Tomei cam bearing cap studs are made from chrome-moly and are equipped with a flat bottom, that allows 12.0mm of lift at 10000rpm.
Once installing high lift camshafts and other modifications to the engine, excessive force is added to the cam bearing cap. Strengthen cam bearing cap studs are made from chrome-moly and are equipped with a flat bottom, that allows 12.0mm of lift at 10000rpm. When using standard studs at the time of maintenance damage on the head screw hole from the bolt being too short may occur. When installing high lift cams though, it allows easy maintenance by prolonging the bolt length.

Tomei was founded in 1968 by members of the Johoku Riders motorcycle club, among them Nissan works driver Seiichi Suzuki. It began as a racing engine builder for Nissan engines only, and its work on the Nissan L-series and later the RB and SR engines made its name. The company took the name Tomei Powered when it moved to Machida, Tokyo, in 1994.
Tomei now develops parts for many Japanese engines, Mitsubishi, Subaru and Toyota as well as Nissan: camshafts, valve train parts, pistons, connecting rods and crankshafts, complete engines, and exhaust systems such as its well-known Expreme titanium range.
