Package with VMP 2.4" pulley, 90MM replacement idler, and VMP Ultimate Pulley Removal and Installation Tool. Full color instructions included in the tool case (behind the foam).
Includes 'stock look' VMP 2.4" pulley. Includes a black 90MM idler pulley that replaces the factory 75MM idler. This larger idler takes up the belt slack and provides better belt wrap. In our experience, an auxiliary idler bracket and pulley is not necessary, but can still be used with our pulley if desired. Our idler uses a bearing that is the same brand & size as the OE bearing, we have found that a single bearing is sufficient when a proper quality of bearing is used. Tuning required for 13-14 to see the additional boost, the factory 13+ plugs are already a colder heat range, but should be gapped down to .028-.035" to prevent spark blowout, stock gap is .045".
