Heavy-Duty Performance
50mm Bore
Shock Absorbers
The industry's largest-bore shock absorbers, engineered exclusively for armoured vehicles carrying B4–B7 ballistic protection. Where standard 30–35mm shocks fade under sustained military use, our 50mm Foam Cell units maintain consistent damping performance regardless of load or operational tempo.
Developed from prime mover technology and refined over 40 years of Australian field use — these shocks are the reason Tough Dog Armoured is trusted by defence agencies across 45+ countries.

Advanced Technology Features
50mm Large Bore
The industry's largest bore diameter allows for increased fluid capacity and superior heat dissipation, preventing damping fade under sustained military and security use.
Multi-Lip Oil Seal
Precision-engineered sealing system prevents fluid loss and contamination across the full operating temperature range — critical for sustained operations in remote environments.
High-Temp Hydraulic Fluid
Formulated to remain stable under extreme heat generated by heavy, continuous cycling. Maintains consistent viscosity where standard fluids would fail, preserving damping force.
20mm Chrome Rod & 70mm Casing
Extra-diameter chrome piston rod and heavy-gauge outer casing deliver superior corrosion resistance and structural integrity under armour loads of 1,500–3,000+ kg.

Tough Dog vs. Standard Shocks
The Case for Upgrading
Why Standard Shocks Fail on Armoured Vehicles
Standard 4WD shock absorbers are engineered for factory vehicle weights of 2,500–3,500 kg. Armoured vehicles carrying B6–B7 ballistic protection packages add 1,500–3,000 kg — often doubling or tripling the suspension load. Under this weight, standard shocks overheat within minutes of sustained use, causing hydraulic fade that eliminates damping control entirely.
Tough Dog Armoured 50mm bore shocks carry more than four times the fluid volume of a standard unit. Combined with Foam Cell technology and high-temperature hydraulic fluid, they maintain consistent damping force across the full operating temperature range — even under sustained convoy use in extreme environments.
