A railroad car bearing adapter assembly configured to be employed in combination with a high warp restraint truck (with or without an auxiliary or original warp restraint system), and including a low profile thickness and relatively longitudinally narrow roller bearing adapter, a low profile adapter shear pad with a shear stiffness in a range of 85,000 lbs/in to 125,000 lbs/inch, and side wear pad that in combination total clearance in a range of 0.09 inches to 0.36 inches between the side frame thrust lugs and the adapter with the side wear pads. This overall combination reduces wheel wear and damage, reduces fuel consumption, reduces the need for railroad track repair, improves high speed stability and curving performance for both empty cars and loaded cars, provides more truck stability under a loaded car in shallow curves and while encountering certain perturbations, and provides optimum curving performance that enables the axles to better align with curves of relatively high degrees.
