Tundra Generation Coverage
| Tundra Generation | Years | SC400/SC404 Confirmed? |
|---|---|---|
| 1st generation | 2000–2006 | Not confirmed — use fitment tool |
| 2nd generation | 2007–2021 | Yes |
| 3rd generation (new platform) | 2022–current | Yes — verify on fitment tool for new platform |
The 1st gen Tundra (2000–2006) predates the documented fitment range for SC400/SC404. If you have one of these trucks, use UnderCover's official fitment tool with your exact year and bed configuration before ordering.
Tundra Bed Lengths
The Tundra is available in multiple cab and bed configurations. SC400 and SC404 cover all standard bed lengths:
| Cab Config | Bed Length | Correct Codes |
|---|---|---|
| Regular Cab | 6.5 ft (long bed) | SC400 / SC404 |
| Double Cab | 6.5 ft | SC400 / SC404 |
| CrewMax | 5.5 ft (short bed) | SC400 / SC404 |
Critical Ordering Note: SC401 vs SC404
The most common ordering error for Tundra buyers is confusing SC401 with SC404 on the passenger side. Here is the breakdown:
| Code | Fits | Side | Does NOT Fit |
|---|---|---|---|
| SC400 | Tundra 2007+ AND Tacoma 2005+ | Driver (left) | — |
| SC404 | Tundra 2007+ | Passenger (right) | Tacoma passenger |
| SC401 | Tacoma 2005+ | Passenger (right) | Tundra passenger |
SC400 is shared between Tundra and Tacoma on the driver side — this is the source of the confusion. Because the driver code is shared, buyers assume the passenger code is also shared. It is not. SC404 is Tundra passenger; SC401 is Tacoma passenger. They will not fit the opposite truck.
3rd Generation Tundra (2022+)
The 2022 Tundra introduced a new platform with a twin-turbo V6 powertrain, replacing the previous V8. The body and bed architecture changed with this generation. SC400/SC404 are confirmed for the 2022+ Tundra as of October 2026, but because new platform vehicles sometimes require updated codes, verify on UnderCover's fitment tool with your exact year and bed length before ordering.
Install Notes Specific to the Tundra
Spray-in bedliner
Many Tundra trims ship with or are dealer-fitted with spray-in bedliners (LINE-X, Rhino Liner). If the liner covers the bed rail cap surface — the horizontal top face of the inner rail wall — you must remove coating at each of the six screw locations before drilling. Use a rotary tool; remove only the area at each screw diameter. This is a permanent modification to the liner. Drop-in rubber mats do not cause this issue. Full detail at the SwingCase install guide.
Tonneau cover compatibility
SC400/SC404 are compatible with most soft and hard tonneau covers on the Tundra provided 3 inches of clearance exists between the SwingCase lid and the closed cover. BakFlip (MX4, F1, G2), Extang (Solid Fold, Trifecta), and soft roll-up covers are confirmed compatible. Retrax PowertraxONE on the 2022+ CrewMax 5.5 ft bed should be measured before ordering — tight fits have been reported on short-bed crew configurations with this cover.
