Nissan SR20DE/T ARP Main Stud Kit (202-5402)

Replace stock main studs with ARP heavy duty main studs. These main studs offers superior clamping force under high boost applications. A good upgrade when doing an engine rebuild or building a race motor. This kit comes with studs, nuts, and lube.
 

Note: Although this kit is designed for the SR20DET engines, on certain motors there are two studs on the rear driver's side that do not fit correctly (closest to the flywheel on the driver's side). They can be too long for the upper oil pan and protrudes into the pan itself. Proper cutting/shaving of the studs will be needed to ensure enough clearance. Always check for clearance of the upper oil pan and the block before applying liquid gasket maker or torquing down the bolts. If these precautions are not taken, the upper oil pan will either crack, bend or break resulting in excessive oil leaks near the rear main seal.

There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. All kits come complete with hardened parallel-ground washers and high quality nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.

ARP recommends the use of main studs over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don’t “twist” into the block. All clamping forces are on one axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life (very critical on aluminum blocks). Finally, there are factors of easier engine assembly and proper alignment of caps every time.
