Product Details

The ARP 203-4701 head stud kit is engineered specifically for the 1986-1992 Toyota Supra MK3 with the 7M-GTE turbocharged engine. These undercut head studs provide superior clamping force and reliability for high-boost applications, preventing head gasket failure in turbocharged, high-compression, or power-adder setups.

Premium Construction and Materials:

  • Manufactured from premium grade 8740 chromoly alloy steel, rated far superior to standard aircraft-quality fasteners
  • Precision heat-treated to 200,000 psi tensile strength for maximum durability
  • Centerless ground through approximately ten precision cuts to ensure near-perfect concentricity and straightness
  • Thread rolled after heat treatment for approximately 1000% better fatigue strength compared to pre-heat-treat threading
  • Special undercut design on shorter studs equalizes stretch for more consistent clamping force

Performance Benefits:

  • Superior head-to-block sealing for turbocharged applications
  • Compensates for head gasket compression to prevent blown gaskets
  • Precision tolerances allow cylinder heads and gaskets to align perfectly during installation
  • Optimized for high boost, nitrous oxide, and other power-adder applications

Application:

  • 1986-1992 Toyota Supra MK3
  • 7M-GTE turbocharged engine (U-cut design)

ARP head studs are the preferred choice among import and sport compact racers who demand maximum reliability and consistent clamping force in high-performance engine builds.

Order filled promptly. Very pleased with purchase. Highly recommend Autoplicity!!

The description for the Trimax adjustable receiver hitch did not always include the drop and had to be gleaned from the part number.

1st order. Shipped super fast and prices are amazing. I will be back for sure.

Great customer service. Quick process and shipped les than 24hrs after order. 5 stars.

Autoplicity had exactly the part I was looking for, for my SRT8 Challenger, at the best price I could find!

Ok so far

Quick, cheap, and accurate. What else do you need?

Great prices and FAST shipping!! Definitely will buy products here again!

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.
