The Eaton Detroit Locker 250S-98 or 250S98 is a No-SPIN locking differential designed for Dana IHF155 axle applications on International Harvester vehicles. It fits a 1.85-inch axle shaft diameter and uses a 36-spline gear tooth count. Verified vehicle usage spans a wide range, from drag racing and circle track to rock crawling, extreme off-road, light trail, sand sports, street and muscle builds, and work truck or towing duty. That breadth of rated usage makes it a workable choice across both on-road performance and demanding off-road service. Call us to confirm proper fit for your specific axle configuration before ordering.
