ARP Cylinder Head Stud Kit, 1.4L A14

The ARP 202-4203 is a Pro Series cylinder head stud kit engineered for Datsun and Nissan A14 1.4L I4 engines. These studs are cold-forged from premium grade 8740 chromoly steel to ensure molecular integrity and are heat-treated prior to thread rolling and machining. The black oxide finish provides a durable and corrosion-resistant surface. This kit includes hardened parallel washers, which are crucial for distributing clamping force evenly across the cylinder head and block, leading to more accurate torque readings and a more reliable seal. The 12-point nuts offer a superior grip for easier installation and tightening. Applications for this kit include a range of Datsun and Nissan models such as the 1975–1978 Sunny B210, 1976-1978 F-10, 1977.11-1982 Sunny HB310 (210), 1977–1982 Pulsar N10 (Cherry/310), 1977–1981 Stanza/Auster/Violet, 2007 LDV 1400 (B140), and 1978–1988 Vanette (PC120), as well as Datsun Forklift models with the A14 engine. The studs boast a tensile strength of 200,000 psi.
