Suspensions Designed, Built and Tested Solely for Australian Conditions

Krueger has developed the only Australian-made suspension, specifically designed for Australian road conditions.

To increase customers’ bottom line, Krueger offers smarter, simpler technology that is lighter, cheaper and easier to install without any compromise to safety and quality. It has successfully been operating in Australia on more than 1,000 semi trailers for over 10 years now, and has been certified as ‘Road Friendly Suspension’ since 2000. It is the only air suspension for a trailer, which is made for Australian conditions!

First Australian Made RFS Suspension

Being wholly Australian-owned, RFS work closely with their customers to develop new designs, both tested and developed under local conditions, in a much shorter time frame than imported brands can offer. RFS Road Friendly Suspension System carries the stamp of Government approval, under the Federal Government ADR requirements.

RFS Highly Competitive Suspension Systems

The RFS Suspension is suited to any brand of cambered axle and has many low tare features that are better or match any competitor products. Krueger has proven that camber axles increase tyre life. The RFS Air Suspension design accepts a cambered axle, which is held in a U-bolt. As a result the axle is easily removed (unlike other brands which are unsuited to cambered axles) saving you costly re-fitment maintenance charges. It all adds up to more payload and improved tyre life, to increase your margins. The RFS Air Suspension also comes as standard, with many new features such as ‘easy align’, which means a wheel alignment can now be adjusted in minutes.
