When using Skunk2 Titanium Retainers on 2004 and newer engines, pre-2004 locks (keepers/cotters) must be used! Pre-2004 keepers can be identified by the absence of marks along the top edge (2004 and newer keepers feature laser-etched marks along the top edge). Proper retainer/lock selection is important due to varying angle ratios between earlier and later lock designs. Use of improper retainers and/or locks may result in serious engine damage.
