Pro Series Head Bolt Kit

The ARP 204-3902 is a Pro Series head bolt kit engineered for enhanced performance and reliability in VW 1.8L turbo 20V M10 engines. These bolts are manufactured from premium chromoly material and undergo a rigorous cold-forging process to ensure maximum molecular integrity. They are then heat-treated prior to thread rolling and machining, resulting in an impressive tensile strength rating of 190,000 psi. The kit comes complete with hardened parallel washers, which are essential for distributing loads evenly across the cylinder head and ensuring accurate torque readings during installation. This attention to detail helps prevent cylinder head distortion and gasket failure. This specific kit, part number 204-3902, is application-specific and designed to fit a range of Volkswagen and Audi models equipped with the 1.8L turbo 20V engine. It includes an integrated installation tool, simplifying the process for mechanics. The fasteners feature a black oxide finish for corrosion resistance. Applications include: 2004 Audi A3, 2004-2006 Audi A4, 2004 Audi S3, 2004-2006 Audi TT, 2004-2005 Volkswagen Beetle, 2004-2006 Volkswagen Derby, 2004-2005 Volkswagen Golf, 2006 Volkswagen Golf GTI, 2004-2005 Volkswagen Jetta, 2004-2005 Volkswagen Passat, 2004-2006 Volkswagen Pointer, 2004-2006 Volkswagen Pointer Truck, and 2004-2006 Volkswagen Sharan.
