An adjustable pressure relief valve allows fine-tuning of oil pressure with the unit installed, ensuring optimal lubrication under various conditions. Quickee pushrods and S\u0026amp;S premium tappets facilitate precise valve operation, while the black-coated, hard-anodized tappet cuffs made from billet aluminum provide durability.
