Universal Forge Motorsport Performance Blow Off Valve 50mm

Brand New Forge Motorsport Performance Parts and Accessories

This valve is the largest displacement valve that Forge currently produce. The unique design features a 50mm (2”) aluminium piston (meaning no issues with split diaphragms). As Forge endeavour to continue their innovation, existing products are no exception. Therefore, Forge has now released the all-new version of “FMDVRAY.” It has been difficult to improve upon this market-leading design, but Forge has done just that. Forge run this valve on their very own Mk1 race car, that’s how confident they are in the product!

  • Utilising world leading Eibach springs for more precise operation and consistency
  • A myriad of incremental engineering enhancements to all internal components have been carried out to offer faster response times and longer service intervals
  • The piston uses heat stabilised Viton O-rings
  • Lubricated with high-temperature Mobil1 grease to ensure a long life with minimal wear and very long service intervals
  • A super durable and responsive aluminium piston
  • A fully serviceable valve that is rebuildable in minutes
  • Ideal for custom installations using the aluminium weld-on coupler and clamp provided
  • Covered by the unique Forge Lifetime Warranty
