- REDUCES SAG UNDER LOAD -- Ideal for occasionally hauling or towing varying loads; heavy gauge, calibrated coil spring reduces sag when loaded up to 1,200 lbs. (capacity limited by suspension, tires and transmission; see owner's manual)
- EXCEPTIONAL HANDLING -- Tuned specifically for each application, full-displaced valving automatically adjusts to road extremes to provide ride consistency
- CONSISTENT RIDE -- OE all-weather fluid contains special modifiers to handle extreme temperatures and PTFE-banded piston helps reduce friction between the piston and pressure tube to enhance responsiveness to changing road surfaces
- LONGER SERVICE LIFE -- Self-lubricating fluid seal retains gas and reduces excessive friction against the piston rod to help reduce premature wear while heavy-duty nitrocarburized rod delivers long life
- IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
Description
Ideal for light trucks that that tow or carry varying loads, Monroe load adjusting shocks include a heavy gauge calibrated spring that adjusts to road and weight conditions to provide extra control when operating conditions get more demanding.

I had installed a set of these on my 99 ram and had them on there for about 50k miles before the engine finally went and I had to buy a replacement truck. I bought a 2013 f150 xl single cab long bed (I couldn’t afford an f250 so let’s get that out of the way). While it has the towing package, it doesn’t have the max trailering package. Meaning it doesn’t have the heavier duty suspension set up. I haul materials to job sites every day, sometimes including over 2,000 pounds worth of shingles. The truck is only rated at about 1,800 lbs of payload, and it certainly couldn’t keep up with my half ton ram with even 1000 pounds loaded in the bed. The squat was insane. 1,200 pounds was the true maximum. Even though it says 1800 pounds on the door. And towing a trailer was ridiculous. Even a small 20 foot unloaded wood bottom trailer would sink the rear end. So as soon as I could, I installed these. They’re cheap, they’re invaluable. The ride is much more stable loaded and unloaded than it was before. Loaded even more so. I’m not swaying all over the road like I was before. It also seems to be helping with my front tire wear. The new tires aren’t wearing prematurely like the last ones did. It’s much more stable on wet roads!!! It’s much more stable on washboard roads too. With those extra springs it really pushes those back tires back down more quickly than standard shocks do. There’s a road near my house that has a curb with cobblestone bumps. Without these hitting those bumps would toss the back end around. Surely only a few inches side to side, but it felt like a few feet side to side every time I would hit them. These shock put an end to that. The ride is better and worse. These shocks better absorb large bumps, but they’re stiffer on small bumps. I feel cracks in the highway now more than I used to, but when I hit a pothole it’s more cushioned than it used to be. So it’s a trade off. It’s definitely smoother on the highway without a doubt. It did raise the rear end of my truck considerably for the first couple of weeks until they really broke in. It raised the rear about 3-4 inches, however my old shocks were so blown out, and surely the leaf springs were tired enough that they were probably sagging a couple inches to begin with. After about a month or so it settled to a normal ride height. Even with the bed of other f150s I park next to. So about 2 inches taller than it was with the old shocks, 2 inches shorter than it was when I first put the new shocks on. They installed fairly easily. I did have to remove both rear shocks first, that way the axle had enough flex to do one side at a time. These are much longer than the old shocks. I used my tall bottle jack and tall jack stand, raising the truck as far as the bottle jack would take it, then putting the jack stand under it, then lowering the bottle jack, spinning the lift screw as high as It would go, jacking it up more, then of course raising the jack stand higher to support it. This allowed the first side to easily slip in and bolt right up. The other side, at least on my dodge was much trickier, but easier on this ford. I did have the press the bushing on the second one in better with a pair of channel locks. It wasn’t quite right and wouldn’t fit into the shackle to slide the bolt in. It’s nothing major. Just be aware it may be an issue.

Installed on a 2014 F 150 I waited to post my review for wanting to see how well they hold up. I couldn't be happier with how well the shocks have been. I pull a trailer daily and not only did these raise my ride when I have a heavy load on but they helped with handling a lot more than I thought they would. For what they cost and for there performance I believe you would be hard pressed to find any better will definitely purchase them again if I am in need of replacement. Great fit and easy replacement took me about an hour to an hour and half.

NOTE: This contains 2 SHOCKS, you only need to add one of this to your cart to get 2 shocks, they are SOLD IN PAIRS. That being said, I installed these on my 05 f150 to replace the OEM shocks at 107k miles. Regular unloaded ride did not change much, except for better on bumpy roads, but not any more harsh. I'd say more like the OEM ride would have been when new. Now where these excel is when you drop a trailer on the back. NO SAG at all! My trailer used to "level" my truck when hooked up, now when the trailer is on the back of the truck, you can't even tell, NO MORE SAG. Also, when towing, the trailer no longer makes the back of the pickup bounce when going over bumps, its soo solid you'd swear the trailer wasn't even back there. Easy to install, don't even need to take the tires off. Just place jack under the FRAME of the truck in the rear (do not put jack under the rear diff!!). Unbolt bottom shock bolt, then the top, and remove old shock. Bolt top of new shock in, but not tight yet. Now jack the truck up so the suspension unloads (i.e. hangs down on the side you are working on). Jack it up until the bottom shock bolt hole lines up. Tighten both top and bottom, then let truck down. Rinse and repeat on other side, then enjoy the ride!

These shocks are for a ford f150 pickup I believe but read in jeep forum that these shocks are the correct length for a jeep wk with 2" lifts installed. The quality is great and the operation is great too. FYI for the lifted jeep wk owners. The jeep wk driver side rear was a real pain. These shocks are so long and with the spring built on, it is almost impossible to compress to get in and install. Even with axle drooped as far down as possible. Will unbolt the rear upper control on the driver side next time to allow the axle to drop further because it hits gas tank if not unbolted. The ride height is higher in the back with these shocks. Don't know by how much but you can see a slight rake. The ride quality is still up in the air. Hauling a load is smooth as silk. Very responsive shocks but when unloaded, the feel to me is like a "hop" in the back end when hitting bumps like train tracks. If your hauling all the time, these would work great but if you do a lot of commuting unloaded then I would buy something else that are not for hauling. Time will tell if these shocks will sag a little and be less "hoppy".

First, I like shock and ride improvement. However, they are a pain to install. These shocks are long and too stiff to install without mechanical assistance. Tried a spring compressor; no joy. Ended up using a scissors jack to compress and position the lower eyelet.
