The new Ferrea Valve Springs are processed with premium-grade alloy and feature special thermal treatment. Ferrea's advanced spring design and material specs have uniform load and stress distribution even in the most extreme racing conditions. Great for high revving applications. These valvesprings and retainers will reliably allow your engine to rev high without the worry of part failure, valve float, or coil bind. Aftermarket valvesprings are made out of superior metal alloy's and optimized spring rates to make sure your valvetrain can keep up with your cams at high RPM. Whether you are rebuilding your engine, or building an all out race engine, replacing your valvetrain with Ferrea components will allow you to rev higher, and go more aggressive on your cams.


Ferrea is the top of the line when it comes to valves springs and retainers. If you google "Ferrea" you would be hard pressed to find anyone say anything bad about them. They are not the cheapest on the market, but if you want the best, Ferrea is the way to go.



There are 3 Major Issues with stock valvetrain, that can be prevented by using Ferrea Components.

- BIND - They can "bind" and get stuck, losing their ability to open and close the valve. This is an easily diagnosable failure. Depending on how it binds, it could cause failure to other engine parts.

- BREAK - They can "break" into pieces dropping the valve into the combustion chamber and consequently ruining your bottom end.

- FLOAT - "Valve Float" is a hard to diagnose condition where the valve spring rate is not high enough to fully extend the spring and close the valve after a complete rotation of the cam before the cam comes back around again. So what ends up happening is that when the cam is spinning fast (high rpm) the valve never closes, and combustion leaks out of the engine, and the engine loses power.



    Kit Contains :

    Single Spring S10157 Qty 16
    Titanium Retainer E11139 Qty 8

    Seat Locator SL1142 Qty 16


    Our springs are heat-treated and stress relieved, which dramatically increases the spring’s life. Our valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today’s aggressive valvetrain combinations.

    We currently offer four different types of retainers to choose from: Titanium, Lightweight Tool Steel, Steel and Aluminum Magnesium retainers, all of which are CNC machined to perfection and offer superior strength and stability.

    Ferrea takes great pride in offering premium quality Spring Seat Locators. Fully CNC machining in-house from 4140 chromoly alloy for different applications. Each piece is crafted to exact tolerances OD & ID specs and insure flat, parallel spring pad to the bottom surface. Heat treatment consists of a hard Nitrided surface for unmatched toughness and anti-wear characteristics.

    Works
    Color: Cocoa
    Good wallet that can fit a passport, hold cash, and cards. “Hidden” pockets too, but that just means more storage space to me. Soft and supple leather that gets better when conditioned and cared for properly. Main feature I like is the RFID blocking, I only get wallets that have it. Expensive- yes. Works, also yes.

    Really bad amazon customer service
    Color: Black
    The wallet seems great but the box it came in wasn't sealed. It was supposed to arrive by the 22nd and it arrived 4 days later. I needed it for a trip on the 1st. When I took it out, the wallet had two scratches at the back and the pen was also scratched. I contacted customer service and they couldn't help me in any way to get the replacement item before my departure date. I kept it anyways because of thr necessity. Gave it 3 stars because of the good quality of the wallet

    Great Wallet
    I'm pretty particular when it comes to things that I need to carry at all times when I'm out. When looking for a new wallet back in 2014, I initially went with the oft recommended Saddleback Leather Medium Bifold. Initially, that wallet seemed to be both durable and well made. Unfortunately, after several months in the back pocket, two things became clear: first, the leather was so taught that it was breaking my credit cards in half at the pinch point of the credit card slot. Second, what I took for durability in the thickness of the leather quickly turned into nuisance as I ended up with an inch thick brick that ruined my seating comfort. I called Saddleback regarding the first point and they told me that it was a known issue and if I didn't like it I could send the wallet back, which I did. That left me at a crossroads with a new requirement: I wanted a leather wallet that was thin enough to not be uncomfortable, held 6 credit/id cards and a handful of bills. I searched around until I came across Bellroy. The travel wallet seemed to check all the boxes and added some features I never knew I needed. After 6 years of use, I finally decided that the original travel wallet I bought in 2014 had run its useful life, down to holes in the leather and all. I liked it so much, I bought another one. There are some subtle differences which I will highlight below. 1. Fits in Your Pocket This is ostensibly the best feature of the wallet. It is large in the two dimensions you shouldn't care about and thin where it counts. I have not found a pair of pants that I would wear that it doesn't fit in. With my passport, 6 credit/id cards, and a dozen bills it is roughly 3/4 inches thick. Fabulous. 2. The Right Pen I had no idea how useful the pen would be. I find occasion to pull it out at least once a week. I used to carry the wonderful Fisher Space Pen, but no longer do as this fills the role in a much for optimized way. Bellroy is kind enough to include an ink refill with every wallet and I still have the refill from 2014. That's not to delegitimize the previous point; the kind of things I write are forms and other short memos. I wouldn't use the pen to write a novel. The new wallet looks to have a pen that Bellroy have either white labelled or made themselves. I haven't yet written with it, but if it is at least as good as the Walkie it replaced, things should be fine. 3. Added Security The new wallet takes the split billfold and adds a flap that conveniently hides away the back section from prying eyes. In theory this seems like a useful feature. In practice, the flap is not quite long enough to allow for more than one or two bills without the cavity being visible when the wallet is opened. The new wallet also has RFID shielding which I don't recall being a feature of the old wallet. It sounds like a useful feature now that at least one of my credit cards has a contactless payment feature. 4. Leather It's a thin wallet so you should expect the leather to be thin as well. I got 6 years out of the first wallet and I'm not a guy who is easy on wallets. It has been in my pocket on rooftops doing solar installations, in machine shops, and on every kind of seat imaginable. My old wallet has been fully submerged in water more than once. With all that punishment, it outlasted the warranty by two times. None of the stitching has failed and the only real damage is two small holes in the outer leatherwork. If you are a business traveler, this should go out of style before it is rendered unusable from wear. In short, this is a great wallet for everyday use. I approve to the extent that I didn't look for a new choice when my old one wore out.

    Very handy
    Color: Sienna
    I purchased it because I still use paper boarding passes. With luggage claim paper, your passport and ID card, things could get quite messy if you try to put everything in your bag or backpack’s compartment. This one organizes all those nicely. Because of its size it accommodates multiple boarding passes and luggage claim papers easily. (They used to get crumpled in international flights, and It annoyed me.). Yet it is compact enough to carry in your pocket. One negative is its price. It is expensive. But it is a quality product. Nice leather and well made. If you are willing to spend some $, this will spare you from searching your boarding pass and passport frantically at boarding. Highly recommend.

    Excellent product, great for travel
    Color: Cocoa
    I just got back from a business trip and this is by far the most useful passport holder/wallet I've ever used. Lots of room for cards, bills, boarding passes, and a second passport and still folds very flat. Leather is good quality, and is very well put together. Since its too big for my pocket and will mostly live in my briefcase, I expect it to last a very long time. The only drawback is the high price, especially since the leather is probably not full grain (it's not advertised as full grain, so we can assume it's not). But it fits my needs perfectly, even if it is a little overpriced.
