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 we endeavour to continue our innovation, existing products are no exception. Therefore, we have now released the all new version of “FMDVRAY.” It has been difficult to improve upon this market leading design, but we have done just that. We run this valve on our very own Mk1 race car, that's how confident we are in the product!

Highlights:

  • Improved external aesthetics
  • 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
  • Available in anodised black or anodised purple 
  • Ideal for custom installations using the aluminium weld on coupler and clamp provided
  • Covered by the unique Forge Lifetime Warranty*

Too Much Back, Ain’t Enough Slack
Color: Brown, Size: 36W x 30L
Sadly the color doesn’t quite match the photo—it looks cheaper IRL. However, the form of the pants are cool, but they don’t fit me. TLDR: These pants aren’t for guys with back. Good looking style though.

Color was off. More plum than burgundy
Color: Burgundy, Size: 36W x 32L
The color was more plum than burgundy. I returned them. Not a plum pants kind of guy. I have gotten other colors. I actually love the fit.

Do not trust sizing or measuents
Color: Black, Size: 32W x 30L
Sizing way off. Can barely fit on and no where close to buttoning. Same pant measurements in another pant bought at the same time no problem. Sizing and measurements off.
