Many sedan owners Nissan Teana are faced with the problem of insufficient ground clearance, especially on Russian roads. Factory ground clearance is often insufficient to overcome deep holes, high curbs or snow-covered yards. One of the most popular solutions to this problem is to install spacers under the shock absorber struts, which allows you to physically raise the car body above the road.
However, interfering with the suspension geometry is not just replacing the bolts with longer ones, but a complex engineering task. Incorrect selection of spacer height or type can lead to accelerated wear of parts, wheel alignment problems, and even loss of controllability. In this article we will analyze in detail what types of spacers exist and how they affect the characteristics Nissan Teana and what risks the installation poses.
Why Teana owners need a suspension lift
Sedan Nissan Teana was initially positioned as a comfortable car with a soft suspension, aimed at urban conditions. Factory settings provide a smooth ride, but make the car vulnerable to serious obstacles. Increasing ground clearance becomes a necessity for those who often drive a car outside the city or live in areas with poor quality asphalt.
The main purpose of installing spacers is not only to protect the bottom, but also to improve cross-country ability. The raised body allows the wheels to more easily overcome uneven surfaces without touching body or suspension components. This is especially true for versions Nissan Teana with large disks and low-profile tires, where the shock absorber range is minimal.
It is important to understand that a suspension lift changes the character of the car. The car becomes a little stiffer on small bumps, but feels more confident on large off-road terrain. However, increasing the height too much can cause the center of gravity to move too high, affecting cornering stability.
⚠️ Attention: Installing spacers larger than 30 mm without replacing springs and shock absorbers with reinforced versions is strictly not recommended, as this will lead to rapid failure of the standard struts.
Types of spacers: polyurethane or aluminum?
On the auto parts market you can find two main types of spacers for the front and rear suspension. The first option is products made from technical polyurethane. They have high elasticity, which allows them to dampen vibrations and not add unnecessary rigidity to the suspension. Polyurethane spacers often have a more complex shape that follows the geometry of the shock absorber cup.
The second type is rigid aluminum spacers. They are made of aircraft alloy and are characterized by high strength and durability. Aluminum is not afraid of moisture and corrosion, which is important for a suspension that is constantly in contact with reagents and water. However, due to their rigidity, they can transfer more shock to the body when driving over obstacles.
The choice of material depends on your priorities. If maximum smoothness and maintaining factory comfort characteristics are important to you, it is better to choose high-quality polyurethane. If you are planning a serious increase in ground clearance and driving on dirt roads, an aluminum spacer will be a more reliable solution, since it does not deform under load.
- 🔹 Polyurethane spacers are ideal for urban use and small elevators (up to 20 mm).
- 🔹 Aluminum spacers are preferred for increasing ground clearance by more than 25 mm and operating in difficult conditions.
- 🔹 When choosing, be sure to check the presence of anti-corrosion coating on metal products.

The influence of the elevator on wheel alignment and geometry
Any intervention in the height of the rack will inevitably change the wheel alignment angles. When lifting the body to Nissan Teana The angle of inclination of the shock absorber changes, which leads to a shift in the camber and toe of the wheels. This phenomenon is called caster and camber variation. Standard wheel alignment adjustments often do not completely compensate for these changes.
If the correct adjustment is not made after installing the spacers, the vehicle may begin to “pull” to one side and the tires will wear unevenly. The inner or outer part of the tread can wear out in just one or two thousand kilometers. This is a direct financial loss and reduced traffic safety.
To solve this problem, additional adjusting bolts (eccentrics) are often required, which allow you to expand the range of camber adjustment. Without them, it will be impossible to return the wheel to the correct position with a significant lift. A professional service should use the stand taking into account the new suspension parameters.
⚠️ Attention: After installing spacers of any height, it is imperative to perform a wheel alignment, otherwise you will ruin the new set of tires within a month.
Step-by-step instructions for installing spacers
The process of installing spacers under the racks Nissan Teana requires a lift or inspection hole, as well as a set of high-quality tools. The work begins with dismantling the wheel and disconnecting the shock absorber strut from the steering knuckle. Be extremely careful with brake hoses and tie rod ends to avoid damaging them.
After removing the strut, it is necessary to disassemble the shock absorber using a special spring tightening tool. This is a critical step because the spring is under enormous tension. Install the spacer onto the upper spring cup, making sure it fits snugly and is not distorted. Reassemble the strut, monitoring the tightening torque of the shock absorber rod nut.
