Who We Are
In April 2014 a small group lead by John Silseth and Colbert Seagraves purchased the USA operations of Langcourt Ltd. to offer a wide scope of cylinder repair and cylinder head performance products and services for racing or street use. With over 26 years of industry experience we currently provide services to over 2,500 dealers across the country. Known for our own nickel silicon carbide plating formula developed in racing applications from Motocross to Formula 1, Langcourt offers the best nickel silicon carbide cylinder plating technology in the market place today.
We have recently invested in new state of the art CNC equipment that allows us to now offer 5-Axis CNC porting, big bore kits and the quickest turnaround time in the industry: Guaranteed 5 Business Days!* Our competition can’t even come close to that without charging a rush fee or exchanging your cylinder.
Built on our racing heritage, “Where Winning is Everything,” we deliver racing technology, services, and products from Motocross to Formula 1 and everything in between. Langcourt Performance provides, to the powersports and motorsports industries, the finest cylinder technology based products and innovative services in the world.
We are aligned with some of the greatest names in motorsports: Danny Lawrence, 17X NASCAR Championship Engine Builder and builder of the 1998 Daytona 500 race-winning engine of Dale Earnhardt; Matt Smith, 2X NHRA Pro Stock Motorcycle World Champion; Rickie Smith, 11X IHRA and NHRA Pro Stock and Pro Mod World Champion; and Mike Lozano of Lozano Brothers Porting, 5X Winning Engine Builder of the 24 Hour of Daytona endurance race.
