Product Details

The ARP 202-4206 High Performance Cylinder Head Stud Kit is a chrome moly head stud kit made from 8740 alloy steel with a 12-point nut style. It is designed for engine builders who want accurate, consistent clamping force and easier cylinder head and gasket alignment during assembly.

Key Features:

  • 8740 chrome moly steel: premium alloy, heat-treated with each stud racked vertically for complete heat penetration.
  • Centerless ground: after heat treatment, each stud is centerless ground for a very straight, concentric part, so gaskets and cylinder heads settle into position and stay aligned.
  • Thread rolled after heat treatment: ARP states this gives substantially better fatigue strength than studs threaded before heat treatment.
  • 12-point head design: a reduced wrenching profile that, per ARP, helps eliminate the need for valve train removal when retorquing the cylinder heads.
  • Hardened, parallel-ground washers: supplied with High Performance Series kits for even load distribution and accurate torque readings.
  • Specially undercut shorter studs: on engines where ARP offers them, undercutting evens out the stretch between short and long studs for more consistent clamping force and to compensate for head gasket compression.
  • ARP stamped: look for the ARP marking on each stud.

Studs vs. Bolts: For most applications, ARP recommends studs. They make assembly easier, keep the head and gasket properly aligned, and provide more accurate, consistent torque loading because the stud stretches only along its vertical axis while the nut is tightened. Install studs finger tight rather than cranking them in with a jammed nut. Because the head gasket compresses on initial torquing, re-torque after the engine has been run.

The ordering process was pretty straight forward & simple. Searching for tires on the other hand was a bit more complicated, as the search filters didn't work so well. Shipping was fast, but there was a typo on the shipping label that caused a delay. This is what necessitated the call to customer service to correct that. Nothing bad, as we're only human, but was easily fixed with the phone call.

very easy to find exactly what I was looking for. TOM P.

I've only clicked the place order button so far.

Fast shipping

Nice and easy

good price and easy

Received product fast was exactly what I needed thanks

Product was as described.

Great service, cheap prices and fast shipping. I will repeat.

Prices are among the lowest around. Had a change with my order. Customer support team was quick to respond to emails and make corrections. Will order from Autoplicity again.

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

My order had a delay. I believe this was due to the fact that it was shipping from the manufacturer so I can't really blame Autoplicity. The customer service team did not originally respond to my first e-mail, but they did respond to me once I opened a dispute in PayPal and the issue was resolved. I couldn't find a better price on the part I ordered though (or anything remotely near that price for that matter).

Autoplicity has made my parts search so much easier. With the best price gurantee, i can now make autoplicity my one-stop shop for all my parts needs.

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.
