ARP Nissan RB Main Stud Kits

The ARP RB Main Stud Kit (RB20, RB25, RB26, RB30) is available in either premium grade 8740 chrome moly or ARP2000, and include hardened parallel washers for an even load distribution and accurate torque readings.

8740 Chrome Moly: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now, 8470 is viewed as a moderate strength, good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard practice in the manufacturing of this kit. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.

ARP2000®: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.
