Tomei Valve Spring Sheets
The Tomei Valve Spring Sheets enable to the fine tuning of the valvetrain when installing aftermarket valve springs.
The Tomei Valve Spring Sheets enable to the fine tuning of the valvetrain when installing aftermarket valve springs, ensuring consistent and adequate spring load specifications for a freely revving engine.
Features
When installing aftermarket valve springs in a head assembly, the amount of load applied to each spring needs to be adjusted until everything is in uniform specification. This is a standard procedure which all race engines go through in order to be able to raise the engine RPM without any glitches or hesitation.
The standard method involved when putting together the valve assembly is to fully balance all the added components to tighter clearances than the manufacturer specifications. This method called “blueprinting” can be time consuming and a very costly service performed by an experienced engine builder.
By utilizing the various thickness of the spring sheets to adjust to each and different spring rate load, the same objective can be satisfied with fraction of the cost.

About Tomei
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.
