To achieve all of this , Alpha has designed its independent coil systems so that there is almost a 90-degree angle between the control arm and the dual Pedders shock absorbers at ride height . This , according to Alpha , is the ideal angle for a comfortable , predictable ride .
Alpha has also developed its own bump stops . Essentially , bump stops are designed to regulate the travel of the trailing arm assemble and serve as a cushion should the suspension bottom out , preventing metal from hitting metal . Alpha ’ s unique top bump stops not only help to protect the spring but prevents the shock absorbers from damage ( popping out , etc .).
The Alpha suspension systems include the ability to adjust toe alignment and camber .
The Alpha Ultra suspension system is a popular choice for hybrid campers .
Independent coil suspension systems generally offer increased ride height and centre ground clearance , and because coil springs are not rigidly fixed to the chassis , there is greater scope to adjust and customise the suspension geometry . Alpha ’ s design – seen on both the Ultra and Extreme systems – includes the ability to adjust toe alignment ( the extent to which tyres ‘ lean ’ inwards or outwards when viewed from above ) as well as the camber ( the inward or outward angle of the tyre when viewed from above ). The adjustment mechanism features a double-locking feature ; however , it ’ s worth noting that adjusting toe and camber should be left to the experts .
The suspension does not just hold up the van ; it has to control the body of the van in dynamic conditions . One final feature found on Alpha suspension systems is the minimal overhang of the trailing arm at the stub axle – again , it ’ s about delivering a stable , predictable ride .
