Due to the installation of the high lift cam and the high revolution of the engine, the cam cap adds an enormous force trying to lift it. The reinforced cam cap bolt secured the mounting strength to clear the 12.0 mm lift 10000 rpm by using the bottomed stud bolt and chromoly material. Conventionally, when assembling high lift cams, I was worried about deterioration of workability and damage of head screw holes due to insufficient total length of bolts, but this product secured high maintenance by lengthening the whole length. |
