An essential part of any vehicle's suspension, flexible mounts and bushings are fitted at the points where the chassis/body of the vehicle connects to the moving components. Their role is therefore to act as a flexible link between the exposed parts, but also to absorb noise and vibration from the road. The most common material used in the manufacture of these components in most cars is conventional rubber. This is cheap , provides decent elastic properties, but its lifetime is severely limited. Over time, due to pressure and other external influences, it loses its elasticity, deforms and in extreme cases even cracks. This of course has a negative effect on the driving characteristics, causing changes in axle geometry not only when cornering, but especially when accelerating and braking. Also, worn out bushings have a big impact on tyre life.
The solution is the use of polyurethane bushings, as they eliminate all the negative properties that classic rubber has.
Advantages:
- High durability compared to rubber bearings
- High flexibility and load-bearing capability, which translates into noticeably more precise driving characteristics, better response and vehicle contact with the road
- High resistance to weather conditions, high operating temperature range, resistance to spreading materials and various chemicals (oils, lubricants...)
- Last but not least, the positive impact on tyre life
Disadvantages:
- Less suspension comfort when using harder 90+ ShA compounds
- Necessity of occasional lubrication
Offer:
In our offer you can find polyurethane silentblocks from two manufacturers. The most popular is POWERFLEX , which has been developing and manufacturing these bushings for over 25 years. It is a top manufacturer that offers comprehensive solutions and a wide range of products not only for general traffic vehicles, but also for racing specials.
Cheaper variant is STORONGFLEX, which offers an excellent price/quality ratio, you can often find polyurethane bushings cheaper than conventional rubber ones at this manufacturer.
Správny výber silentblokov :
Before buying polyurethane silentblocks it is very important to clarify what purpose we want to use the car for. If it is a car that you want to use for normal driving, it is preferable to use silentblocks with less hardness, so that the comfort of driving is maintained. In case of POWERFLEX, its purple bushings (80ShA) and in case of Strongflexe, those bushings are red color (80ShA).
However, if you expect uncompromising handling characteristics from the vehicle or if it is a competition vehicle, we recommend using POWERFLEX black (95AhA) or STRONGFLEX yellow (90ShA) power blocks. With these powerblocks, it must be taken into account that they are already stiff enough and can transmit vibrations and noise into the cabin of the vehicle.
For explicitly extreme purposes, we also offer hard bushing replacements. These specially designed fits are designed for maximum durability and precision in vehicle handling, but they lack any elastic properties and are therefore not suitable for normal traffic.
