Valve Seat - 2.460 x 2.000x .375

The DART Valve Seat – 2.460 x 2.000 x .375 (Part No. VS2460) is a precision powdered metal intake valve seat engineered for high-performance engine applications. This component delivers OEM-grade dimensional accuracy and material integrity, serving as a drop-in replacement or performance upgrade for engine builders, race teams, and powersports enthusiasts who demand exact valve-to-seat geometry for optimal combustion sealing and thermal management.

Manufactured from powdered metal, this valve seat provides superior hardness and wear resistance compared to cast alternatives, critical for maintaining compression integrity across extended duty cycles. The 2.460-inch outer diameter and 2.000-inch inner diameter specifications are precisely controlled to ISO standards, ensuring repeatable fit in OEM and performance cylinder heads. The 0.375-inch thickness is designed to absorb thermal cycling and valve impact without deformation, maintaining seal quality under sustained high-RPM operation and elevated combustion temperatures. Each seat is individually machined to specification, eliminating variability inherent in bulk casting processes.

This valve seat is suited for engine rebuilds, stroker builds, and performance restorations where original factory seats have worn or require replacement to specification. Professional engine machinists and tuners rely on DART valve seats to restore compression ratios and combustion efficiency without custom porting or boring. The powdered metal construction also resists corrosion and galling during installation, reducing machinist labor time and risk of bore damage during press-fit operations.

DART valve seats are recognized in the engine building community for consistency and dimensional reliability across production runs. This part is sold individually—verify application compatibility and press-fit tooling requirements with your engine's manufacturer specifications before ordering.
