Owners Nissan Almera G15 often encounter the problem of the rear suspension sagging when loading the car. Standard suspension elements are designed for standard operating conditions, but under the conditions of our roads and frequent transportation of goods, they quickly lose their characteristics. Installation reinforced springs becomes one of the most effective solutions for restoring body geometry and increasing cross-country ability.
Many car owners are wondering whether it is worth replacing factory parts with tougher analogues. Nissan Almera in the back of the G15 it has a fairly soft suspension, which is good for an empty city, but critical when transporting passengers or luggage. The right set reinforced springs will allow you to avoid “dive” when braking and rolls when cornering, while maintaining an acceptable level of comfort.
Why does the rear suspension of the Almera G15 sags?
Rear beam design Nissan Almera G15 involves the use of coil springs, which are subject to metal fatigue over time. This is a natural process, but it is aggravated by the quality of the road surface and overloads. The main reason for subsidence is the deformation of the coils under the influence of constant weight, which leads to a decrease in ground clearance and deterioration in controllability.
In addition, the factory setting is often aimed at minimizing vibrations when the vehicle is empty. When four passengers sit in the cabin and luggage is added to the luggage compartment, the standard springs are compressed to their limit. In this position, the shock absorbers lose effectiveness, since their compression stroke becomes insufficient to absorb shocks. This is where they come on stage reinforced springs with increased pitch or wire diameter.
Types of reinforced springs and their characteristics
The auto parts market offers several types of reinforced elements for Nissan Almera G15. The most popular are springs with an increased pitch of coils in the upper part. Such products allow you to maintain a soft ride on small bumps, but work harder when fully loaded, preventing the body from lowering all the way.
Another option is springs with a constant increased wire diameter along the entire length. This gives maximum rigidity and durability, but may have a negative impact on comfort when the vehicle is empty. The choice depends on your priorities: if you often carry loads, it is better to choose the option with constant reinforcement. If the load is episodic, a combined step will be optimal.

- ⚙️ Thick wire springs: maximum stiffness for tough conditions
- 🔧 Combination kits: the optimal choice for mixed driving styles
Leading manufacturers and brands
When choosing spare parts, it is important to pay attention to the reputation of the manufacturer. For Nissan Almera G15 brands specializing in suspension tuning have proven themselves well. Quality reinforced springs undergo heat treatment and have an anti-corrosion coating, which is critical for our climate.
You should avoid cheap analogues without certificates, as they may have incorrect coil geometry. This will lead to uneven wear of the shock absorbers and the appearance of squeaks. It is better to overpay for a proven brand than to change the suspension twice a year.
⚠️ Attention: Never buy springs without manufacturer's markings. A fake may not withstand the load and burst when driving over uneven surfaces, which will lead to loss of control.
Replacement process and important nuances
Replacing rear springs with Nissan Almera G15 requires a lift or inspection pit. The procedure is not overly complicated, but it requires care when working with compressed elements. It is necessary to dismantle the wheel, unscrew the lower shock absorber mounting bolt and carefully remove the old element.
It is important to follow the tightening order of fasteners. The lower shock absorber bolt is tightened only after the suspension has returned to its operating position under the weight of the vehicle. Otherwise, the threads may be damaged and the spring tension will be incorrect. Use a torque wrench to check the tightening torque.

Effect on ground clearance and handling
Installation reinforced springs inevitably changes the characteristics of the car. The most noticeable effect is the increase in ground clearance. For Nissan Almera G15 this means better off-road performance and protection of the thresholds from snow and ice in winter. However, you should not expect a miracle: the difference will usually be 2-3 centimeters.
Handling is also changing for the better. Body roll in corners is reduced, the car becomes more composed and predictable. But there is also a flip side to the coin: on bad asphalt, vibrations will be transmitted to the body more strongly. Passengers may experience harsher impacts when driving over speed bumps.
| Parameter | Factory spring | Reinforced spring |
|---|---|---|
| Ground clearance (empty) | 160 mm | 165-170 mm |
| Hardness | Average | High |
| Load capacity | Up to 400 kg | Up to 600 kg |
| Comfort (empty) | High | Medium |
⚠️ Attention: After installing reinforced springs, be sure to check the wheel alignment angle. Changing the suspension geometry can lead to accelerated tire wear if adjustments are not made to the wheel alignment.
Shock Absorber Compatibility
The question often arises whether shock absorbers need to be changed during installation. reinforced springs. Ideally, yes. Shock absorbers are selected according to the stiffness of the springs. If you put stiff springs on old shock absorbers, they may not be able to cope with damping, which will lead to their rapid failure.
However, if your stock shock absorbers are in excellent condition, you can try leaving them. But you should understand that their service life will be shortened. For Nissan Almera G15 There are special kits where the springs and shock absorbers are matched to each other by the manufacturer. This eliminates the need to select parts separately.
What to do if the spring is stuck?
If the spring is stuck in the seat, do not hit it with a hammer. Use a special lubricant or gently roll it around so as not to damage the body paint.
Before installing new springs, clean the seats from dirt and rust, and then apply a layer of protective compound to avoid corrosion and squeaks.
Cost and payback
The price of reinforced springs varies depending on the brand and production technology. Budget options can cost much less, but their service life often does not exceed 30-40 thousand kilometers. High-quality products from trusted manufacturers are more expensive, but they last for years, maintaining their characteristics.
The payback for installing heavy duty springs for commercial or outdoor use is clear. You save on repairs to shock absorbers and body parts that suffer from overload. For simple urban use, the solution is also justified if you often carry passengers or heavy loads.
Installing reinforced springs is an investment in preserving suspension life and improving vehicle handling under load.
Common mistakes when choosing
One of the most common mistakes is choosing springs that are too high. This leads to the fact that when the car is empty, the car becomes too rigid, and the shock absorbers work at the limit of their travel. Reinforced springs should be tailored to the specific needs of the owner, and not just be the highest in the line.
Another mistake is buying springs without taking into account the body type. Although Nissan Almera G15 has a unified platform; there may be nuances depending on the year of manufacture and the sales market. Always check part numbers before purchasing.
- ❌ Buying springs without checking compatibility with the VIN code
- ❌ Ignoring the condition of shock absorbers before installation
- ❌ Installing springs that are too stiff for the city
Suspension tuning results
Replacing springs with Nissan Almera G15 is an effective way to update your car's performance without breaking the bank. The right choice of parts will allow you to forget about body sagging and get more confident behavior on the road. The main thing is to approach the issue wisely and take into account the operating conditions.
Remember that a suspension is a complex system where all elements are interconnected. Changing one parameter affects the others. Therefore, after installation reinforced springs It is recommended to carry out diagnostics of the entire chassis to ensure that there are no hidden problems.
Is it possible to install springs from another model?
Installation of springs from other models is possible only with specific adapters and a complete recalculation of the characteristics, which is highly not recommended without experience.
⚠️ Attention: Regularly check the condition of the springs for cracks and signs of corrosion, especially after the winter period of using reagents.
