Last summer, we shared how the 2021 Chevy Tahoe will incorporate an independent rear suspension. Now, it seems that GM will also introduce IRS on two additional 2021 models: the Chevy Silverado and GMC Sierra. Per Autoblog, the IRS system on the two models should be some version of the four-link IRS that the new Tahoe and Suburban have.

Details about the IRS on the Silverado and Sierra

According to GM Authority, electrification is the primary reason the brand decided to bestow IRS on the upcoming Silverado and Sierra. GM intends at least one of these models to have an electric variant and an IRS is more compact than a solid rear axle, allowing more space for the electric model’s battery pack.

Though, IRS definitely has some additional perks. For starters, it results in a smoother ride. That’s because the system dampens the shock of one wheel hitting a pothole or bump in the road. With a regular suspension system, the impact transfers through the axle, spreading to the entire vehicle. Cornering is another key benefit. Lastly, an IRS system provides excellent traction and stability on rough terrain for more confidence behind the wheel when off-roading.

More IRS rumors

The Silverado and Sierra aren’t the only ones that will soon offer the option of IRS. Per Autoblog, the brand will introduce this system on the next-gen GMC Yukon and 2021 Cadillac Escalade early this year.

It will be interesting to see GM’s trajectory in the next few years as it gradually shifts to a more electric focus with its truck lineup. If this anticipated trend plays out, it’s possible that solid rear axles will become extinct on certain pickup models.
