Description

Designed in Australia, Tough Dog leaf springs offer a spring pack for just about any application you might require. 

Our springs are a proven performer in any situation.

Tough Dog leaf springs are a truly progressive rate leaf spring. 

Each leaf is set slightly higher than the leaf above so there is contact along the whole length of each leaf. 

There are single stage and two stage springs available for different applications. 

Primary and secondary stage leaves ensure that the vehicle’s ride remains uncompromised. 

As the spring is compressed under load, the heavier second stage leaves come into play to prevent excessive sag & remove high stresses from the primary stage.