Install on the vehicle in reverse order. Pay special attention to tightening the lower strut mount and the steering knuckle bolts. Use a torque wrench to prevent stripping threads and ensure correct tightening torque. Do not tighten the suspension bolts until the vehicle is lowered onto its wheels, as the rubber bushings may become twisted.
☑️ Preparation for installing spacers
- 🔹 Always replace old mounting bolts with new ones if they show signs of corrosion or stretching.
- 🔹 Use special spacers with guide pins for precise fixation on the spring cup.
- 🔹 After installation, be sure to check the operation of the brake system and the absence of snags on body elements.
What to do if the spacer does not fit into place?
It often happens that the standard spring cup is deformed or has metal deposits on it. In this case, you need to carefully clean the surface with a file or sander, but do not overdo it, so as not to weaken the cup structure. Also check that you have not mixed up the left and right spacers, as they may have different seat shapes.
Risks and negative consequences for the suspension
Don't think that spacers are a panacea. They also have significant disadvantages that you need to be aware of before purchasing. The most important thing is to change the operation of the suspension arms. When the body is lifted, the levers change their operating angle, which increases the load on the silent blocks and ball joints. The service life of these parts can be reduced by one and a half to two times.
It is also worth considering the change in the angle of operation of the shock absorber. Standard shock absorbers are designed for a certain stroke, and when spacers are installed, they can operate in an “inconvenient” range, quickly losing their damping properties. This can lead to the suspension becoming too stiff or, conversely, starting to hit the pits.
Another factor is the change in steering geometry. The steering angle of the wheels changes, which can lead to increased steering effort and vibration when driving at high speeds. In some cases, it may be necessary to install sway bar extensions to restore proper angles.
Before installing spacers, check the condition of all rubber suspension elements (silent blocks, boots). If they are worn out, replacing them immediately after a suspension lift will save you money in the future as the new parts will last longer at the correct angles.
Comparison of suspension characteristics before and after installation
To clearly understand how the car’s behavior will change, let’s consider the main parameters. It is important to note that results may vary depending on the specific modification Nissan Teana (J32 or J33) and the type of spacers installed. Data are given for average values when installing a 25 mm thick spacer.
| Parameter | Factory condition | With 25 mm spacers |
|---|---|---|
| Ground clearance (clearance) | 160 mm | 185 mm |
| Pitch angle | 18 degrees | 21 degrees |
| Suspension stiffness | Soft | Average |
| Silent blocks resource | Basic | Reduced by 30% |
| Effect on center of gravity | Low | Promoted |
As can be seen from the table, increasing the ground clearance gives a noticeable gain in cross-country ability, but requires readiness for more frequent suspension maintenance. Comfort on the highway may decrease slightly, but in the urban cycle the difference is often unnoticeable to the average driver. The main thing is not to exceed reasonable lifting height limits.
⚠️ Attention: When installing spacers larger than 35 mm, it may be necessary to replace the front shock absorbers with extended ones, otherwise the rod will hit the upper limiter and damage the internal part.
Increasing the ground clearance on a Nissan Teana through spacers is a compromise between cross-country ability and suspension life, which requires a competent approach to the selection of components and mandatory adjustment of wheel alignment angles.
FAQ: Frequently asked questions
Is it possible to install spacers only on the front suspension?
Technically, it is possible to install spacers only at the front, but this will lead to a change in wheel alignment and a change in the nature of control. The car will become prone to understeer and the rear end may become less stable. It is recommended to install spacers as a set (front and rear) to maintain balance.
Do I need to change springs when installing spacers?
When installing spacers up to 20-25 mm, standard springs usually withstand the load, but their service life is reduced. If you are planning a lift of more than 30 mm or often load the car, it is strongly recommended to replace the springs with stiffer or longer ones to avoid sagging and breakdowns of the suspension.
How do spacers affect the operation of ABS and ESP?
Spacers can change the operation of the wheel angle sensors and height sensors, if your vehicle has them. In some cases, the stability control system (ESP) may begin to generate false errors or turn off. After installation, it is necessary to check the operation of the electronic systems and, if necessary, carry out adaptation.
How long does it take to install spacers?
Installing spacers on both axles Nissan Teana It takes a professional technician from 2 to 4 hours. This time includes dismantling the wheels, disassembling the struts, installing spacers, assembly and the mandatory wheel alignment procedure. Do-it-yourself installation may take longer, especially if you don't have a special tool to compress the springs.
Do spacers affect the car's warranty?
If your car is still under warranty, installing spacers may result in denial of warranty repairs for the suspension and related components. The dealer may argue that changing the suspension geometry led to accelerated wear of parts. It is recommended that you consult your authorized dealer before making changes.
