Just put a pair of Bilstein 4600's on the rear of my 2016 screw XLT. It has made a tremendous difference in how the whole truck handles. In the past I've had several experiences of the backend "stepping out" over uneven/broken pavement. The first time it happened I had my wife, 2 kids and dog aboard and everyone wondered what the hell was going on.
My truck is now very composed with a slightly firmer feel to it much like my 2013 Tacoma TRD Sport felt like.
Took 15 minutes to put on in the driveway without removing rear wheels. You'll need a 15mm and an 18mm socket or wrench. Nuts need to be torqued to 67 ft/lbs.

Even my wife likes the difference, as she said the truck use to feel like (in certain situations) the 1984 Oldsmobile Delta 98 Royale she drove when she was younger

Thanks for your write up Billy. I'd like to order a set. No issues with installation or anything that I should look out for?

Cheers,
Bryan

I put 5100s on the back of mine. Wish I had gone with 4600s. I will be putting 4600s on the front in the near future.

Whats the difference between the 2?

5100's are for meant for lifts and 4600 for stock height/non lift.

Been wondering about this. I have no plans to lift, and want to get rid of those awful factory hoppers. I was accelerating on the onramp tonight hit a bump and the rear end came off the ground squealing the tires.

Adding 4600 to my list. Was going to get 5100's but the lift part was questionable.

To an extent, that is true. The front 5100s are adjustable and do allow you to lift the front a bit. But the rears do not provide any lift. I believe the main difference is that the 5100s are more heavy duty, and more capable of off road driving. This translates to a little stiffer ride on the road. Some people like that, others don't.

The only problem you may have during the installation is compressing the shock to place it on the axle hanger. When I mounted the shock I did the top first (frame mount) and then the bottom (axle mount). You have to compress the shock about 4 inches to get it onto the axle mount hanger. If you are a younger person it probably will not cause much strain. If you are older you may want a helper ! I'm middle aged and I got it done with a little bit of grunting

I finally got around to replacing the rear shocks with the 4600's. No more teeth chattering over the bumpy stuff, smoother ride in the back-end and works well combined with the Hellwig sway bar for better handling. Now I really notice the choppy front end ride and I'll will be replacing those shocks with the 4600's within the new few weeks.

Highly recommended if you're keeping your truck at stock height and hate the ride quality.

Thanks Billy for the heads up on these.

I read many posts concerning inferior OEM Ford shocks on their F150s. I only have 2000 miles on my 2017 XLT F4 Screw. I have not experienced any of the described symptoms. Hopping etc. This truck rides and handles very well, considering it probably has heavier duty shocks because it is a 4X4. Ford must be reading this forum.
