Product Details

The ARP 250-3009 cylinder head stud kit delivers the superior clamping force and reliability needed for high-performance engine builds. Engineered by ARP, the fastener experts trusted by professional engine builders and racers worldwide, these premium studs ensure your cylinder heads stay sealed under extreme combustion pressures and temperatures.

Key Features:

  • Manufactured from premium grade 8740 chrome moly steel for exceptional strength and durability
  • Heat-treated to 190,000 psi tensile strength for maximum clamping force
  • Precision-machined threads rolled after heat treatment to prevent fatigue failure
  • Includes hardened parallel-ground washers for even load distribution
  • Black oxide finish for corrosion resistance
  • Allows for more accurate and consistent torque readings compared to head bolts

ARP studs provide more accurate torque loading than conventional head bolts because the fastener is not twisted during installation. This eliminates the torsional stress that can cause inaccurate torque readings and potential failure. The studs stretch uniformly along their length, providing consistent clamping force across the entire head gasket surface. Each kit includes premium-grade nuts and washers for complete installation.

Installation Note: Always use ARP Ultra-Torque fastener assembly lubricant or ARP moly paste on the threads and under the nut face for proper torque values and to prevent galling. Follow ARP's torque specifications and tightening sequence for your specific application.

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

The best price I could find and it arrived in 2 days! I'll be doing business again.

They have the best prices and fast shipping too.

Excellent low price, super fast shipping, and great communication. Top notch seller. Recommend highly!!

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

Best price found quick shipping couldn't be easier will buy again.

they had the lowest price for the helmet i was looking at by more than $100. easy to order by phone and quick shipping. i already recomended them to a friend who also needs a new helmet. i will purchase from them again.

Had just what I wanted at a very good price when I compared it to others (part plus shipping). Will try them next time I need parts.
