CV Savers neoprene CV protectors are an innovative design that are designed to protect your CV joint boot. Our CV boot guards feature quick and easy installation over your existing CV joint boot. The CV Savers can serve two different purposes. They can act as an additional boot for dual protection, or can be used as an emergency backup. Leave them on full time as a first line of defense over the CV Boot. Or, you can store them in a bag in your vehicle and use as needed. If you put a hole or tear a CV Boot, you can use the CV Saver as a backup or a Band-Aid to get you back home, or to the next pit- keeping the grease in and the dirt out. Zip Ties are provided to aid in installation.
