ARP Head Bolt Sets Editorial Review
The ARP 247-4202 Stud Kit is highly regarded among customers for its quality and performance, making it a preferred choice for those upgrading their 5.9 and 6.7 Cummins heads. Reviewers frequently highlight the tight clamping force provided by these studs, which instills confidence when applying higher power tuning on their vehicles. The installation process is generally described as smooth, albeit requiring a fair amount of torque wrench work which some may find tedious. Many users appreciated the clear and informative instructions provided with the kit, along with the included assembly grease, although a few noted that they opted for a larger container to facilitate a less messy installation. Customer satisfaction is also echoed in their peace of mind regarding engine integrity, especially when pushing their vehicles to higher power levels. The stud kit is seen as a valuable investment to prevent head lift and maintain coolant levels effectively, showcasing its reliability in enhancing engine performance. While the installation can be time-Consuming, particularly due to necessary preparatory work like removing valve covers and adjusting rockers, users found that with careful planning and some additional resources such as online video tutorials, the process becomes manageable. In summary, the ARP 247-4202 Stud Kit stands out as a quality product that not only meets expectations but enhances driving confidence for those working with more powerful tunes on their Cummins engines. **
