RV PROFILE
ULTRA FOR SEMI- OFFROADERS
Alpha ’ s Ultra setup is designed for semi-offroad conditions – national parks , some gravel undulations , etc ., rather than the worst that Cape York could throw at it .
It is available in a few different capacities . For single-axle vans , Alpha has a setup rated to 1600kg , so while you won ’ t necessarily find it on a full caravan , it ’ s a popular choice for camper trailers and smaller hybrid vans .
For caravans , the Ultra system is available in weight ratings up to 3300kg ( tandem-axle with 10in brakes ), and 3500kg ( tandem-axle with 12in brakes ).
Even ' tradie trailers ' are suitable for these suspension systems .
There ' s almost a 90-degree angle between the control arm and the dual shock absorbers on both the Extreme ( shown here ) and Ultra suspension systems .
EXTREME
Extreme is Alpha ’ s offroad suspension system . It is available in a weight rating of 2750kg ( single-axle with 12in brakes ) and up to 4400kg ( tandem-axle with 12in brakes ).
Alpha ’ s premium suspension system , though , is the Air-Bag Extreme setup , which allows the user to raise or lower either side of the van at the push of a button , with the desired ride height maintained regardless of the load .
The airbag system is available in four different options : Type 1 , which includes external inflation points only ; Type 2 , which includes an onboard 12V air compressor and remote actuated valves ; Type 3 , which includes the features of Type 2 plus an air tank and tyre inflation kit ; and Type 4 , which includes the features of Type 3 plus a self-levelling system for full or semi-automatic control .
