Word on the street is that the all-new independent rear suspension that premiered on the 2021 Chevrolet Tahoe and Suburban is up to the task of working in GM pickup trucks, as well. According to a recent report from CNET’s Roadshow, the new IRS could “absolutely” handle the workplace abuses required of the Chevrolet Silverado and GMC Sierra, according to chief engineer Tim Asokolis, but would require separate validation testing.

Considering the utilitarian benefits of a live rear axle that keep them relevant in the pickup truck space, we could see this setup find its way into GM’s upcoming electric pickup trucks on the specialized BT1 platform. These trucks, while they will likely demonstrate groundbreaking capabilities for electric vehicles in terms of capabilities, are unlikely to replace ICE trucks anytime soon, just by their nature.

A solid axle is normally more strong than an IRS and can therefore handle more loads when performing tasks like hauling and towing. Its simple design also tends to make it lighter and easier to produce than an independent rear suspension. However, the benefits that come from the integration of an IRS could outweigh the costs of added weight and reduced payload and towing capabilities if the objective was to improve ride quality and handling dynamics.

There are added benefits in the off-road truck and SUV space also. While more complex and expensive, a well done independent suspension could make for a pickup truck or SUV that can traverse multiple surface types more effectively, as the articulation of the suspension is independently handled wheel-to-wheel. We know that Chevrolet is currently working on a rival to the Ford F-150 Raptor currently believed to be called the Silverado ZRX. And while we saw an early teaser with the Hall Racing Silverado with Multimatic DSSV dampers at the 2019 SEMA Show, General Motors likely didn’t show its full hand.

We hope to bring you more detailed information on the viability and the validity of a possible independent rear suspension system coming to the Chevrolet Silverado and GMC Sierra in the coming days.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
