Why choose new head bolts over reusing existing bolts during cylinder head service?
Choosing the new Cummins ISX head bolt kit 3678506 over reusing existing bolts is critical for maintaining proper cylinder head integrity and preventing costly engine damage. Head bolts stretch during use and lose their ability to maintain proper clamping force, which can lead to head gasket failure, oil leaks, and overheating. New bolts ensure optimal torque retention and sealing performance while being inexpensive compared to potential repair costs. With ASE-certified technical support and premium aftermarket quality, this head bolt kit provides peace of mind for reliable long-term engine operation.
