T1A Tailgate Support Cable for 2004-2006 Toyota Tundra - Direct-Fit OEM Replacement (Left & Right, 17.94in)

T1A tailgate support cable replaces the original Toyota parts to restore secure, stable opening and closing of your 2004–2006 Tundra tailgate.

If your Tundra’s tailgate sags, drops unevenly, or feels loose, the worn or broken support cable is often the culprit. This T1A replacement is engineered to match the Toyota OEM part numbers 65770-0C040, 65770-0C050 and related references, giving you a direct-fit option that returns the tailgate to factory-like performance without fabricating or modifying mounting points.

What exactly does this cable replace on my Tundra?

This T1A assembly is designed as a direct substitute for several Toyota OEM identifiers and restores the support function that guides the tailgate as it opens and closes. It connects at the factory anchor points and replicates the original cable length and attachment style so the tailgate moves predictably.

• Direct-fit for OEM numbers 65770-0C040 and 65770-0C050 (and compatible references).
• Pre-measured length closely matching original factory spec ~17 15/16 inches.
• Mounts to the same brackets and fasteners used on 2004–2006 Tundra models.

How durable is the T1A tailgate cable and what materials are used?

Built from high-strength metal components and designed for regular use, this replacement cable resists bending and fatigue that cause sagging or sudden failure. The construction focuses on longevity while maintaining the flexibility needed for smooth tailgate movement.

• Robust metal cable and end fittings for repeated load cycles.
• Factory-like tolerances to prevent premature wear at attachment points.
• Durability suitable for everyday driving and heavy cargo loading scenarios.

Is installation difficult and what tools will I need?

Installation is intentional simple for anyone comfortable with basic hand tools and light vehicle repair work; many owners complete the swap in under 30 minutes per side. The cable replaces the original using the same mounting holes and fasteners so no drilling or welding is required.

• Typical tools: socket set, pliers, and a screwdriver.
• Quick disconnect-style ends allow fast removal of the old cable and seating of the new one.
• Clear orientation and OE-compatible fittings minimize alignment adjustments.

Will this part fit both left and right sides of my truck?

The T1A tailgate support cable is available to replace either the driver or passenger side; choose the correct side when ordering to ensure proper fit. Both left and right assemblies mirror original Toyota placement and geometry so balance and tailgate level are restored once both sides are serviceable.

• Sold for left or right position—select side-specific listing when purchasing.
• Engineered to match the original orientation and pivot spacing.
• Works with the standard Tundra tailgate latch and hinge arrangement for 2004–2006 models.
