2021 Ram 1500 TRX Suspension Deep Dive | Underbelly of the beast

I think we can all agree that we have been waiting for a gonzo full-size truck like the 2021 Ram 1500 TRX for a long time. After all, it has been over a decade since the Ford F-150 Raptor came out, and it was such an immediate hit that I expected its direct competitors to respond much sooner than this. We all knew something was finally brewing in 2016, when the TRX concept was unveiled at the Texas State Fair. I was there, and was among the many who gave the assembled Ram higher-ups an enthusiastic thumbs-up. That’s what they were hoping to see before they greenlit the project. The pace of development being what it is, and with the redesigned, current-generation Ram 1500 a prerequisite that understandably had to come first, itÂ’s no surprise that weÂ’re only seeing it now as a 2021 model. You may be biting your tongue that I overlooked the Tundra TRD Pro or the Chevrolet Silverado Trail Boss, but neither of those comes close to following the formula established by the Raptor: big engine, a much wider stance than the base truck, greatly enhanced suspension travel, huge tires and swollen fenders to cover it all. Only the Raptor and the TRX fit that mold. For now.   Before I got started, I first pointed the TRX up my RTI ramp and measured its Flex Index score. Please excuse the shaded nose; the truck ran farther up than IÂ’d guessed and literally drove out of the picture. But something in my subconscious warned me to keep the garage door open, which was fortuitous because the nose of the Ram ended up inside. The TRX hiked its front wheel 29 and 7/8 inches off the ground before the left rear tire reached the point of lift-off, and that equates to a climb of 87.4 inches up the deck of my ramp. Divide that by the TRXÂ’s wheelbase of 145.1 inches, multiply by 1,000, and you arrive at a Flex Index score of 602 points. It could have been a few points higher, I think, if I could have straightened out the steering a bit better. But the high-grip cheese grater surface of my ramp was firmly dug in and having none of it. This is an extremely good score for a full-size crew cab pickup. LetÂ’s take a closer look at what made that possible.   The track width of the TRXÂ’s double wishbone front-suspension is a full 6 inches broader than a regular Ram 1500, and you are looking at the parts that are responsible. The lower wishbone (yellow arrow), the upper control arm (green) and the steering knuckle (red) conspire to add 3 inches per side to the TRXÂ’s stance.

Ram 1500 mule caught sporting Mega Cab configuration

Our intrepid spy photographers have once again captured an unusual test mule out in the wild. This time we have a Ram 1500 that looks a little lengthy in the middle. We're pretty certain this is a 1500 and not a heavy duty model judging from the grille and hood. That said, FCA clearly went to great lengths to hide the cab. It's still clear that the rear section is longer than your typical quad cab, leading us to believe that the Mega Cab option will return to the 1500 line. Other interesting details are the covered tailgate and the Chrysler steering wheel in the interior. We're not entirely sure why it's covered up, as it doesn't appear to have a different function, but there could be some styling tweaks for a new trim level. The one part we can see is the tailgate handle, which may reveal some updated camera abilities as the normal location shows a differently shaped camera lens. There are also two small spots that could be cameras, but it's tough to say for sure. Will we see 360-degree imaging on the next Ram? The steering wheel is an unusual inclusion as well. Our photographer suggests that it could be necessary for using the latest UConnect infotainment system. Other than the wheel though, the interior looks identical to the current model. This updated cab option also leaves us wondering about the future of the Ram line. We have documentation that shows FCA plans to launch some type of refreshed Ram for the 2018 model year. So it's possible we're looking at an early test mule for that updated model, and the new cab option could be launched at the same time. In many ways, this Ram brings up more questions than answers.

NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.
