Cylinder head studs are used in factory and sports engines to mount the cylinder head and allow you to remove / install the cylinder head multiple times. High-strength cylinder head studs are also used in powerful engines for tuning. Reliable cylinder head mounting allows you to get high engine power during tuning and avoid damage to the gasket between the block and the cylinder head. The head studs can be installed instead of the factory cylinder head bolts, which are less durable and can be used once, in contrast to the studs, which allow the cylinder head to be removed / installed repeatedly on the engine. 7.3 Head studs are the most common type of engine studs to date and people often replace them in their engine.

We produce high strength cylinder head studs to order according to drawings or sample. Our studs have high strength characteristics and withstand a breaking load of at least 1700 N / mm2 (170 kgf / mm2) , which allows them to be used on engines with a power of more than 1000 hp. , as well as to be used on highly loaded engines with high pressures of more than 3 bar.

Below you can familiarize yourself with the description and full characteristics of JTlab studs, see a comparison of ARP 8740 studs and JTlab studs, as well as see photos and videos of testing our studs.

An engine failure is an event that always promises trouble and requires important decisions to be made:

Is it worth spending money on replacing or repairing the engine, or would it be more expedient to get rid of the old car altogether and buy a new one?

Is the old engine fit for repair or will you have to replace it with a new, remanufactured or used one?

Which option is better and more reasonable from an economic point of view?

If your car is less than ten years old and you are very attached to it with your soul or you cannot afford another at the moment, then perhaps the best solution for you would be to repair or replace the old engine. Cars quickly depreciate, even if they are not used too often. By the time your car needs a new engine, its market or trade-in value may be so low that it becomes unprofitable to transfer the extra money to it. Therefore, if your car costs less than $ 2,000, think very carefully before spending on a major overhaul. Better save your finances for buying a new car.

On the other hand, if your old lady has served more than ten years and you can’t stand her anymore or are looking for an excuse to get a new car, don’t spend a dime on her. Forget about repairing and replacing your old motor. Recycle it or donate to charity to get the tax off, or sell it cheap to someone who thinks they can fix it and get it back on its feet.

If an old engine has run over 150,000 miles and burns oil, malfunctions, noises, or stalls, repairs will be expensive. To reconstruct an engine with a high mileage, it will be necessary to bore the cylinders for new larger diameter pistons. In this regard, the costs of spare parts and car service will increase. It may be necessary to re-bore coaxial holes in the cylinder block to restore their rounded shape and alignment. Milling and grinding of the mating surfaces may also be necessary to ensure that they are flat. It will be necessary to restore the surface of the cylinder heads, replace the exhaust valves (possibly the valve seats if the head is aluminum), it may be necessary to bore the camshaft holes along one axis to restore the bearing surfaces.
