Nismo 3 piece SR20DET/KA24E/KA24DE engine and transmission mounts replaces missing, broken, or worn out OEM engine and tranny mounts. This 3 piece mounts are made with more rigid bushing material to ensure less vibrations from the engine and holds the transmission tighter for easier shifting at high RPM. This kit comes with the left and right engine mounts, and the transmission mount. These mounts also can be used with the KA24DE/E by switching the left and right engine mounts around. A recommended upgrade when swapping in an SR20DET motor to replace worn out factory mounts.
