ARP kit # 201-5401

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.

All kits come with hardened parallel-ground washers and high quality nuts. 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-treated to create a fastener that has threads 2000% stronger than others.

Tech Tip:
There are a number of important considerations when installling ARP main studs. First and foremost is making sure the block and studs are as clean as possible. Foreign matter and debris can easily affect the quality of thread engagement and cause erroneous torque readings. Do not re-cut threads in the block - use the special 'chaser' taps instead. This will preserve the integrity of the threads and provide better engagement. Calibrate your torque wrench - even new wrenches have been known to be off by as much as 10 foot pounds! Use consisten tightening techniques.
