This is a set of all four fender liners, skirts, aprons, splash guards, or "splash shields" that fit your 2000-2006 Toyota Tundra or your 2001-2007 Toyota Sequoia. See our other listings for many other vehicles. These are rubber aprons 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 and 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. Note: Replaces OEM part numbers: 53737-0C010, 53736-0C010, 53739-0C010, 53738-0C010, 537370C010, 537360C010, 537390C010, and/or 537380C010 on all models.
