I also had the dealership install my lift. After walking past a Tacoma in the lobby that was jacked sky high, I started a conversation with the service manager. I Asked them who did the work for them, warranty, cost, time, etc. I was expecting them to refer me to the local off road shop thats been in town for years, but I was shocked when he said they do them all the time right there. I made the appointment to have it done the next day and couldn't be happier with what I got.
Some dealers are great.....others not so much.
