Shock absorber mounts: features, purpose and choosing polyurethane mounts
Knocking over potholes? Has the car started to wander in corners? Most likely the problem is in the upper shock absorber mounts. The shock absorber mount (or shock absorber top mount) is a key chassis element that acts as a damper between the car body and the strut. Today we will tell you everything about these indispensable parts, why a polyurethane shock absorber mount is better than a rubber one, and how to choose quality front shock absorber mounts and rear shock absorber mounts for your car.
What is a shock absorber mount and how does it work?
The shock absorber mount is fixed above the spring in a special "cup" on the body. The strut rod passes through it and moves without extra strain thanks to a built-in bearing. Shock absorber mounts effectively damp vibration, shocks and noise that occur when driving over bumps, making the car's handling smooth and comfortable.
Depending on the suspension design, there are front shock absorber mounts and rear shock absorber mounts. Each has its own features but performs the same function: it protects the body from vibration and ensures a smooth ride.
Main functions of the strut mount:
- Driving comfort: shock absorber mounts absorb vibration and shocks, making the trip pleasant even on a bad road
- Improved handling: the mounts stabilize the car's movement, reducing body roll and ensuring predictable behavior on the road
- Longer shock absorber life: a quality strut mount protects the strut itself from excessive loads and impacts
It is important to understand that the condition of the front mount and the rear mount directly affects not only comfort but also driving safety.
How can I recognize a faulty shock absorber mount?
Worn front shock absorber mounts or a worn rear shock absorber mount have characteristic signs:
- Knocking or squeaking when driving over bumps
- Worse handling, especially in corners
- Vibration in the steering wheel while driving
- Excessive body sway after driving over a pothole
On visual inspection you may notice cracks, deformation, or rubber/polyurethane squeezing out beyond the metal part of the shock absorber mount with its bearing. If any of these symptoms is found, we recommend that you check the condition of the stabilizer bar and the shock absorber mount at a service shop as soon as possible.
Advantages of polyurethane shock absorber mounts
Why buy a polyurethane shock absorber mount instead of a rubber one? Here are the main advantages:
- Exceptional durability: polyurethane strut mounts last up to 3–5 times longer than rubber equivalents
- Resistance to aggressive environments: polyurethane does not break down from grease, fuel or road reagents
- Temperature stability: polyurethane front shock absorber mounts work equally well at -40°C and at +120°C (-40°F to 248°F)
- Resilience and elasticity: the material quickly returns to its original shape after loading, ensuring stable operation
- Quality guarantee: polyurethane front and rear suspension shock absorber mounts at the Kapot.in.ua store come with a 1-year warranty with no mileage limit
How do I choose the right shock absorber mount?
To buy a front shock absorber mount or a rear shock absorber mount correctly, follow these recommendations:
- Exact selection by car model: use your car's VIN or the catalog number of the original part
- Take your suspension's features into account: the geometry of a front shock absorber mount with a bearing can differ depending on the year of manufacture and trim
- Choose quality polyurethane: the material must be wear-resistant and elastic
On the Kapot.in.ua site you can easily select a front shock absorber mount or a rear shock absorber mount by VIN with a guarantee of fit. It is also worth looking at stabilizer bar bushings, which often wear out at the same time as the mounts.
Restoring shock absorber mounts: when is it possible?
If you have a rubber shock absorber mount, it can be restored by replacing the rubber with polyurethane. The process goes like this:
- Cleaning the metal part of the old rubber
- Checking the metal bracket for damage
- Pouring polyurethane in place of the rubber
This method will help you save on repairs. The catalog of Kapot.in.ua includes both new and restored shock absorber mounts. However, remember that with serious deformation of the metal part restoration is impossible and a full replacement is needed.
Where can I buy quality polyurethane shock absorber mounts?
You can buy polyurethane shock absorber mounts at the best prices in the online store Kapot.in.ua. We offer:
- A wide choice of rear strut mounts and front shock absorber mounts
- A 1-year warranty with no mileage limit on all parts
