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.

AEV Ram Concept is an aftermarket Power Wagon

American Expedition Vehicles showed off its simply named Ram Concept at this year's SEMA Show in Las Vegas. Starting with a 2014 Ram 2500 Crew Cab and a 6.7-liter Cummins turbodiesel, the Michigan-based team at AEV, which has made a name for itself building ultra-capable Jeeps, promises that this Ram is a "complete vehicle package."
As part of that "complete vehicle package," the AEV Ram has been lifted three inches in front and two in the back, in order to give it a level ride. The suspension tweaks don't end there, though, as the geometry has been changed and custom shocks fitted, while AEV modified the truck's steering to make it more precise.
It rides on massive BF Goodrich rubber and 17-inch AEV wheels. The front bumper is from stamped steel and can accommodate a winch and auxiliary lights, as needed. Other body mods include flared fenders that can handle the larger rubber.

CEO Sergio Marchionne curses FCA spokesman for emissions cheating denial

WASHINGTON — Fiat Chrysler Chief Executive Officer Sergio Marchionne reprimanded the company's top U.S. spokesman for issuing press releases about Fiat's vehicle emissions practices days after Volkswagen's disclosure in September 2015 that the German automaker had used illegal software to evade emissions tests, documents released Monday show. Lawyers suing Fiat Chrysler Automobiles in a securities case filed excerpts of an email from Marchionne to Gualberto Ranieri, then the company's U.S. spokesman, in a filing in federal court in New York criticizing him for saying that the company does not use defeat devices. "Are you out of your goddam mind?" Marchionne wrote in an email on Sept. 22, 2015, adding that Ranieri should be fired and calling his actions "utterly stupid and unconscionable." The company said in a statement on Monday it was "understandable that our CEO would have a forceful response to any employee who would opine on such a significant and complex matter, without the matter having been fully reviewed through its appropriate channels." The statement added that Ranieri's comments came just days after VW's emissions issue became public "and before a comprehensive internal review and discussions with component suppliers was possible." Fiat Chrysler was sued in 2015 along with Marchionne and other executives over claims it defrauded shareholders by overstating its ability to comply with vehicle safety laws. An amended version of the complaint filed in 2017 added claims about its compliance with emissions laws. The shareholders accused the defendants of inflating Fiat Chrysler's share price by hundreds of millions of dollars from October 2014 to October 2015 by downplaying safety concerns. They said the shortcomings materialized in 2015 when the automaker was fined $175 million by the National Highway Traffic Safety Administration, and took a roughly $670 million charge for recalls. Plaintiffs filed the excerpts seeking approval to take up to 40 additional depositions, including Marchionne's. The U.S. Justice Department sued Fiat Chrysler in May 2017, accusing it of illegally using software to bypass emission controls in 104,000 diesel vehicles sold since 2014. Fiat Chrysler has held numerous rounds of settlement talks with the Justice Department and California Air Resources Board to settle the civil suit, including talks as recently as earlier this month. It faces a separate criminal probe into the matter.
