Welcome to Terra Firma Automotive, your premier destination for high-performance parts. Introducing the ARP Head Stud Kit ARP2000 Pro Series for Nissan RB25, part number 202-4309. Trusted by top professional engine builders worldwide, ARP Pro Series head studs are the ultimate choice for all-out competition powerplants.

Crafted with precision, each Pro Series bolt undergoes cold-forging to ensure unmatched molecular integrity. Prior to thread rolling and machining, they are heat-treated for exceptional strength, boasting a nominal rating of 200,000 psi. These fasteners are specially designed for competition-only components, meeting ARP's stringent "ZERO defect – ZERO failure" quality standard.

With hardened and parallel-ground washers included, you'll experience even load distribution and accurate torque readings. The reduced wrenching hex or 12-point head, along with the wide area flange, eliminates the need for valve train removal during cylinder head retorquing, accommodating larger diameter valve springs.

Terra Firma Automotive takes pride in offering the finest quality materials. Each head stud is forged in-house at ARP, precisely CNC-machined to exacting specifications, and threads rolled after heat-treat for unmatched fatigue strength.

Upgrade your Nissan RB25 engine with the ARP Head Stud Kit ARP2000 Pro Series from Terra Firma Automotive and enjoy the pinnacle of reliability and performance. Shop now and experience the power of excellence with Terra Firma Automotive.
