Bilstein33253190 Shock Absorber

Installed these shocks onto the rear of my 2017 F-150 Lariat 4x4 at factory ride height. Installation took about 10 minutes total for both sides, and they can (and should!) be installed with the truck on the ground, no lift or jack required. Tools required include a ratchet, 15mm Socket, an 18mm Wrench, and (ideally) a torque wrench.I would highly recommend replacing the factory bolts and nuts with new ones, regardless of visual condition, as the factory nuts are of the self-locking variety and thus not designed for reuse.Regarding performance, the factory shocks on the F-150 are not ideal and in some cases potentially dangerous. This is especially noteworthy when hauling near the payload capacity, towing heavy loads, or when the rear suspension encounters some type of shock that needs to be damped (An example of which would be how the rear end gets loose driving over speed humps or railroad tracks).These shocks greatly improve the rear end stability of the vehicle, and handling is much more predictable and improved in all of the aforementioned scenarios. And while shocks are not an adequate replacement for an anti-roll bar, they do improve cornering stability in a noteworthy manner.While the shocks improve handling performance, they do impact the ride quality SLIGHTLY. Whether this is perceived as a negative or positive impact is likely down to the preferences of the person driving the vehicle, but it does result in the rear suspension feeling a little less like a cloud (Vibrations are damped faster than stock), and slightly more firm. Again, this difference is noticeable but not significant. At the end of the day, the truck still will still ride like a high-quality truck. We're just talking about a shock absorber change, so don't expect a small change to cause the truck to feel like it now has independent rear suspension.Overall, In my opinion, these shocks are one of the best upgrades for the money that you can make to your Ford truck as long as you know what to expect out of them. And you can install them with simple hand tools in your driveway in a couple of minutes.

Installed these Bilstein 5100's on the rear of my 2018 F-150 Super Crew a few days ago. There is a noticeable difference in the trucks ride that I experienced immediately. The rear end on my truck has been what I can only describe as "twitchy" since I bought it 2 months ago. Bumps were not absorbed and the rear end was always feeling like it was not planted over bumps. After the Bilstein installation, the rear end now absorbs small bumps so I don't feel them, the wheels stay planted on medium bumps, and on large holes and speed bumps the rear end still jumps off the ground (but not as much as it used to). I would definitely advise any new F-150 owner to change to these right away and throw away the crap that came on the truck from the factory.When I pulled off the factory shocks, I tested them for compression and rebound...much worse than the 5100's. The factory shocks had some gas in them, but not much. Also, the travel was not smooth like the 5100's. After compressing them a few times, I was not surprised why the rear end was so twitchy from the factory. I can't speak to the longevity of the 5100's, but my initial impression is that they are definitely worth the $150 investment.Installation took about 30 minutes. No need to jack up the truck, install can be performed with truck at ride height on the ground. A couple of metric wrenches, a torque wrench, a small pry bar, and blue LocTite is all you need to change the 2 rear shocks. Torque spec for my truck was 66 ft. pd. for both top and bottom bolts. The upper nut on the drivers side was a little weird. It had no place for a wrench...instead it has a large tab welded on that hit the frame and kept it from spinning when I loosened the bolt...whatever works, not sure why Ford decided to do this on 1 of 4 nuts.UPDATE: Have been driving on these 2 rear Bilstein's for about 3 weeks now. It seems to me that they are "breaking in" a bit. Ride seems even better than when I first installed them. Almost makes me sad that I don't have the money to replace the front shocks as they feel like garbage compared to the rears. Bumps are no longer something I try to avoid...just plow right on through! I put these on a 24 month lease truck and I think it was $150 well spent.UPDATE: Moved these 5100's to a 2019 F150 with no issues. Been driving on them for over 10,000 miles so far between 2 trucks with zero problems. At my next lease change, I expect to move them again. Great investment!

As you would expect, installing these is pretty simple. The ride quality is incredible. I put them on a 2016 F150. I had the rear tire hop going around curves. These shocks completely removed that. The truck drives so much better. It’s a softer ride, but still drives like a truck. Just nicer. I’ll be getting the front struts soon.

This was a good investment for my 18 F150, even though my truck only has 45K miles there was a difference from the factory shocks. I even pull/push tested the oem and bilstein shocks and a good difference between them, bilsteins being stronger. Install was easy, 15mm bolt and 18mm nut on each one, (driver side upper had a nut with a small bracket to keep it from turning so didn't really need a wrench on it at first) took about 25 minutes and after a test drive I am happy, rear end stays planted better, takes bumps better and feels more stable! Now on to do the bilstein fronts and level the truck!
