Westralia Springs keeps in stock a large range of new 4WD springs for standard and heavy duty applications for models by Ford, Holden, Jeep, Landrover, Mazda, Mitsubishi, Nissan, Suzuki, Toyota Hilux and Landcruiser.  With so many companies selling aftermarket 4WD springs trying to source quality suspension products can be difficult.  For over 80 years vehicle owners have put their faith & trust in Westralia Springs as they consistently deliver suspension service & advice of the highest quality.  Westralia Spring Works is the sole W.A. authorised distributor for A.P.M. Springs; the largest auto component manufacturing group in Malaysia. While our APM springs are made overseas to ISO 9002 quality they are all designed locally by our experienced spring makers.

Westralia Spring Works designs our springs to give your 4WD increased ground clearance, improved stability and load carrying capacity. While APM products cater for stock lines and fast moving items, it is still more economical to make springs on site for one-off or low volume applications.  With qualified spring makers on site Westralia Springs can hot reset client's existing leaf springs, supply new or custom manufacture.
