Engine Cylinder Head Bolt Set, Victor Reinz (Discontinued)

engine cylinder head bolt set using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with tty (torque-to yield) head bolts, replacement is an absolute necessity. Tty bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used. aplication summary: nissan - 1989-90 240sx l4 2.4l, 1990-95 axxess l4 2.4l, 1987-94 d21 l4 2.4l, 1987-88 pathfinder l4 2.4l, 1995-97 pickup l4 2.4l, 1990-92 stanza l4 2.4l, 1987-88 van l4 2.4l
