2020 Ram 1500 4x4 Suspension Deep Dive

What is taking everyone so long? That’s what I continually ask myself each time yet another all-new full-size pickup comes out with leaf spring rear suspension. Meanwhile, this 2020 Ram 1500 pickup represents a dozen years since coil spring rear suspension debuted when its prior generation was still being called a Dodge Ram 1500. Ford, Chevrolet, Toyota and Nissan introduced full redesigns of their pickups well after Ram proved that coil springs were the way to go, and yet leaf springs persist with the competition. IÂ’m not just popping off, here. In the 1990s I used to specialize in pickup truck suspension tuning for the Toyota Technical Center. Leaf springs are crude and loaded with compromises, but thatÂ’s all that truck design engineers ever gave us to work with. I was instantly all-in on RamÂ’s move to rear coils after the first few miles of driving a 2009 Ram 1500 pickup. Empty-bed ride comfort and handling were on another level, but it could still tow and haul. In fact, towing stability proved to be frankly incredible on the normally-treacherous downhill leg of my winding tow test grade. I fully expected everyone would copy it immediately. But they didnÂ’t. Others may have doubted the payload aspects. Ram never did. It soon doubled down and put coils under the back of its 2014 2500-series trucks. IÂ’ve developed other theories that seek to explain why no one followed their lead, but theyÂ’re not worth dredging up because I think the dominoes will soon begin to fall. Spy photos suggest that the next Toyota Tundra will switch to coils, and there are rumors that the Ford Raptor is going that way. ThatÂ’s not much of a stretch because the Ranger Raptor (only available outside the U.S.) already has coil spring rear suspension. WhatÂ’s the big deal? LetÂ’s take a look at the underside of a 2020 Ram 1500 Laramie 4x4, the second iteration of the Ram 1500 to employ coil spring rear suspension.   As it has for some time, the front end of the Ram 1500 rides on double wishbone suspension. The truck employs a high-mount upper wishbone (yellow arrow) that positions the upper ball joint up behind the tire sidewall instead of inside the wheelÂ’s barrel. This layout offers improved steering geometry and reduced stress in the upper ball joint, the upper control arm and its mounting points.   Coil-over spring/shock assemblies (green) come standard on all 2019+ (fifth-generation) Ram 1500 pickups whether they have four-wheel drive or not.

Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.

2021 Ram TRX to be revealed this summer

The wait for the 2021 Ram TRX will soon be over, FCA confirmed Thursday with a social media teaser. The much-anticipated, Hellcat-powered Raptor slayer will be revealed this summer.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Ram teased the unveiling on Twitter with a short video of the truck kicking up a massive desert dust cloud overlaid with the TRX badge and the caption, "It’s not a mirage." Make sure you enable sound, because the clip has audio, and you can hear the beating heart of the TRX — the same 6.2-liter supercharged V8 that powers FCA's Dodge Hellcat and Jeep Trackhawk models.  The engine sound in the clip lends credibility to a previous spy video purporting to show a group of TRX prototypes testing in Michigan's Silver Lake Sand Dunes.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. The link in the tweet leads to a microsite which replays the same short clip but offers no additional information, which tracks with the slow-drip approach Ram has taken with teasing out its new truck. Much of what we know (or believe to be true) has come from unconfirmed sources and spy shots, but Ram has acknowledged that the Hellcat powerplant will make more than 700 horsepower, rather than the 500-some-odd figure originally expected.  From the above shots, we can tell the TRX will sport bulging box flares (a la Raptor) front and rear. The hood appears to be equally bulging, good for highlighting the supercharged V8 underneath. The front bumper is similar to that of the Ram 1500 Rebel's with more raised sections in front of the tires to provide more clearance. Ram 1500 TRX View 18 Photos We get a solid look under the body, too. Still present are the extra beefy suspension control arms front and rear. Skid plates seem to line the whole underside down the middle. The tires were Goodyear Wrangler all-terrains, though it was difficult to make out the actual size. Previous spy photos have revealed remote-reservoir shocks. The wheels at each end are six-lug units, so it seems Ram isn't playing with a heavy-duty axle like a previous prototype suggested. Whatever the case may be, we should be no more than a couple of months away from getting the official details on Ram's new Raptor competitor.  Related Video:
