FORD F350 HD / E450 Spindle
This replacement spindle is engineered for Ford’s trusted full-float rear axle platforms such as Ford F-350 HD pickups equipped with Sterling 10.25″ full-float rears and Ford E-450 Super Duty dual-rear-wheel cutaways commonly equipped with Dana 80 axles. These drivetrains are valued by fleets for their durability, ease of service, and long parts support history.
Built for rear-end rebuilds on hard-working trucks and chassis cabs, this heavy-duty spindle supports the load capacity and bearing performance these platforms are known for.
