Most modern suv's have IRS since they are considered soccer mom trucks and just need capacity and are usually kept on the road for most of their use. Your explorer I would bet has IRS, it gives a smoother ride, does better on turns and better traction. IRS is best for street, off road or uneven terrain solid is better because less moving parts and all around is stronger and can handle more stresses. In a mustang IRS is better all around then solid axle.
