This is a set of 4 fender liners, skirts, aprons, splash guards, or "splash seals" for your 2007-2020 Toyota Tundra & Sequoia. These are the rubber aprons or skirts that go between the back of the wheel well and the frame before and after the shocks behind your front wheels. There are 4 on every Tundra & Sequoia. On each side, there is one of these guards in front of and behind the shock. It is important to have all 4 of them in place as they are critical for keeping splashing water and debris out of the engine compartment and thus alternator, etc. We proudly manufacture these locally in Colorado, so they are 100% Made In USA, and we sell them for half the price of the dealer with higher quality rubber. Toyota sells these from $45-$65 each. Buy from us, get higher quality rubber, and support a made in USA small business. We sell each piece individually, offer a set of all 4, and include the clips and a clip removal tool with every order for FREE! (Dealer charges up to $5.50 each. Ouch.) Note: Rear right and left of these are the same part on 2007-2019 Tundras. Just order two, or two come in our set. Note: Replaces OEM part numbers: 53737-0C030, 53736-0C030, and 53739-0C020 on all models. These parts fit: 2007 Tundra, 2008 Tundra, 2009 Tundra, 2010 Tundra, 2011 Tundra, 2012 Tundra, 2013 Tundra, 2014 Tundra, 2015 Tundra, 2016 Tundra, 2017 Tundra, 2018 Tundra, 2019 Tundra, 2020 Tundra.
