Low Profile Valve Cover Hardware kits are a comprehensive design, featuring specially engineered “standoffs” that include provisions for Skunk2’s unique, low-profile washers and flush-mounted, stainless steel hardware. Each kit includes 12 low-profile billet aluminum washers and 12 flush-mounted, stainless steel bolts. All kits are compatible with OEM valve covers as well as OEM and most aftermarket spark plug wire covers. Each OEM-grade standoff replaces the factory mounting studs and is secured to factory specifications. No other valve cover kit available does this. A series of Viton O-rings and the appropriate standoff extensions are included with each kit to ensure a leak-free seal and OEM fit and finish.
