⚠️ Technical Build Warning (Read Before Purchasing)
Because ARP main studs provide vastly superior clamping force compared to factory hardware, installing them changes the internal shape of your engine block's bearing bores and a Line Bore is highly recommended.
-
Machine Shop Requirement: Your engine block must be align-honed after installing these studs.
-
Assembly Protocol: Always carry out final align-honing using the exact same fasteners, washers, and ARP Ultra-Torque assembly lube packaged in this kit to guarantee concentric bearing bores.
