Product Description

The **ARP 203-4210 Head Stud Kit** is a premium performance upgrade designed specifically for Toyota and Lotus vehicles equipped with the 2ZZ-GE 1.8L DOHC engine. Built from ARP's proprietary ARP2000 material with an approximate 220,000 psi tensile strength, this kit provides significantly improved clamping force compared to factory torque-to-yield bolts, helping maintain superior head gasket sealing under high stress, high RPM, and forced-induction conditions.

This kit includes six 7/16in bolts, washers, and nuts, each coated with a black oxide finish for corrosion resistance and improved longevity. The pre-lubricated threads allow for precise torque application, ensuring proper preload and secure installation. Whether you're building a racing engine or upgrading your street vehicle, these bolts provide the reliability and strength needed for a secure flywheel connection.

Designed for high-torque and high-RPM applications, the ARP 203-4210 kit helps ensure the flywheel stays in place under the most demanding conditions, offering you peace of mind during intense performance drives.
