Without suspension in a vehicle the occupants would feel every bump in the road making for a very uncomfortable ride in addition to which the road handling and braking of the vehicle would be badly affected. Vehicle suspension consists of a system of springs, shock absorbers and linkages connecting the vehicle to the wheels.

At Selecta Tyre Ltd we supply and fit high quality parts for all your suspension needs.

Suspension Overview

Shock absorber regulates the movement of the spring

Objective: To keep the tyre in contact with the road by pushing it down

• 
  With springs but no shocks, bouncing around a lot
• 
  With springs and worn shocks, bouncing around less
• 
  With springs and fully working shocks, tyres maintain contact with the road

• 85% of all vehicles which go to the scrap yard still have their original shocks
• Shocks & springs are only replaced when they have failed
• Shock absorbers are a safety critical component and should be treated as a maintenance item

  • Cornering issues
  • ESP and ABS functioning reduced
  • Increase stress and wear on other components
  • Increased tiredness when driving

How Do Shocks Wear?

Wear is gradual

• Oil passes through the valves with every movement of the car
• 1,000 times per mile for 1st valve
• After 75,000 miles, that’s 75,000,000 times!
• Valves loosen up, allowing oil to pass through piston faster
• Symptoms are harshness, bouncing
