Heavy-duty shocks:

Their function is mentioned in their name:” heavy-duty”. They are crafted for vehicles with a large centre of gravity. To provide great control over such vehicles it has been designed with a big shaft.

Air shocks:

As the name indicates, these are shocks operated by an air compressor. Although these air shocks are adjustable and assist in uniform weight dispersal, you have to adjust them physically which is quite bothersome.

Overload shocks:

These are another pair of shocks designed for bulky off-road locomotives. Their distinctive feature is a spring coil providing this shock and your car with flexibility and springiness.

Automatic self-control shocks:

These are another category of air shocks that operate by air pumps and provide uniform dispersal of weight. However, the air pumps operate automatically unlike the air shocks mentioned-above.

Quality

After deciding on the type of shock absorber you want, next comes their quality. No doubt every shock absorber comes with an expiry date but how long does it last is the question! Plenty of shock absorbers show off with stainless steel exterior with zinc or chrome coating over it. This layer levels up the toughness of the shock absorber against Corrosion.

Warranty

Last but not the least, warranty. This varies according to the shock absorbers brand. However, it’s best to invest in a shock absorber that comes with a lifetime warranty, and truth be told: plenty of them come with this warranty.
