The Tough Dog 45mm “Big Bore” is the largest externally adjustable shock on the market. Nothing else really comes close to this 45mm internal bore in 70mm of external casing. Equipped with a massive amount of all weather oil to withstand the highest temperatures, this is one serious shock.
The 9 stages of adjustment mean you can control the firmness of your shocks easily, and adapt to the conditions as required. Choose a firmer ride for your highway travels, and then dial them down when it’s time to get down to business. 45mm big bore adjustables are designed for big lift applications up to six inches over factory in some vehicles.
Tough Dog adjustable shocks are built tough for the Aussie outback. As well as the Foam Cell insert to combat shock fade, the 45mm adjustable also incorporate an ABS plastic dust shield as well as an external dust wiper seal to protect the shock’s internals from grit which can damage the oil seals around the chrome rod. When fully extended, the shock is at its most vulnerable to damage from side load. The internal bump stop and piston rod guide ensure the shock is supported at the extremes of its travel. Tough Dog big bore shocks also have a DU bushing fitted internally to protect the seals from damage caused by side load at full extension.
