Description
From the sellerThread Size: M12 x 1.75 Material: Stainless steel These lock nuts are precision-engineered to withstand heavy vibrations and extreme heat. They are primarily used for mounting the turbocharger to the exhaust manifold on Cummins High-Pressure Injection (HPI) fuel systems, specifically for 15-liter ISX and QSX engines (EPA07 automotive models). They are also compatible with select Mack E7/ASET and Volvo engine series assemblies.
