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.

Ram recalling 65k trucks for rear-axle heat treating

A problem with the rear axle has promoted Fiat Chrysler Automobiles to recall a selection of Ram trucks. The campaign affects 2015-16 Ram 1500 series trucks – specifically those manufactured between June 17 and September 28, 2015. All told, that amounts to over 65,760 units across the United States. The issue stems, according to the statements below, from the rear axle shaft. Some of those trucks may have not had those axle shafts properly heat-treated, which could cause them to fracture and separate from the wheel. And that, it should go without saying, could lead to a crash. FCA states that most of the vehicles in question are in dealer hands, but while the manufacturer says it is aware of one accident to have resulted from the issue, no injuries have been reported. The owners of the affected vehicles will be notified to bring their trucks in to their local dealership to have them inspected. If necessary, the dealership with replace the rear axle assembly. This recall follows three prior (but unrelated) ones, also issued for Ram pickups, that between them affected well over a million units.

The affected vehicles may have been built with rear axles that were incorrectly heat treated. CONSEQUENCE: If the rear axle shaft was not properly heated treated, it may fracture and a wheel separation could occur, increasing the risk of a crash. REMEDY: Chrysler will notify owners, and dealers will inspect the vehicles and replace the axle assemblies, as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R59. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. ### Statement: Heat-treating October 27, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 65,760 U.S.-market trucks – most of which are in dealer hands – to inspect and replace, as required, their rear axle shafts or rear axles.

2021 Ram 1500 TRX vs. 2020 Ford F-150 Raptor | How they compare on paper

Now that the 2021 Ram 1500 TRX has debuted, it’s time to pit the off-road truck against its only true competitor: the Ford F-150 Raptor. Ford has left us in a weird spot with the Raptor, though. ItÂ’s currently in-between models, as the regular 2021 F-150 is out, but the 2021 Raptor hasnÂ’t been announced yet. Since the F-150 is moving into a totally new generation for 2021, the Raptor is bound to be much different a year (or even months) from now than it is today. Regardless, the Raptor as it stands today is still a worthy adversary for RamÂ’s new super truck. The TRX is much more expensive than the Raptor at its base level, but you can spec out a Raptor that comes close to the TRXÂ’s base price. That said, a TRX can crest $90,000. Neither of these trucks are cheap. So, letÂ’s get to the all-important specs and figures. The chart is below. WeÂ’ll note that Ford offers the Raptor in SuperCab and SuperCrew forms, but the TRX is only offered in Crew Cab size. For comparisonÂ’s sake, weÂ’ve chosen to provide figures for the SuperCrew that closely aligns with the Ram Crew Cab.   Powertrain ItÂ’s fairly obvious who has the advantage here. FCA just keeps spreading the Hellcat love around, and Ram is the latest brand to get a taste. The TRX has a whopping 252 horsepower and 140 pound-foot advantage over the Raptor. ItÂ’s also far quicker to 60 mph than the Ford. Nothing in the truck realm can touch the TRX in a straight line. Plus, the supercharged V8 produces much better noises than the F-150 Raptor and its boosted V6 is capable of.  Fuel economy for the TRX isnÂ’t out yet, but expect it to be even more horrendous than the RaptorÂ’s. If efficiency is even remotely important to you, neither of these trucks should be on your shortlist.  Both these trucks come with four-wheel-drive standard, and they both have a number of drive modes that alter the powertrainÂ’s characteristics depending on the terrain. Baja mode transforms the trucks into the desert runners that they both are at heart, but theyÂ’re plenty capable of crawling around rocks, too. We wonÂ’t know for certain which is best at specific tasks until we can get them both on (or off) equal ground. Suspension / off-roading capability The specs are freakishly similar when we compare ground clearance, approach/departure angles and water fording, but these two trucks use different strategies to get there.
