Everything you NEED to Know About Shock Absorbers

Guide to Buying Shock Absorbers

Shock absorbers are hydraulic (oil) pump-like devices that help to control the impact and rebound movement of your vehicle’s springs and suspension. Along with smoothing out bumps and vibrations, the key role of the shock absorber is to ensure that the vehicle’s tyres remain in contact with the road surface at all times, which ensures the safest control and braking response from your car. 

Essentially, shock absorbers do two things. Apart from controlling the movement of springs and suspension, shock absorbers also keep your tyres in contact with the ground at all times. At rest or in motion, the bottom surface of your tyres is the only part of your vehicle in contact with the road. Any time that a tyre’s contact with the ground is broken or reduced, your ability to drive, steer and brake is severely compromised. Despite popular belief, shock absorbers do not support the weight of a vehicle, that is the job of the springs.

Finding the right type or brand of shock absorber can be a difficult task as the perfect fit can vary greatly depending on your vehicle’s need and personal preferences. Not to worry, we’ve formulated the ultimate guide for choosing shock absorbers.

All shock absorbers have different types of styles to cope with different styles of driving and types of vehicles. Shock absorbers can either come equipped with twin tube or monotube construction each with their own benefits. Here’s what types of shocks to consider when choosing the right suspension system for your vehicle:

OE Replacement:

  • Designed to simply restore your vehicle's suspension back to the level of balance and comfort it had from factory.

  • Cheaper and less dramas with installation.

Heavy Duty/Off-Road:

  • Designed with larger oil tubes and high capacities for heat and pressure for increased performance offroad.

  • Made of thicker heavier duty materials to deal with increased level of shock.

  

Foam Cell Heavy Duty: 

  • Microcellular foam insert that helps to drastically reduce the effects of shock fade, allowing your shocks to perform better for longer, even on the harshest of corrugations.

  • This eliminates the possibility of bubbles forming, allowing the shock to get on with the job with an unparalleled resistance to shock fade.

 Monotube: 

  • Monotube shock absorbers are designed for next level performance over twin tube shocks in those hot, harsh, demanding conditions.

  • By utilising the monotube design, monotube shock absorbers are able to resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.

 Monotube Remote Reservoir:

  • Combining the best in high performance race-bred Monotube technology, with an all new 3-way damping adjustment system to turn your 4x4 into the ultimate off-road machine.
