Torsion bars are key components that play a role in improving how your vehicle handles in various weather conditions. If you're curious about whether your 2007 Chevrolet Silverado has torsion bars, the answer isn't straightforward. In 2007, General Motors equipped the Chevrolet Silverado with torsion bars on the all-wheel drive models, running from the front A-arms to under the transmission. Meanwhile, two-wheel drive models of the '07 Silverado are equipped with coil-over shocks that provide a similar but limited function. Therefore, torsion bars are present in your Silverado if it is a 4WD model, which is the case for most Silverado configurations. There's a strong possibility that your truck has torsion bars.
The 2007 Chevrolet Silverado is equipped with front torsion bars that are beneficial for driving off-road.
The last two responses may be somewhat off the mark. Although MOST 2007 Silverado trucks come with a torsion bar setup, the ones with the Z71 suspension do not. Instead, they have a coil/strut front suspension setup that is often confused with a coilover. I have personal experience owning both configurations.
My 2007 model does not come equipped with torsion bars.
My 2003 Z71 comes with torsion bars, but my 2007 Avalanche 4WD doesn't have them.
My Tacoma from 2009 also comes with those features.
My 2007 Silverado LS, equipped with 4WD, does not come with torsion bars.
