Description

The Jim Wolf Technology AVG3E-L6SPR is a set of 12 heavy-duty outer valve springs engineered for high-performance applications. These springs are designed for use with JWT L28, VG30E, and VG33E(R) camshafts. They are harmonically tuned and do not utilize an inner spring, offering a maximum lift capability of .600" (15.24mm). Installation requires the use of OEM factory retainers and valve spring shims, which are not included with this kit. The inner diameter (I/H) for these springs is 1.575". This valve spring set is compatible with a range of vehicles including the 280ZXT, 300ZX (Z31), M30, Maxima, Pathfinder, Truck, and Xterra, specifically for the L28ET, VG30E, and VG33E engines. These springs are often recommended for use with specific Jim Wolf Technology camshafts, such as the AZ314-000S2 VG30E(T) CAMSHAFT and A280Z-00C1M BILLET CAM 280ZX L-6.
