At 27.18 inches in length, YA F8-28-27.18 fits the inner shaft position in this classic Ford application. The 1541H microalloy construction provides improved tensile strength and fatigue resistance compared to standard 1040 carbon steel replacement shafts, making it an ideal upgrade or restoration part for Ford muscle cars, compacts, and trucks from this era. When the original shaft is cracked, worn at the splines, or has been bent by track use or off-road abuse, YA F8-28-27.18 provides a direct replacement with a strength improvement over OE specifications.\u003c\/p\u003e\n\n\u003ch4\u003eFeatures and Benefits\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for the Ford 8 inch rear differential with 28 splines in 1968-1971 2.8L applications\u003c\/li\u003e\n  \u003cli\u003e27.18 inch inner shaft length for correct fitment\u003c\/li\u003e\n  \u003cli\u003e1541H microalloy steel for improved strength over 1040 carbon steel replacements\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined splines for accurate differential side gear engagement\u003c\/li\u003e\n  \u003cli\u003eCorrect OE-style bearing surface dimensions\u003c\/li\u003e\n  \u003cli\u003eIdeal for restoration, street, and mild performance applications\u003c\/li\u003e\n  \u003cli\u003eClassic Ford compact and intermediate vehicle application\u003c\/li\u003e\n  \u003cli\u003eBacked by Yukon Gear manufacturer limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1968\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eVarious\u003c\/td\u003e\n\u003ctd\u003e8 inch rear differential, 28 spline, 2.8L engine application\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1969\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eVarious\u003c\/td\u003e\n\u003ctd\u003e8 inch rear differential, 28 spline, 2.8L engine application\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1970\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eVarious\u003c\/td\u003e\n\u003ctd\u003e8 inch rear differential, 28 spline, 2.8L engine application\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1971\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eVarious\u003c\/td\u003e\n\u003ctd\u003e8 inch rear differential, 28 spline, 2.8L engine application\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eYA F8-28-27.18\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e883584119951\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAxle Housing\u003c\/td\u003e\n\u003ctd\u003eFord 8 inch (1968-1971 2.8L)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSpline Count\u003c\/td\u003e\n\u003ctd\u003e28\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eShaft Length\u003c\/td\u003e\n\u003ctd\u003e27.18 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eInner rear\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e1541H microalloy steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eYukon Gear manufacturer limited warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat Is Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne 1541H alloy inner rear axle shaft (YA F8-28-27.18)\u003c\/li\u003e\n  \u003cli\u003eSold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eDoes installing this axle shaft affect my factory warranty?\u003c\/strong\u003e\u003cbr\u003e\nUnder the Magnuson-Moss Warranty Act, your dealer cannot void your factory warranty solely because of an aftermarket part installation. They must demonstrate the part caused the specific failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Ford 8 inch different from the Ford 9 inch?\u003c\/strong\u003e\u003cbr\u003e\nYes. The Ford 8 inch is a smaller differential used in lighter-duty and four-cylinder applications while the Ford 9 inch is the larger, more popular axle used in V8 Mustangs, trucks, and performance vehicles. Verify which axle your vehicle uses before ordering YA F8-28-27.18.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I confirm my Ford has 28 splines versus another spline count?\u003c\/strong\u003e\u003cbr\u003e\nCount the splines on the stub end of the existing axle shaft or count the splines in the side gear of the differential. The Ford 8 inch was produced in both 28 spline and other configurations depending on the application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a 28 spline locker or limited-slip with this shaft?\u003c\/strong\u003e\u003cbr\u003e\nYes, as long as the locker or limited-slip is designed for the Ford 8 inch with 28 splines. Always confirm the differential internal spline count matches the shaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs YA F8-28-27.18 suitable for track use?\u003c\/strong\u003e\u003cbr\u003e\nThe 1541H alloy provides a meaningful strength improvement over OE, making it suitable for mild performance use. For high-horsepower drag or road race applications, a 4340 chromoly shaft would provide greater security.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat fluid does the Ford 8 inch differential require?\u003c\/strong\u003e\u003cbr\u003e\nUse 80W-90 GL-5 gear oil. For limited-slip differentials, add the appropriate friction modifier per the manufacturer specification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this a C-clip or flange-retained axle shaft?\u003c\/strong\u003e\u003cbr\u003e\nThe Ford 8 inch uses a C-clip axle retention system. The differential must be partially disassembled to remove the C-clip before the shaft can be withdrawn.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are common failure modes for the Ford 8 inch axle shaft?\u003c\/strong\u003e\u003cbr\u003e\nSpline wear from high-torque launches and stress fractures at the spline-to-shaft transition are the most common failure modes. The 1541H alloy in YA F8-28-27.18 resists both better than standard alloy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat warranty does YA F8-28-27.18 carry?\u003c\/strong\u003e\u003cbr\u003e\nYukon Gear provides a manufacturer limited warranty against defects in materials and workmanship from the date of purchase.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n  \u003cli\u003eRaise and support the vehicle safely.
