Description

Earl's Performance cylinder headbolt kits are made from premium quality 170,000 psi chromoly alloy steel (about 15 percent stronger than Grade 8). These headbolts are reusable and are the ideal way to upgrade the performance of your engine, and eliminate the hassle and cost of replacing OEM-style torque-to-yield style bolts each time the cylinder heads are removed. Order the kit recommended for your year, make, and engine application.

Features include:

* Material—chromoly alloy steel
* Yield strength—170,000 psi
* Finish—black oxide
* Reduced wrenching size—provides extra socket clearance
* Choose from 12-point or hex head-styles
* Wide flanged head provides more support for the extra-thick chromoly washers
* Includes premium headbolts, washers, and anti-seize lubricant
* Sold in complete engine sets
* Reusable headbolts and washers (not torque-to-yield)
