Lift Supports Depot Toyota Tundra Rear Tailgate Lift Support 2007–2021 — Driver-Side Direct-Fit (Replaces 66140-0C010)

One replacement lift support designed to fit the rear tailgate of Toyota Tundra models (2007–2021), replacing OEM 66140-0C010 for reliable, smooth tailgate operation.

When your Tundra’s tailgate no longer holds open or opens unevenly, replacing the single driver-side rear lift support restores controlled, safe movement. This direct-fit strut from Lift Supports Depot matches the OEM mount spacing and provides the right length and force to support the tailgate behind the driver’s-side rear lights. It’s intended as a straightforward, budget-conscious replacement that installs quickly with common tools.

How will this lift support affect my tailgate’s performance?

Installing the correct lift support returns the tailgate to steady, dampened motion so it opens and closes without sudden drops or slamming. The gas-charged design supplies consistent pressure across the travel range to hold the tailgate at various positions.

• Restores steady open-hold behavior and easier closing.
• Reduces wear on tailgate hinges and cables by stabilizing movement.
• Matches OEM mounting points for correct leverage and alignment.

Is this an exact replacement for OEM number 66140-0C010?

Yes — this lift support is manufactured to replace OEM 66140-0C010 and multiple equivalent part numbers listed by Toyota. It’s intended as a direct fit so no custom modification is required for compatible vehicles.

• Center-to-center extended length: 16.8 inches for correct geometry.
• Compatible with listed OEM numbers like 050483, 050722, 673533, and PM17066.
• Single-piece strut built to match factory mounting orientation behind the driver-side rear light.

How difficult is installation and what tools do I need?

Installation is designed to be quick and user-friendly; most owners can swap the strut in minutes. The unit uses common ball-stud mounts and simply snaps on after the old support is removed.

• Typical tools: a small flat screwdriver or pliers to release retaining clips.
• No special presses or spring compressors required — push-on ball sockets simplify the job.
• Lift one side of the tailgate slightly for support while swapping the strut to avoid strain.

What materials and quality should I expect from Lift Supports Depot?

Lift Supports Depot builds this strut from durable materials chosen for automotive use, combining a corrosion-resistant finish with gas pressure technology to deliver long service life. The unit is engineered for repeated cycles in exterior vehicle conditions.

• Corrosion-resistant coating to withstand weather exposure.
