The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize the wear that naturally occurs between the roller tip and the valve stem.

Note in picture the clipped ends of the roller pin.  All the cheap less than 0 rocker arms are simply pressed in which are prone to stress cracks that will ultamately result in failure. I have seen many sets that are already cracked in the box.
Please read:
We at KMJ had been forced for years to sell the junk red and gold die cast rocker arms that have dominated ebay. We said enough was enough!! We were tired to the junk coming to us that was already broken in the box. If the quality controls were not in place to make sure the rocker arms were not cracked before they went into the box what was really happening during production. Most of the rocker arms being sold by our competitors will not handle near the spring pressures and RPM they advertise. Most wont even handle a moderate hydraulic camshaft. This is because they are die cast out of cheap aluminum instead of a 100% extruded aluminum.
We went on a mission to find the highest quality extruded aluminum roller rocker arms available to us. We found the manfacturer who manufactures for another very well branded company.   They retail their rockers for 8.50 and they come in a different color.    For them to manufacture them for us and at a price we could pass on and be competive we had to purchase 1000's of sets and make them in a different color.
They cost us significantly more than the other Junk on ebay. Most the other junk on offered on ebay we can buy for - a set.
Lots of profit for sellers not to profitable for you as the customer!!! Those of you and their are quite a few of you who do not trust a less than 0.00 rocker arm set in your 00 engine, do not worry as you will not find a better aluminum roller rocker arm than what we are offering.
Of course at this point you probably think that we are simply blowing smoke in order to get you to pay more for the same pile of crap everyone else is selling.   As the old saying goes a picture will say a 1000 words. Please study the pics very closely what we are trying to provide you is a comparison of the competitors rocker arms and what we are offering. The captions of the pics will point out the differences.   Most other sellers may take wonderful pics of their own and make claims that are in their opinion uncontested. We want to show you them side by side and then let you make the decision.
They are all nice and shiney and take good pics but they are not all equal!
The one we are selling is the 4th rocker arm in from the left. The 4th and 5th one are identical expect in color. Remember we had to make them a different color!! Check out the retainer clips on our beefy roller tip pins.   The beefy pin and retainer clips cost more but ensures that at high RPM and pressure that the pins will not work themselves out. If you have raced enough you probably have heard of these pins walking out.   Some racers don't even notice that it was the pin that came out that destroyed their engine. They think they simply dropped a valve. Here is what happens with the small press pinned design. The pin comes out and shortly after the rocker arm is simply riding on the spring retainer. The valve tip gets pressed into the area the pin and roller should be. The piston ends up catching up to the valve and smacks the valve possibly breaking the top of the piston or busting the valve and sending it into the head and shortly after you have a fireball. Whos to blame? The manufacturer of the rocker arm? The engine builder? Our you for thinking for 0 you can get a rocker arm that will withstand the intensive and extreme abuse that a race engine is subjected to.
Check out the roller tip oiling holes. The two on the left are OK but they are a little high to ensure proper oiling. The third one is completely unacceptable as it is highly unlikely it will ever get any oiling. The fourth and 5th one have the hole in the proper postition to ensure that the roller tip and the valve tip get the oil they need to reduce friction and fatigue.
Race engine or saturday night cruiser do you really want to save money on something that has the potential of costing you 00's in the end!

The majority of Paypal payments can be processed within 2-3 hours after received during our normal weekday business times.  To prevent any delays with your order you should watch for the following common issues:
Be sure your shipping address has a physical address that Fedex/UPS can deliver to.  Addresses that only have a PO Box can cause long delays and almost always result with having to credit/cancel the order in the end.  You should be able to add one onto your payment when going through the payment process.
Be sure the shipping address is correct when making payment.  Shipments will go to the address that comes through on the payment.  Within a short time it may be already shipped and on the way.
Some of our listings may request a "note to seller" to let us know if you have a certain preference or need a specific thing such things as sizes, colors, etc.  Putting a note on your Paypal payment is the best way to insure it should not be missed.
In order to comply with Paypal's buyer/seller protection policy, any (single) payment having a total of 0 or more must be sent with signature confirmation on delivery.

to all packages that may be associated with the payment.
