The EV0 2 is All new! The mounting is redesigned, the deflector is a more streamline shape, basically the guys at Enduro Engineering went out of their way to deliver an improved product that checks all the boxes with performance in mind. The new roost shields are easily mounted to your aluminum deflectors with two screws The composite mounting plate gives both a solid mounting surface and adds strength to the plastic deflector. The new shape is intended to be both stylish and to reduce the bulk of other deflectors. The top and bottom edges are rubber over-mold to allow the deflector to flex under impact. If you purchase your new EVO 2 Deflectors with a set of new EVO 2 Aluminum Guards, they will be pre-drilled and tapped for easy mounting. If you are adding the EVO 2 Deflector to an existing pair of aluminum guards (as we did) Enduro Engineering provides both the drill bit and self-tapping screws in the kit. A few mounting tips: First, if drilling, mock up the deflector then use a sharpie marker to mark where to drill. Second, be very careful not to over tighten the self-tapping screws. When the head of the screws sit flush in the mount there is no need to tighten any further.
