Upgraded replacements for the upper and lower stock timing belt idler pulley pulley studs on all VG30DE(TT) engines.
The Ramey Z upgraded studs are designed to reduce the stress on the stud by distributing the load across a larger area. They are machined from grade 8 steel for strength. Due to the design and material they are less likely to break than the OEM idler pulley studs.
Apply a conservative amount of locktite and torque the nuts that hold the idler pulleys on to factory specified torque settings.
