roller cam and they will tell you this is not possible,and depending on thespring pressure,it can't serve both properly.Valve float, on the roller setup, or extreme wear for the flat tappet cam, depends onwhat cam this crazysetup is closer to. We would not even consider this type hardware, and believe me the simplicity of it is appealing.

Take heed to the warning above, and rest assured we will never guide you in the wrong direction when it comes to valve springs. Some cam companies may isolate the spring recommendation a bit closer, and tell you that you need a certain spring rating for use with acertain cam, and you can vary lb. rate slightly lower or higher without any ill effects, but never will they tell you to use the same springs you used on a non-roller cam as you would with any roller cam, or visa-versa.

Note from our company president, Skip white

We have seen the low cost springs on the market, at what appears to be very good prices. My advise isto avoid them like the plague. Not only is the quality questionable, We have foundthe lb rating to be grossly inaccurate from what they claim to be. We have a spring tester in our machine shop and this not your micky mouse tester many garages use, but ours has a cost of well over $1,500.00 We build heads costing over $10,000.00 per pair and need this type of spring tester. What we have found besides the lb rating issue is that these inferior low cost springs have very poor progressive rate characteristicsto them. Their appearance is also the worst we have ever seen. For those of you that don't know much about springs, I can tell you one thing for sure, valve springs have several very critical factors in their design, with little room for error,orpower loss orfailurewill result. One of the factors that is to be addressed is how long the spring can operate before it takes, "set" This in layman terms means that all springs become lazy in howquick and firmlythey rebound. Springs that take set to soon, and to much will cause an engine to run poorly. Even the best springs on the market are prone to this, but to much lesser extent, and will run much longer before it becomes an issue.As many of you know we do sell many off-shore products, but when it comes to valve springs, we will most likely never offer anoff-shore spring set. The ones I have seen are absolutly terrible. We are at master warehouse distributor level with Pioneer, and due to the massive amount of hardware we purchase from them, we are able to sell thesesprings at a very good price.You will be much better off paying the few extra dollarsvs. than purchasing the low endsprings regardless of how low the price may be.We know of a very large valve hardware supplier that purchasesmany products from off-shore companies, but like us, they never buy offshore valve springs, as a matter of fact it is Pioneer springs that they carry.A spring has very dynamic characteristics to it, so trying to copy a valve spring can turn out all wrong for someoff-shoremanuafactors if they lack the true engineering skills. A valve spring is a moving part, and moving at a very high rate of speed with extreme levels of pressure against it. Harmonics are involved, high temperatures, wear points must be addressed, etc. There is littleroom for error. The spring must operate for a long time, and precisely. The metal used is very important as is the heat treating process, not to mention the overall design, and size must be correct. Just to give you an example of how critical a simple looking spring can be, most high level race engines use springs costing over $500.00 per set. That right there tells you that springs are very complex. By the way those high level race cars using those expensive springs, will usually replace them every season or sooner, as the slightpower loss becomes evident.Now think about all of this before you go buy a set of $29.00 springs for your street-rod. If getting a set of low grade springs is not bad enough, having the incorrect spring is worse. We will never give you the incorrect spring for your cam. You may also see low cost springs on the market that are in the 1.25" range witha correct spring rating, the problem with these is they tend to wear out at a very fast rate, due to their small physical size, but one exception to this rule are some of the high grade bee-hive springs on the market. Those particular springs are usually very high quality, and the size rule does not apply to them. Some of the ultra low grade springs we seen were not small diameter, they were actually larger than ours, around 1.50" but the wire diameter was much smaller, therefore making it's larger diameter irrelevant to it's durability. When springs get to the 1.5" diameter size, they tend to cause issues with roller rocker clearance, and the need to cut the base area largeron many oem style heads. Our solid roller springs are of this larger diameter, and are made from very thick wire, but our stainless roller rockers clear them comfortably.

final thought, I feel the same way about off-shore lifters also, avoid them like the plague as well.

Enough said.
