The present invention relates to a rear spoiler (300) which has a plurality of rib 5 structure (302) across the lower inner edge of the rear spoiler (300) to create relation between the spoiler (300) and the glass (304) of the rear gate. Further, each rib structure from the plurality of the rib structure (302) is uniformly distributed under the lower inner edge of rear spoiler at equal distance from each other. Base of the plurality of rib structure is in staggered shape to maximize 10 holding of cushion provided between the rib structure (302) and the rear gate glass (304). Further, the rib structure (302) has variable height with respect to gap between the rear spoiler (300) and the rear gate glass (304) to remove the un-even gap between the rear spoiler and the rear gate of the vehicle. 15 To be published with Fig. 3
