Note on replacement parts:
The idler pulley included in this package is a unique offset. The standard VMP 75 mm, 90 mm, and 100 mm do not fit. Additionally, many companies have made aux idler brackets for the GT500, because it is an add-on part each brand has a unique design. For replacement idlers for the VMP version see kit PN: 555-3368 Billet Idler, standoff, and T-slot slider assembly.
