Standard Ignition 4WD Actuator P/N:TCA-21
Standard Ignition TCA-81 4WD actuator for the 2011-2022 Ram 1500 and other vehicles helps switch between two-wheel and four-wheel drive.
Four-wheel drive that will not engage or release, or a 4WD indicator that behaves oddly, can mean a worn actuator. These signs alone do not prove it, though, since a blown fuse is another common cause.
It fits the 2011-2022 Ram 1500, the 2006-2010 Dodge Ram 1500 and the 2019-2023 Ram 1500 Classic. Only one actuator goes on the vehicle.
Is this the 4wd actuator for a 2019 Ram 1500, part of the 2011-2022 Ram 1500 range?
Yes. Standard Ignition TCA-81 is listed for the 2011-2022 Ram 1500, which includes the 2019 model year, with no engine restriction.
Does the Standard Ignition TCA-81 work on the 2006-2010 Dodge Ram 1500?
Yes. Standard Ignition TCA-81 is a 4WD actuator listed for the 2006-2010 Dodge Ram 1500, and the years are enough to confirm fit.
Can a failed actuator be why my truck's 4WD won't engage?
Yes, a failed actuator can stop 4WD from engaging or releasing, because it carries out the shift between drive modes. A shop can test the system to confirm.
How can I tell if my 4WD actuator is damaged?
Testing a 4WD actuator needs the drivetrain running, so a shop should do it. A shop can also inspect the housing and connector for cracks or corrosion.
Is this 4WD actuator sold as a single unit?
Yes. This listing is one 4WD actuator, and the vehicle takes one.
