3. Install New Studs: Insert the ARP main studs into their respective holes in the engine block. Apply assembly lube to the threads of each stud to prevent galling and ensure smooth installation.
4. Secure the Studs: Tighten the studs by hand and use a torque wrench to tighten them to the specified torque settings as per the manufacturer’s instructions.
5. Install the Main Bearing Caps: Place the main bearing caps onto the studs and install the washers and nuts. Tighten the nuts to the specified torque using a crisscross pattern for even pressure distribution.
6. Final Torque: Double-check that all nuts are torqued correctly and perform a final check to ensure everything is secure.
7. Test the Engine: After installation, turn the engine over by hand to ensure the caps are properly aligned and there is no interference.

Note: Professional installation is recommended for best results.

Maintenance Tips:

• Regular Torque Checks: Periodically check the torque on the main studs to ensure they are securely fastened.
• Lubrication: Ensure that the studs are properly lubricated during installation to prevent corrosion and ensure smooth operation.
• Inspect for Wear: Regularly inspect the studs for any signs of wear or damage, especially after high-stress events such as racing or aggressive driving.
• Engine Oil: Maintain proper engine oil levels to ensure lubrication of the main bearings, preventing excessive wear on the studs and caps.
