Product Details

The ARP 208-4701 head stud kit is engineered specifically for Honda K20A engines found in the Acura RSX. These premium head studs provide superior cylinder head-to-block clamping force, making them essential for high-performance applications including high-compression builds, turbochargers, superchargers, and nitrous oxide systems.

Premium Construction and Manufacturing:

  • Manufactured from premium grade 8740 chromoly steel alloy, far exceeding aircraft-quality materials
  • Precision heat-treated to 200,000 psi tensile strength for maximum durability
  • Centerless ground through approximately ten successive cuts to ensure near-perfect concentricity and straightness
  • Thread rolled after heat-treat process, providing 10 times better fatigue strength than pre-heat-treat threading
  • Specially undercut shorter studs equalize stretch characteristics for consistent clamping force across all fasteners

Performance Benefits:

  • Superior clamping force prevents head gasket failure in high-boost and high-compression applications
  • Precise tolerances allow cylinder heads and gaskets to align and install effortlessly
  • Consistent clamping force compensates for head gasket compression, ensuring optimal sealing
  • Dramatically improved fatigue resistance over OEM head bolts

ARP head studs are the choice of professional Sport Compact and Import racers who demand reliable head gasket sealing under extreme conditions. Each kit includes studs, washers, and premium ARP fastener assembly lubricant.

Springs came in on time, and seem to be great quality so far!

So easy you'll think you missed something.

nice site. all of the order was well packaged, no damage. i will be a return buyer.

easy website to use and find your part

Image of product is wrong but it did say image may be different. Part number should be correct for heater hose assembly, other wise site seems very good and understandable. Did receive correct part and very fast deliver, ordered Monday and received Wednesday, will probably use site again.

I ordered a chrome brake light cover from Autoplicity 3 days ago and received it today. Their add showed the piece I wanted clearly and it arrived today exactly as I expected. It looks great on my new Dodge truck. Thanks for the great service!

Autoplicity has an abundance of name brand parts at unbeatable prices. Customer service was also great to deal with. Receipt and tracking info was provided promptly.

Good
