The FLD SD is the granddaddy of Freightliner's family of severe-duty vehicles. It features a heavy-duty chassis with frame rails rated to 120,000 psi and a durable yet lightweight reinforced aluminum cab to maximize payload. With engine options up to 550 hp, the FLD SD has the raw strength and agility required to muscle through severe environments and extreme construction conditions to deliver maximum productivity. The Business Class M2 112 trucks are durable and efficient co-workers to the FLD SD, providing a comfortable cab, high visibility and up to a 55 degree wheel cut for excellent job site maneuverability. With engine combinations up to 450 hp the Business Class M2 112 is ready to get the hard work done. And when you combine that with commercial truck financing from Freightliner financial, your truck can work for your business from day one.
