1|This diffuser blade kit was curated by the professionals at Drake Muscle Cars to be installed with ease while having a dramatic styling to boost your S550's performance aesthetic. Designed to add to the already stylish Drake Muscle Cars Rear Diffuser (JR3B-6540544-A), this Blade Kit is the perfect upfit item to accentuate the S550's attitude. Not only does the styling complement the suite of Drake Muscle Cars' other S550 offerings, but it does so with an OE-style fit and finish due to its lightweight and blow-molded ABS construction. In addition, the unique bracket design will prevent blade alignment issues common to this type of item. 3|See the 'We Suggest' feature below to see more of the S550 Exterior offerings from Drake Muscle Cars. 6|Minimal drilling into rear valence is needed (not easily visible if blade kit is ever removed).
