In terms of transferring the exact movement of the camshaft, the highest quality valve spring is required to the high RPM, high powered tuned engines. TOMEI developed our products with the most careful choice of the material, coating and the other technologies. Then they repeated severe tests to their pre-production units in order to give the best quality that is performed in any situation.
Features
- 163022 - Valve Spring Set for RB25DET for Solid Camshaft
- Intake valve springs of RB25DET are short, so they are not used on the High lift camshaft. So only the intake uses the offset retainer and longer valve springs set on the cylinder head for getting the spring stroke.
We ship to the United States and 150 other countries.

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.
