ARP Pro Series Main Stud Kit (Nissan SR20DET) | Niced Up

Eliminate main cap walk and fretting with the ARP Pro Series Main Stud Kit (Part # 202-5402) for Nissan SR20DET 2.0L Turbo engines. Main studs provide far more accurate torque readings than OEM main bolts because studs do not twist into the engine block during torque-down, resulting in superior crankshaft alignment and cap retention under high boost.

Manufactured from 8740 chrome moly steel and heat-treated in-house to 190,000 psi tensile strength, this kit features precision J-form threads rolled after heat-treat for unmatched strength and thread fatigue resistance.
