[Update: 26.09.2023] This post was updatedto take more recent information into account. Do you like thick tires in combination with a suspension? Do you like traveling faster? Then it may be worthwhile to install a spring travel limiter, because retrofitting has some advantages. You will find out in the following article what a suspension limiter exactly is, what it actually does and what designs are available for purchase.
What is a spring travel limiter?
The spring travel limiter consists of a hard rubber material or sturdy spring steel and is mounted on the piston rod, on the shock absorber (pierced). At the rear but also often at other points that may vary depending on the vehicle. With the help of the limiter, the vibration or spring behavior of the chassis is influenced and reduced. The soft chassis, which reacts strongly to bumps, can be converted to a harder chassis with a spring-action limiter. The lateral inclination in fast cornering is reduced and even when braking hard or when accelerating a spring limit limiter can reduce the body movements significantly.
Why is a spring limit limiter installed?
Spring travel limiters are particularly popular in the tuning scene, primarily among tuners who have lowered the car. Retrofitting the limiter is intended to additionally protect the body from strong spring vibrations. Even if you have thick tires installed on your vehicle, the suspension travel limiter can help you better control your vehicle on uneven ground and reduce or completely prevent dipping into the wheel arches. You can attach the suspension travel limiter to all four axles and increase driving comfort with the right setting. If your new wheel and tire combination runs the risk of dragging on the wheel arch when it dips into the wheel arches, the suspension travel limiter can help. From a legal point of view, however, this is no longer an alternative if the bike simply does not fit the car or the wheel arch!
Advantages of the travel limit limiter?
If you have decided to install a travel limit, you can benefit from the following benefits:
- Shorten the suspension travel and thus protect the lowered bodywork
- Protect your shock absorbers from bottoming out by retrofitting a spring travel limiter
- Prevent the wide wheels from grinding on the wheel arch
- Keep your vehicle better under control, at higher speeds, even on rough roads
- Improve your driving behavior, with the help of a travel limit
Disadvantages of the travel limiters?
Unfortunately, you can also incur some disadvantages if you use the travel limiters improperly. You should pay attention to this to avoid disadvantages:
- Do not use the suspension travel limiters to protect your lowered car from bottoming out, as this will make the suspension extremely hard.
- Bumps and shocks are transferred more to the body, the suspension, etc.
- If you choose the suspension too hard, you can cause health disadvantages. The impact caused by the rough road is cushioned by your spine
- If the spring adjustment is done incorrectly, you will no longer have control of your vehicle. If the road surface is uneven, at high speeds and the suspension is too hard, you will lose contact with the ground more often
- Never use the travel limiters to retrofit a cheap spacer to avoid the mentioned disadvantages
Which manufacturers produce travel limiters?
If you attach great importance to high quality, then you can choose from a variety of popular manufacturers. You can get model-compatible and universal travel limiters. Manufacturers of travel limiters are for example: Brehma Universal, KW Suspension, Raid hp or SplitFire.
And the legal situation to the spring limit limiter?
Suspension travel limiters are also installed in many cars at the factory. They also serve security purposes there. Suspension travel limiters for retrofitting are nothing different and therefore registration by the TÜV or Dekra does not have to be made. Nevertheless, some manufacturers have an ABE for the limiters. If you go to the TÜV or a police checkpoint, the piece of paper can't do any harm. The TÜV can also declare the installation of spring travel limiters to be inadmissible. This is the case when the shock absorber no longer has any travel and the car rests on the limiters.
The spring travel limiters at a glance:
Suspension travel limiters are special devices used in vehicles to prevent the car from bottoming out on the ground or the tires from dragging in the wheel arch. They are particularly important for lowered vehicles or those with large wheels.
What does a travel limiter do?
- An Suspension limiter is essentially a hard rubber washer or plastic element that clips onto the shock absorber's piston rod. Its presence limits the vehicle's suspension travel so that the shock absorber touches down earlier. This prevents the vehicle from cushioning over the full distance, which in turn prevents components from rubbing on the wheel or the body from bottoming out in lowered vehicles.
Installation and assembly:
- Installing spring travel limiters is relatively easy. They have a slot, similar to rosettes on heating pipes, and can simply be placed around the shock absorber rod. Some high-quality models have pins with which they can be connected to other identical elements.
Materials:
- Travel limiters are available in different shapes, sizes and hole dimensions. Most are made of durable rubber or plastic.
Disadvantages:
- Although they are useful, travel limiters can affect handling. They can lead to harder damping behavior and place greater strain on both the body and the occupants. In the long term they can cause damage to the wheel suspension. At high speeds or with a heavy load, the vehicle may become more difficult to control due to the changed driving dynamics.
Conclusion:
Suspension travel limiters are useful tools, especially for lowered vehicles or those with large wheels. However, they should be used with caution as they can affect driving behavior and potentially cause damage.
