The Difference Between Shocks and Struts
Off-roading and overlanding are exhilarating experiences; the rough terrain and unpredictable obstacles create a challenge that's hard to resist. While the rest of the world seeks smooth roads, you're in search of untraveled trails; exploring off the beaten path can show you the rawest forms of nature. However, understanding the basics of vehicle mechanics can make the most of off-road trips. This guide will teach you the differences between shocks and struts so you can understand how they can improve your driving experience.
Shocks and struts, such as Ironman 4x4’s Foam Cell Pro units, are critical parts of a vehicle's suspension. These components keep the tires on the ground and provide a smooth ride. The Foam Cell Pro shocks and struts provide exceptional ride quality, stability, and handling both on and off-road. Built around superior strength and durability at a great value, Foam Cell Pro saves you money to put into the fuel tank so you can get out and explore.
But understanding what separates shocks and struts can help you make informed decisions about their maintenance and future replacements. Keep in mind: different vehicles have a different combination of shocks, struts, or both.
What Are Shocks?
Shocks are simpler than struts—they are typically comprised of a single hydraulic cylinder with mounts on the top and bottom. Inside there’s a piston, valve, and oil and gas. The piston moves up and down inside the cylinder in response to the road’s bumps and irregularities. As the piston and valve move against the oil, the shocks absorb the impact and dampen the effect by slowing the pistons, preventing your vehicle from bouncing around when moving. Different applications will have different valving, oil, and gas depending on the shock’s application.
Jeep Wranglers and Gladiators, for example, use shock absorbers at all four corners. Other vehicles, such as a Toyota Tacoma or 4Runner, will use shocks on the rear, but struts for the front.
Struts Explained
Struts are more complicated than shocks as they perform two roles—dampening the bumps from the road and supporting the vehicle’s weight. Unlike shocks that only cover the up-and-down motion of the vehicle, struts provide both up-and-down and side-to-side support and usually mount differently to the vehicle than shocks. Struts consist of a hydraulic cylinder with a piston, valve, and oil/gas, but there’s a coil spring on the outside that supports the vehicle in movement. While they are similar to shocks, they’re different due to their configuration and role in the suspension system.
Most modern 4x4 or AWD vehicles will use front struts if they have independent front suspension. This includes Toyota Tacoma and RAV4, as well as the Subaru Crosstrek, Forester, and Outback. Ironman 4x4 has a variety of its ATS suspension for Subaru models. It is rare to find any vehicle using struts at the front and rear.
Off-Road Upgrades
Shocks and struts play a crucial role in your off-road vehicle. In conjunction with its springs, the shocks and struts help your rig’s tires remain on the road by controlling its vibrations from moving over the ground. Bumpy roads can lead to an erratic ride, but a good suspension system will keep things in check by keeping the vehicle in control.
Choosing the right suspension systems allows you to fine-tune how these components perform while you drive off-road and on. When paired with the right springs, you can add increased off-road capability letting you explore more safely and confidently. It’s important to have a basic understanding of the differences between shocks and struts.
At Ironman 4x4, our off-road suspension kits include Foam Cell Pro Kits that are nearly indestructible to ensure you have smooth and enjoyable off-roading excursions. Never rely on a suspension system that is bound to fail—equip your rig with shocks, struts, and accessories that’ll enhance your driving experience!
