Fits perfectly just like the factory ones that came with my truck. Bottom two go in real easy, top two controls are a little tricky. You have to take the air bag out to get more slack in the wires. Taking out and reinstalling all 4 controls took about 10 minutes. If you have troubles youtube has videos.

Only too about 45 minutes to have my F150 power door locks working like new. The price for the new actuators was remarkably great.

Simple install and on the 2006 Monte Carlo it was installed it did not require a relearn procedure. Way to early to give it a higher rating due to the longevity in which it has been in the vehicle. Less than $80 for the part compared to what a dealership would charge for there OEM part plus a shop rate it pays to diy these simple installs yourself or ask a friend to help that has mechanical abilities.

Only needed the passenger side, but got both sides for a great price. Installed the passenger side and it is working, so I'm very happy to have the lock working again. Will order again if needed!

The price for both the left and right Actuator was the same price if I had just purchased one.

Appear to be made well, fit perfectly, 10 year warranty and the car has been restored back to its original height so it doesn't scrape on every driveway entrance. The only thing I find funny is that if you order the front set and the rear set individually vs ordering the complete set of 4 under one part number it's more money to order the set of four together. You would think it would be just the opposite, that you would get a discount for ordering four strut set.

I recievered door actuaters sooner than expected' I installed both actuaters and they solved my problem, both of my old actuaters were not working for about three years, it feels good to lock doors with the remote. The new actuaters worked perfect.
