Shock Absorbers

Heavy Duty Shock Absorbers
for Truck, Trailer & Severe Duty Applications

For more than 30 years America’s heavy duty truck, bus and severe service fleets have trusted Marathon Brake Systems to provide Best-in-Class friction materials that deliver stopping power and the longest service life. Now Marathon is introducing a complete line of heavy duty shock absorbers for these same fleet applications. Marathon shock absorbers are designed and built to provide a comfortable, smooth ride and reduce vibrations from suspension systems. These hydraulic shocks feature rugged construction with reinforced welds, tough end mounts and durable piston seals to provide consistent performance over the life of the shock.

Top-Performing Hydraulic Shock Design

  • Hydraulic stop design outperforms market leader
  • Seals and valves facilitate piston dampening in both up and down movements
  • Smoothness of vibration absorption improves comfort and durability
  • Consistent performance over life of shock improves tire wear and lessens component wear

High Performance Hydraulic Oil

High viscosity oil provides excellent characteristics through all types of weather and extreme heat generated in severe service applications.

Issues with Worn Shock Absorbers

  • Loss of stability and driver control
  • Tires laterally gliding when cornering
  • Increased tire wear
  • Increased braking distance
  • Wheels not on road as tight, increase hydro-planing risk
  • Fatigue of vibration sensitive components

10 Signs of Worn Shocks

  1. Over 50,000 miles
  2. Nose dives when braking
  3. Excessive bouncing on rough roads
  4. Greater veering in cross winds (especially with heavy loads)
  5. Excessive lean or sway in turns
  6. Steering wheel vibration
  7. Uneven or premature tire wear
  8. Fluid leakage from shock
  9. Dented or damaged shock housing
