The heavier the vehicle is, the more energy it needs to get moving. Heavier vehicles have greater inertia and greater rolling resistance, which both contribute to increased fuel consumption. Reducing weight is a very effective way to improve a vehicle’s efficiency (RMI 2011).
Increased weight (typically seen with rear sagging caused by heavy loads) decreases the available compression travel for normal suspension operation thus increasing the frequency and severity of contact with the bump stops.
How much weight can a car suspension take?
Answer provided by. While load capacity varies between different types of cars, the general consensus is that your average car can hold about 850 lbs. This is the equivalent of five 170-pound passengers.

When you overload a vehicle it puts tons of strain on it. The tires can wear out quickly as well as overheat. This leads to expensive tire failure and the possibility of a dangerous blowout. Extra strain means the engine is also working harder to make the vehicle move.
Do heavier cars ride smoother?
Avoid bigger wheels if you want a smoother ride.
As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car.
How much play should a shock absorber have?
On straight axle suspension systems, there is a 1 to 1 ratio between the movement of your shock and your wheel. That means if your wheel moves one inch, your shock extends or compresses one inch. In these applications 2.5 inches of shock travel in both directions (compression and extension) should generally be enough.
How long do shocks last on a truck?
“With heavy use, you could be looking to replace them at 40,000 or 50,000 miles or sooner. Under normal conditions, 75,000 to 90,000 miles might be reasonable.”
How much does it cost to replace shocks?
Shock Replacement Cost
The average total cost to replace a pair of shocks will run about $250 to $580. An individual shock absorber will cost around $50 to $140 so parts alone will set you back between $100 and $280. A couple hours of labor to do the job is an additional $150 to $300.
A thorough inspection should uncover what parts, if any, actually need replacement. The springs in your vehicle’s suspension do most of the shock damping. The shocks and struts improve the ride and reduce the bouncing caused by springs compressing and releasing so you don’t go boing-boing down the road.
How many miles do shocks last?
Generally, shocks and struts wear out every 50,000-100,000 miles. If you’re a more aggressive driver and/or frequently drive on rough roads, they will wear out faster. Shocks and struts don’t go out all at once; they deteriorate slowly over time.
How long do shocks last?
On average, if your car has been “babied,” you can expect your shocks/struts to last about 10 years. If you have really used your car like a workhorse, 5 years is probably all you can expect. This means that for the average driver, 7 or 8 years is the maximum life expectancy of most shocks and struts.
How long should shock absorbers last?
If you’re city-based and drive carefully all the time on well-maintained, perfectly smooth tar roads, your shocks could last up to 10 years. But for those of us who may hit potholes from time to time and drive on dirt roads now and then, expect to get around 5 years from your shock absorbers.
What happens when you drive with bad shocks?
Loss of handling and control – Driving with failing shocks or struts has a direct impact on your ability to control your vehicle. You may notice that your vehicle bounces excessively, rolls or sways abruptly when making a turn, or that you feel out of control when hit by a cross wind.
Bad strut sounds are usually described as a hollow clunking or banging type of sound. You’ll typically hear the noise when the vehicle is traveling over irregularities in the road. Most front strut assemblies also have a bearing at the top.
What can damage shock absorbers?
What causes wear and tear on your shocks?
Potholes. If you are driving on bad roads or hitting potholes often this will cause your vehicle to rebound more frequently and can damage your shocks.
Dirt roads. When travelling on dirt roads a lot of dust is generated in the air.
Mud.
How do I know if my shocks are blown?
Why does my car jump to the side when I hit a bump?
Since your vehicle moves all over the road after a bump, this indicates that your tires are indeed not staying firmly planted and are bouncing uncontrollably. This continual bouncing of the suspension will prematurely wear out other front-end components and cause the tires to wear unevenly.
How do I know if I need new shocks?
The most obvious sign of a problem with your shocks or struts is that your car is giving you a much more uncomfortable ride than normal. You’ll feel bumps more, so the ride will feel rough.
