Description

The Monroe Suspension Shock Absorber and Coil Spring Assembly is an essential vehicle suspension part engineered for drivers who demand reliability and performance from their trucks. Specifically designed for light trucks that tow or carry varying loads, this rear shock absorber integrates heavy-duty, calibrated coil springs that automatically adjust to changing road and weight conditions. The robust construction reduces sag load by supporting up to 1,200 lbs, depending on your vehicle’s suspension, tires, and transmission. With every journey, you can count on consistent ride quality and added control, even when operating conditions become more challenging or unpredictable. This truck shock assembly is tuned for each specific application, utilizing full- displaced valving to respond precisely to road extremes, ensuring ride consistency regardless of the terrain. The OE all-weather fluid contains special modifiers to handle temperature extremes, and a PTFE-banded piston reduces friction between the piston and pressure tube for better responsiveness. The nitrogen gas-charge helps the shock absorber maintain optimal tire-to-road contact, minimizing aeration and shock fade, which translates to improved handling and ride stability. Whether you are seeking shock absorber replacements for daily use or for tackling demanding loads, this assembly is built to outperform conventional options. As one of the world’s leading designers, manufacturers, and marketers of automotive products for aftermarket customers, what DRiV makes matters. How we show up and compete in the marketplace matters. Our business performance matters. But the thing that matters most is what we stand for together—what we value. Our values include Radical Candor, Simplify, Organizational Velocity, Tenacious Execution, and Win. With a dependable history, you can count on DRiV to deliver what matters.

I just installed these after I noticed the bushings on my oem shocks were shot. Didn't even notice they were bad until riding with these new shocks. They didn't come depressed so installing them would be a little more difficult if I wasn't also replacing the blocks under the leaf springs. Definitely would loosen the u bolts and drop the whole rear diff about an inch when you install these. In the end, they fit right into place of the old shocks when I got done installing them. I do wish they came with new hardware though The ride quality was immediately improved. It doesn't sag anymore when I accelerate. Cornering feel better than before. Stop and go traffic feel better. Got rid of a shaking noise I had when I backed into a driveway with a hump (probably caused by the old shocks). I'll update this once I drive for awhile and get a better idea of how I like them but overall I think these are good quality and 100 dollar was a steal. ... show more

    • Does what they're suppose to. Good shocks
I bought these 3.5 years ago for my 2007 f150. It's an old 4x4 work truck. Im rough on it and always have a load. They performed flawlessly. I blew them out (no fault of the shock) I launched the truck over a hill pulling a trailer while chasing trespassers. That's what it took to blow them out. I definitely can tell the difference without them. Lol i will be buying the exact set again. ... show more

    • Invaluable
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. ... show more

    • Better than OEM
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. ... show more

    • Great shock
Bought these because I needed new shock first off but also to accommodate hauling of car and trailer. I can say, without hauling anything, I honestly didn’t notice a stiffer ride than what I had been told. It rode very nice and very responsive in turns. Back to hauling for it’s main purpose of purchase, they hauled the weight exceptionally well. The back didn’t sag at all and kept a great normal height. I would recommend these to anyone looking for a great ride and knowing they also can haul an extra 1200 payload with no rear sag. I did have to compress the spring to install, not a big deal, it was about 1 1/4” longer ... show more
