This product line emphasizes precise fitment and consistent performance, making it suitable for Ford E-350 Super Duty and Econoline series vehicles requiring vented rotors with floating disc mounting. The 121.65125 rotor maintains strict manufacturing tolerances to ensure proper braking function and longevity.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis vented disc brake rotor features a smooth surface type designed to reduce noise and vibration during braking. The nominal thickness of 1.417 inches (36.000 mm) ensures structural integrity, while the discard thickness of 1.354 inches (34.400 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter measures 13.583 inches (345.000 mm), with an overall height of 4.213 inches (107.000 mm), matching OEM specifications for the Ford E-350 Super Duty and Econoline Van\/Wagon models. The rotor includes eight stud\/lug holes with a diameter of 0.512 inches (13.000 mm) and a mounting bolt hole circle diameter of 5.709 inches (145.000 mm). It does not include an ABS tone ring or bearings, so these components must be sourced separately if required.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on Ford E-350 Super Duty and Econoline models\u003c\/li\u003e\n\u003cli\u003eAddresses brake pulsation caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRestores braking efficiency lost due to rotor thickness below discard limits\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation in heavy-duty braking scenarios with vented design\u003c\/li\u003e\n\u003cli\u003eEliminates noise and vibration from damaged or uneven rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify rotor thickness before installation to ensure it meets nominal specifications\u003c\/li\u003e\n\u003cli\u003eClean rotor surface and hub mounting area to prevent uneven contact\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications on lug nuts to avoid rotor warping\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and hardware\u003c\/li\u003e\n\u003cli\u003eABS tone ring not included; confirm ABS system requirements before installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eCentric C-TEK Standard Disc Brake Rotors are manufactured to meet or exceed OEM standards for fit, form, and function.
