Difference Between Shock Absorbers vs Struts
Author: Toby Date Posted:3 October 2025
Ask around and you’ll hear it — some drivers reckon shocks are all you need, while others swear struts are the secret to a smoother ride. Truth is, it’s not about picking sides. Both do different jobs, and if you don’t know which one your car relies on, you could be throwing money at the wrong repair. Let’s break it down so you know exactly what’s what.
Are Shock Absorbers and Struts the Same Thing?
Not at all.
A shock absorber is a single component that’s fitted alongside other suspension parts. Its main job is to dampen the bouncing motion of your springs, so your tyres stay firmly on the road. Think of shocks as the referee in a footy match — they don’t play the game or hold up the field, but they make sure everything stays under control.
A strut, on the other hand, is a complete assembly that not only contains a shock absorber inside it but also acts as a key structural part of the suspension. Struts often form the backbone of the front suspension, connecting to the steering system and helping set alignment angles. They support the vehicle’s weight, absorb bumps, and even influence how your car corners. In that same footy analogy, struts are like the stadium framework — they hold everything together, while still being part of the action.
Because of these differences, you can’t simply swap a shock absorber where a strut belongs, or vice versa. If your car was designed with struts, it needs struts. The same goes for shocks. Mixing them up can cause serious handling issues and even damage other suspension components.
The Key Differences
- Function – Shocks control movement, struts control movement and support weight.
- Design – Shocks are a standalone component; struts are a complete suspension assembly.
- Cost – Struts tend to be pricier to replace since they’re more complex and critical to overall suspension geometry.
What Shock Absorbers Do
Shock absorbers, or “shocks,” are designed to control the up-and-down motion of your suspension. Without them, every bump, pothole, or dip in the bitumen would leave your car bouncing around like a trampoline. Shocks don’t support the weight of your car—they simply manage the movement of your springs to keep your tyres in proper contact with the road.
What Struts Do
Struts, on the other hand, combine multiple suspension components into one unit. They act as a structural part of your suspension system, supporting the weight of the vehicle while also doing the job of a shock absorber. Struts are often found in front suspensions and play a big role in steering, alignment, and handling.

Which Suspension Setup Suits Your Vehicle?
Many passenger cars and SUVs come with struts in the front and shocks in the rear, but it’s not the same across the board. The right setup depends on your vehicle’s design and how you use it.
- Everyday commuters – If you’re mostly driving in the city or on highways, chances are your car relies on struts in the front. They provide stability, comfort, and precise steering — perfect for daily driving.
- 4WDs and utes – Off-road rigs and load carriers often lean on heavy-duty shocks in the rear to handle rough tracks, towing, and heavy payloads. Some may still run front struts for steering control, but robust shocks at the back help manage the extra weight and terrain.
- Performance vehicles – Sportier cars may feature struts in the front to sharpen handling while using tuned shocks in the rear for improved grip and cornering balance.
If you’re unsure what your vehicle runs, a quick look in your owner’s manual or a chat with a trusted mechanic will point you in the right direction. Matching the right part to your driving style not only keeps your ride safe but also ensures you get the most out of comfort, handling, and tyre life.
Time to Replace Your Shocks or Struts?
Both shocks and struts are essential for safe, smooth driving. Worn-out parts can lead to poor handling, uneven tyre wear, and longer stopping distances—none of which you want when driving in Aussie conditions. If it’s time for a replacement, you’ll find a solid range of both available at our auto parts online store.
