Preparation requires a standard set of hand tools, a clean workspace, and an extra pair of hands to help position the lightweight upper carbon fiber lip and durable HDPE lower splitter. The most important thing to watch out for is aligning the threaded inserts on the RKP upper lip with the Fall-Line lower splitter to achieve the desired two inches of forward or backward adjustability without scratching the 2x2 gloss carbon finish.
