What Year Toyota Tundra Parts are Interchangeable?

What Year Toyota Tundra Parts are Interchangeable?

Toyota Tundra is a full-size pickup truck sold in the US since 2000. There have been 2 generations in use since its introduction up to 2021, and the 3rd generation is coming out in 2022.

What Year Toyota Tundra Parts are Interchangeable? According to our experience and customer reviews, you can interchange different parts of Toyota Tundra from 2000 to 2006. The 2nd generation Toyota Tundra, 2007-2013 models, have the same design, and most common parts are interchangeable. From 2014 to 2021, Tundra has a redesigned look within the 2nd generation, and you can swap their parts.

It is popular amongst the public because of its durable built to ensure safety and reliability.

Most of the time, you have come across a situation where your Toyota Tundra truck has undergone a crash or mishap, any major parts failure, or you want to upgrade it according to your requirement. 


Toyota Tundra, 2000-2006 year variants, have 3.7L and 4.0L V6 engines and 4.7L V8 engine in three power ratings.

However, you can only interchange 3.7L in 2000-2004 models while the rest of the 1st generation models have 4.0L V6 engines. The 4.7L V8 is compatible with respective model year trucks having the same transmission.

To replace them with 4.0L and 4.7L engines in the 2nd generation from 2007-2013 variants, you will also need to change the ECU because they have variable valve timing technology.

Moreover, I recommend changing the wiring for cam adjusters and intake valves to make them useable with the new ECU.

2007 onwards models in 2nd generation also have a powerful 5.7L V8 engine with dual VVT technology while 4.6L V8 replaced the 4.7L in earlier vehicles.

Therefore, they are compatible with their respective model years by doing minor modifications regarding upgrades by Toyota in subsequent years.

Transmission system

2000-2004 Toyota Tundras have manual 5-speed and automatic 4-speed transmission systems.

For the 2005-2006 models, there are 6-speed manual and 5-speed automatic transmission systems.

However, you cannot use them in old variants without any changes because of new sensors and improved electronics components.

A 6-speed automatic transmission AB60E is interchangeable in the 2007 Tundra and its 4X4 version AB60F with 5.7L V8 engine in the same model year.

Some people have experienced problems in the smooth shifting of gears in automatic transmissions in 2nd generation models and want to swap with 6-speed manual transmission.

There is no feasible option for such modification as it requires a lot of money to change the computer programming and other changes to make it work.

Therefore, from 2010 till the end of the 2nd generation, all trucks with 4.6L V8 engines have A760E 6-speed automatic transmission, and you can replace them with the same model years.

Suspension system

Most Toyota Tundra suspension parts on 2007 and onwards models are not interchangeable with 2006 models because of generation change.

By remodeling, the manufacturer makes design changes, resulting in changes in the dimensions of parts. However, you can ensure parts’ interchangeability by measuring the shock length, mounting bolts diameter, and position.

For example, front suspension differs in the 1st and 2nd generation due to distinct bolt patterns and top clearances.

Moreover, the 2015 model and onwards with TRD pro package upgraded its suspension systems with extra support, extended shocks, and coil springs for off-road applications.

Computer module

ECU/PCM malfunctioning is frequent due to damage of electronic components due to moisture or water entering the module.

Therefore, the only option is replacing the engine computer for its proper functioning and activation of all safety features, including ABS and airbags. You will most probably find the one in the junkyard or online stores.

ECU/PCM modules are compatible with trucks of that particular model year having the same type of engine, drive configuration, and transmission system.

For example, if you have a 2010 truck with a 5.7L flex engine and 4X4 drive, you should interchange it with the ECU from the truck with the same options.

Despite replacing the module with having matching part numbers and other specifications, you will always need to reflash its program to feed your truck’s VIN and other parameters.

Sometimes, even it disables a few features and requires modifications in wiring harnesses and other instrumentation.

Interior parts

The interior of the truck contains parts including head unit, seats, dash console, and flooring that remain unchanged in a generation.

Therefore, you can replace parts between model years 2000-2006, 2007-2013, and 2014-2021. In addition, there can be slight modifications in adjacent years’ trucks due to minor upgrades every year to launch a new model of their vehicles.

For example, 2000-2005 variants have interchangeable buckets or bench seats. However, you will take into consideration the change in any electrical wiring.

Moreover, 2007-2013 year vehicles have Bluetooth feature and large center console, therefore, not compatible with old vehicles.

2014-2021 Toyota Tundra has an updated interior with a large infotainment display, new seats, additional airbags, and an upgraded dashboard and instrumentation cluster. Therefore, you can only replace interior parts in these model years with a few skillful modifications.

Body parts

Bumpers, grille, fenders, headlights, doors, mirrors, wheels, and windows are major body parts interchangeable between various models.

For example, front bumpers within a generation of trucks have a matching design, size, and mounting brackets.

However, they require a bit of modification to install them properly. Furthermore, rear bumpers on 2003-2006 models are the same in all cab configurations, and you can swap them.

Similarly, front doors on all three body shapes are of the same shape and size. The front fenders, hood, and grille are interchangeable between the 2014-2021 models.

Rear windows are different in regular and double cabs from Crewmax design with power option.

Moreover, windows with auto up/down switches in higher trim levels like Platinum are not compatible with the lower trim level SR5.

However, grille designs are interchangeable with higher trim levels if you want to improve the look of your pickup truck.

Finally, wheels are compatible between various models if they have the same size, bolt pattern, offset, and backspacing. 


Parts of the drivetrain are axles, driveshaft, joints, and differential. A rear axle or differential has a gear ratio that should match the replacing part.

Moreover, it also has fitting to cater to the suspension mounts. Therefore, you can interchange them between different model years having the same gear ratio and modifying mounts.

It is mandatory to change the speed sensors; otherwise, you will not get good results with automatic transmission.

Measure the length of the driveshaft of your vehicle and find one with the same size and other fitting arrangements.

Are Toyota Tundra Truck beds interchangeable?

1st generation Toyota Tundra has 2 cab configurations, including access cab with 6.6-ft regular bed and regular cab with 6.6-ft and 8.1-ft bed options.

In the 2003 model, there is a third double cab truck with a 6.6-ft bed. 2nd generation models have Regular and Double cab options with 2-bed lengths of 6.6-ft and 8.1-ft. While the third Crewmax body has only a short bed choice with a size of 5.6-ft.

Despite the body styling and cab configurations changes, truck bed dimensions are the same as already mentioned for all Tundra model years.

Therefore, you can swap them with the same size truck beds. The only thing you need to take care of is the location of the fuel filler cap and the tailgate design.

It can have a slightly different position. Moreover, 2003 access cab models have side step beds, but that has nothing to do with truck bed size or its installation.

Are there any interchangeable parts between Toyota Tundra, Toyota Tacoma, and T100 trucks?

1st generation Toyota Tundra has matching design and specifications with Toyota Tacoma and T100 trucks, including engine and other parts.

Therefore, you can interchange those specific parts by modifying them according to the requirement.

2nd generation models from 2007-2013 have body styling, including grille design and bumpers similar to Tacoma trucks. Therefore, you can swap them by taking appropriate measurements.
