Product Details

The ARP 193-4002 Pro Series head stud kit delivers professional-grade engine fastening performance using premium 8740 chrome moly steel rated at 200,000 psi. These competition-proven studs are the choice of top engine builders who demand absolute reliability in high-performance and racing applications.

Advanced Manufacturing Process:

  • Premium 8740 chrome moly alloy rated at 200,000 psi tensile strength
  • Vertical rack heat-treating ensures complete and uniform heat penetration
  • Centerless ground for exceptional concentricity and straightness
  • Thread rolled after heat-treat for 10x better fatigue strength
  • 12-point head design with wide area flange
  • Specially undercut short studs equalize stretch for consistent clamping force

Key Benefits:

  • Superior alignment during assembly—cylinder heads and gaskets glide into position
  • More accurate and consistent torque loading compared to bolts
  • Studs stretch only on vertical axis, eliminating torsional load
  • Wide area flanged head allows cylinder head retorquing without valve train removal
  • Helps prevent head gasket failures through optimized clamping force
  • Includes hardened parallel-ground washers for even load distribution

Each stud is manufactured to exacting tolerances and stamped with the ARP mark as assurance of quality. The kit comes complete with hardened washers and fasteners designed for competition use where reliability cannot be compromised. Remember to re-torque after initial engine run-in to compensate for head gasket compression.

Autoplicity did a great job. Fast shipping. Easy to order.

Great prices & fast shipping.

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.

Thought I had an issue with the customer service, and they worked it out PROMPTLY! That's a good customer Service relationship!<br>They even agreed to credit me my shiiping for a slight mistake they made!<br>VERY HAPPY!

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
