Product Details

Earl's Performance Racing Products head bolts deliver superior strength and reliability for high-performance engine builds. Manufactured from premium 170,000 psi chromoly alloy steel, these bolts are approximately 15% stronger than standard Grade 8 fasteners, providing exceptional clamping force and durability under extreme conditions.

Key Features:

  • Premium chromoly alloy steel construction rated at 170,000 psi tensile strength
  • Hex head design with reduced wrench size for improved socket clearance around rocker arms
  • Wide flanged head distributes load across extra-thick chromoly washers
  • Reusable design eliminates the expense and hassle of OEM torque-to-yield bolts
  • Black oxide finish for corrosion resistance
  • Complete engine set included for full cylinder head installation

These head bolts are engineered for enthusiasts and racers who demand maximum reliability and performance. The reduced wrench size provides critical clearance when re-torquing cylinder heads with rocker arms installed, while the reusable design makes them a cost-effective upgrade over factory torque-to-yield bolts that must be replaced after each use.

Hard to find part, great price!

great pricing, hope I have the correct part number.

Cool

couldnt apply the 30 discount code for my purchase

Easy to navigate website and checkout was fast too. Very reasonable shipping. I just wish there would have been more product specific details under the "details" tab instead of just reviews.

I ordered a part that did not fit, returned no hassles. I just ordered two items and hope they look great.

Wow what a deal on mu Subaru husky liner floor mats and low shipping thanks Autoplicity
