The new StockMaster is Ifor Williams’ largest trailer to date with a maximum gross weight of 21 tonnes. The commercial axles and running gear make this trailer the most durable and robust trailer from our range.

The StockMaster is 24’ by 8’ and can be used as either a flat or a livestock trailer.

The trailer has an all over galvanised chassis and a one piece aluminium floor. The very low angle of the ramp (20 degrees) and low bed height is an admirable feature.
