Installation difficulty: 2
Our technicians have determined that the installation difficulty level of this item is a 2 on a scale of 1-5. Read more about our install ratings here.
Almost no effort. Either snap on or plug and play. Probably no tools involved.
Simple installation with common tools. Probably less than 20 minutes for installation. Easy enough for
anyone who can read and follow instructions. A good first project for someone with no experience. Hard
to mess up.
A little mechanical experience is helpful but not necessary. Possibly a good first project for those with
a little more confidence. Will probably take more time (20-60 minutes) than #2.
Mechanical experience a definite plus. Not a good first project for the inexperienced. Most likely a 2-3
hour job minimum.
Only for the experienced wrench. Most likely requires good tool collection, possibly special tools and
a fair amount of experience. 95% of people will choose to have this installed by Zip or a professional.
