Rear axles 

DAF Components supplies cabs to partners manufacturing all-wheel drive trucks or other special vehicles for construction, forestry, mining industry and other harsh environments.

High efficient rear axles to achieve best in class fuel efficiency

Rear axle designs have been further developed and fast reductions of down to 2.05:1 can be specified for driving with low rpm at cruising speed. The new generation of rear axle differentials features a completely new design of crown wheel and pinion, aimed at highest durability and efficiency as well as extremely low noise levels.

Application of low viscosity oils and low friction wheel end bearings also enhance fuel efficiency.
Lower oil levels in the rear axle further reduce the already best in class axle weight to only 645kg.
