ARP Main Studs offer the following benefits: \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e- Uniform Clamping Force:\u003c\/strong\u003e ARP Main Studs provide a uniform clamping force that OEM bolts cannot. With the improved distribution of pressure across main bearing caps comes better, more precise crank alignment for stability and longevity. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e- Improved Block Stability and Rigidity:\u003c\/strong\u003e ARP Main Studs improve block rigidity and therefore stability. This ensures maximum power transfer from the crank to the drivetrain, which in turn ensures: \u003c\/p\u003e\u003cp\u003e- Improved Throttle Response\u003c\/p\u003e\u003cp\u003e- Greater Horsepower\u003c\/p\u003e\u003cp\u003e- Higher Torque Output\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e- Prevent Main Cap Walk:\u003c\/strong\u003e This occurs as main caps shift and move out of position, which can cause crank and engine damage\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e- Reduced Risk of Fastener Stretching:\u003c\/strong\u003e Under high RPM applications and high loads, factory main bolts are prone to stretching and deforming. ARP uses advanced manufacturing techniques and high quality materials for hardware that is much less prone to deformation under load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e- Safeguard Engine Block Threads:\u003c\/strong\u003e Because ARP Main Studs have unmatched tensile strength, they are much less likely to deform or strip block threads under high loads. Additionally, ARP’s precision machining and manufacturing ensures that stud threads are both highly accurate and consistent. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eWhen opting for main studs instead of factory bolts,\u003c\/em\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cem\u003e it's important to note that the engine builder should mic the bores.\u003c\/em\u003e\u003c\/strong\u003e Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. \u003cstrong\u003e\u003cem\u003eThis is crucial for ensuring proper oil clearance and preventing premature bearing wear.\u003c\/em\u003e\u003c\/strong\u003e By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Instructions: \u003c\/strong\u003e\u003c\/p\u003e\u003col\u003e\n\u003cli\u003e\u003cp\u003eTo ensure accurate torque readings and proper thread engagement, thoroughly clean all threads in the engine block.
