• Integrally Forged Kingpin: Solid 1" king pin is integrally forged with upper raceway using SAE-1050 quality grade steel. Used with a slotted nut to allow for proper bearing adjustment whenever necessary. Designed to be virtually indestructible!
• Hot-Forged Steel Construction: Top plate, yoke base and bearing retainer are hot forged using SAE-1050 hardening quality steel. Raceways are precision machined for 3/8" hardened chrome steel load bearings and tapered thrust bearing.
• Flame-Hardened Swivel Raceway: All bearing raceways are flame hardened to extend service life, reduce brinelling from shock loads, and to generally improve swivel performance.
• Continuously Welded Fork Legs: Side forks are made of 3/8" thick steel plate and are continuously welded on both sides for added strength.
• Locked Wheel Axle: Steel axle bolt is locked in position with indexing lance in side fork to prevent unwanted movement.
• Special King Bolt Assembly: Utilizes a special SAE-8640 hardened steel king bolt to meet the severe and rugged demands of automotive line assembly. Used with a slotted nut to allow for proper bearing adjustment whenever necessary.
• Completely Heat-Treated: All metal parts, including wheel, axle bolt and nut, are heat-treated to a specific molecular depth and Rockwell hardness.
• Optional Wheel Bearings: Drop forged wheel is offered with either straight or tapered roller bearings. Metal seal is also available with straight roller bearing.
