Tomei Valve Springs - EVO X

Product Description

TOMEI Valve Springs; 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. Products developed with the most careful choice of the material, coating and the other technologies. Repeated severe tests to pre-production in order to give the best quality that is performed in any situations.

If you are running super aggressive camshafts that have high lift; you will require these special valve springs to provide the clearance needed. Covers all possible aspects for reliability and all conditions for any racing and street use. Tomei valve springs are constructed of a high tensile wire rod in the shape of an oval rather than the traditional circle. The result is a strong stiffer spring that compresses into a lower profile in order to provide adequate clearance.

Features reliability in high RPM and improvement in an initial response. High durability against metal fatigue, shocks from jump and bounce, surging, and also high sag resistance.
