High Quality Camshaft Sprocket Bolt

The GM bolt is metric class 12.9 material. It is rated nominally as 174,000 psi tensile strength.

Our camshaft sprocket bolt uses 8740 chrome moly steel material. This material has a tensile strength rating of 190,000 psi. It is rated with 8% more tensile strength than the GM bolt. The bolt is custom made by ARP.

The installation procedure is the same as for the GM bolt. The GM bolt requires about 90 foot pounds of torque as the 80 degree rotation specification is reached. Be prepared for more torque with the chrome moly bolt. It requires about 110 foot pounds of torque as the 80 degree rotation specification is reached.

Do not turn the bolt more than 85 degrees because the clamping force will be reduced.

As with the GM bolt, this is a torque to yield installation. A new bolt should be utilized with every installation.

The cost is $17 each.
