This Bullet Speed product was designed to do one thing and that is to cover up the Polaris Slingshot parking brake spring. It really cleans up the drive side of your Slingshot. Use a 13mm deep wall socket to remove the stock bolt. [This is very IMPORTANT] Install the Bullet Speed Brake Cover with the parking brake in the released position (down). Slide the Bullet Speed Brake Cover over the stud and use the stock bolt to fasten the cover over the spring for a functional custom appearance!
