Speedfactory extreem L19 head studs/head bolts (K20/K24 engines)
90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
This Kit was designed for hardcore drag racers running high boost levels that need more clamping force and tensile strength than the typical 8740 chromoly studs on the market.
If you are looking for the best option, you've found it as these are 25% stronger than any other available off the shelf Head Stud Kit for your Honda/Acura!
These studs are manufactured specifically for us by ARP and utilize an L19 material that is much stronger than the typical 8740 chromoly and yields a tensile strength of 240-260,000 psi. They are also provisioned with a hex broach on the top of the stud for ease of installation and enabling you to install them with the cylinder head on the car if necessary.
What makes these head studs better than the competition?
Initially these might look just like other ARP and A1 Technologies head studs available on the market, but that isn't the case.
- Superior L19 Alloy steel, much stronger than the typical 8740 chromoly.
- Achieve higher clamp loads of 240,000-260,000 psi as opposed to the competitions 190,000-210,000 psi rating.
- Hex broach on the top of the stud for ease of installation.
- No Modification to your cylinder head or block is required as these are a direct drop-in replacement for the OEM head studs.
- Recommended for applications boosting higher than 30 PSI.
Each kit includes a complete set of L19 head studs, nuts, washers and ARP Assembly Lubricant.
