Left and right tailgate hinges for 2007-2021 Tundra
This two-piece replacement set covers the left and right tailgate hinge positions on a 2007-2021 Toyota Tundra. It includes two different hinge assemblies: a pivot housing with a curved arm and ball stud, plus a separate mounting plate with a raised, rounded rectangular opening.
The arm assembly has a silver aluminum bushing fitted at its hinge end. Each mounting plate has two bolt holes. Compare both assemblies with the parts on your truck before ordering, especially the hinge-end profile and the arm arrangement.
Check both sides against the reference numbers
The listed references are 66102-0C021 for the left-hand position and 66101-0C020 for the right-hand position. Toyota identifies these numbers as tailgate hinge sub-assemblies. Use them to check the hinge configuration on your vehicle; this is an aftermarket replacement set.
The two pieces have different shapes. Match each piece to its corresponding location rather than treating them as interchangeable left and right copies. Check the mounting-hole spacing and the mating tailgate opening as well as the reference numbers.
