fits all 2000+ 1.8t 4-cylinder 20-valve heads with 10mm threaded bolts - M10

Brand Description:

USP Motorsports is pleased to offer the highest quality fasteners from ARP. ARP’s product line contains thousands of part numbers, and has expanded to include virtually every fastener found in an engine and driveline and throughout the suspension and frame. These range from quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications.

Product Description:

ARP uses premium grade 8740 alloy that is rated far superior to that of supposed "aircraft" quality. All Pro Series ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi. These fasteners deliver a 40% increase in tensile strength over the OEM Torque to Yield (TTY) bolts. All bolts are precision centerless-ground and thread-rolled to Mil-S-8879 specs. Each utilizes a black oxide finish that protects them from wear and corrosion.

Obtaining the optimum cylinder head-to-block sealing is critical in small displacement engines employing high compression pistons or engines that utilize high pressure outuput from forced induction

Important: These head studs do NOT use the factory 6-point tool for tightening. Do not use the factory tigntening torques or procedures for these head studs, instructions supplied!

Price for complete set for one head, also available with 12-point tool, see option below.
