Yukon Gear 1541H Alloy 28-Spline Rear Axle for 1968 to 1971 Ford 8 Inch 2.8L Cut to Fit from 25.5 to 32.87 Inches
The YA F8-28-32.87 is a 1541H microalloy steel rear axle shaft for the Ford 8 inch differential with 28 splines as used in 1968 through 1971 Ford vehicles with the 2.8L engine. Available as a cut-to-fit shaft spanning 25.5 to 32.87 inches in length, YA F8-28-32.87 accommodates a wider range of axle tube lengths within the Ford 8 inch family, making it suitable for custom builds, restoration projects, and vehicles that require a specific shaft length different from the standard inner shaft. The 1541H microalloy steel construction delivers improved strength and fatigue resistance over standard 1040 carbon steel replacements for classic Ford applications.

Frequently Asked Questions
Does installing this axle shaft affect my factory warranty?
Under 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.
How do I determine the correct length to cut YA F8-28-32.87?
Measure the length of the existing axle shaft from the end of the splines to the bearing surface. If the original shaft is missing or broken, measure the axle tube depth from the differential bearing seat to the axle tube end and add the flange overhang dimension.
What tool should I use to cut the shaft?
An angle grinder with a metal cutoff wheel or a cold saw provides a clean, straight cut. After cutting, deburr the cut end with a file or grinder and chamfer the edge to ease installation.
Does the spline end get cut or the bearing journal end?
Always cut the non-spline end. The splines must remain intact and full-length for proper side gear engagement.
Can I use YA F8-28-32.87 in a performance build?
The 1541H construction provides improved strength for moderate performance use. For high-horsepower applications such as drag racing or sustained track use, upgrading to a 4340 chromoly shaft or a stronger rear axle housing entirely is recommended.
What is the Ford 8 inch used in?
The Ford 8 inch rear differential was used in a variety of 1960s and 1970s Ford compacts and intermediates including the Maverick, Pinto, Falcon, and some Mustang applications with smaller displacement engines. It is lighter and smaller than the Ford 9 inch but shares a similar housing layout.
What fluid does the Ford 8 inch require?
Use 80W-90 GL-5 gear oil. For applications with a limited-slip differential, add friction modifier as required.
Is YA F8-28-32.87 a C-clip or bolt-flange retained shaft?
The Ford 8 inch uses C-clip retention. The differential must be partially disassembled to access and remove the C-clips before the shaft can be removed from the housing.
What warranty covers YA F8-28-32.87?
Yukon Gear provides a manufacturer limited warranty against defects in materials and workmanship from the date of purchase.
Installation Instructions
- Measure your existing axle shaft or measure the axle tube to determine the required shaft length.
- Cut YA F8-28-32.87 to the required length using an angle grinder or cold saw. Cut only the non-spline end.
- Deburr and chamfer the cut end to remove sharp edges.
- Raise and support the vehicle. Remove the wheel and tire on the side being serviced.
- Remove the differential cover and drain the gear oil.
- Remove the pinion shaft lock bolt and pull out the pinion shaft.
- Push the old shaft inward to expose the C-clip. Remove the C-clip and slide out the shaft.
- Apply gear oil to the spline end of the cut shaft. Slide into the axle tube and engage the splines.
- Install the C-clip and pull the shaft outward to seat the clip against the side gear.
- Reinstall the pinion shaft and lock bolt to spec. Install the cover with new sealant and fill with gear oil.
- Reinstall the wheel and tire. Road-test and inspect for leaks.

Axles
Upgrading your axles is one of the highest-impact modifications for trucks and off-road vehicles that regularly see hard launches, deep mud, rock crawling, or towing at the limits. Aftermarket axle shafts are manufactured from higher-grade steel than OEM units, delivering greater torsional strength and resistance to fatigue failures that stock shafts cannot handle under sustained abuse. Popular Upgrades Chromoly front and rear axle shafts are the go-to upgrade for lifted trucks and Jeep builds running larger tires with increased leverage on the driveline. Locking differentials paired with upgraded axles make a complete traction system for serious off-road builds. Heavy-duty CV axles for both front-wheel-drive and all-wheel-drive platforms handle the added stress of lowered suspension geometry and high-horsepower applications. When should I upgrade my axle shafts? Upgrade your axle shafts when adding larger tires, significantly increasing engine power, installing a locking differenti...
