Ford attached an aluminum tag to one of the carrier bolts at the factory to aid in determining the gear ratio and build date of the 9-inch rear. There are two rows of numbers on the tag.The first row will show five digits that designate the Ford part number for the axle.The second row will have 9 or 10 digits.
2012–Present Ford F-150 (Super 8.8, depending on engine and other options)
How do I identify a Ford 8.8 rear end?
You can identify the Ford 8.8-inch rear by its rear cover. It has a thin metal or plastic 10-bolt cover, and the bolts are 7/16-inch thread. The cover is not quite square, measuring about 101/2 inches high by 11 inches long. The 8.8-inch pinion shaft is 15/8 inches and has 30 splines.
How do I identify my Ford rear differential?
The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials.
Is a Ford 8.8 the same as a Ford 9-inch?
A Ford 9-inch has a ring-gear diameter of, you guessed it, 9 inches closely followed by the 12-bolt at 8.875, with the Mustang rear at 8.80 inches. Another strength consideration is pinion-shaft diameter. Here, the 8.8 and the 12-bolt are identical at 1.625 inches and in fact use the same pinion bearings.
How do you determine differential size?
Ring gear diameter can be a helpful way to identify which differential you have. The ring gear diameter is measured across the face of the gear. To obtain the ring gear diameter, simply place a tape measurer across the gear. This can be tricky if the ring gear & carrier are still in the housing.
What gear ratios are available for a Ford 8 inch rear end?
Original gear ratios range between 2.79:1 and 5.43:1, and aftermarket replacement gears are available for many ratios as well. Like the 9-inch, the 8-inch uses no carrier breaks, meaning you can put a 5.43:1 ring and pinion in a 2.79:1 rear without changing to a smaller differential carrier.
What gear ratios are available for a 9 inch Ford?
Choice of Gear Ratios: 2.50*, 2.75*, 3.00, 3.25, 3.50, 3.70, 3.89, 4.11, 4.30, 4.56, 4.71, 4.86, 5.00, 5.14, 5.29, 5.43, 5.67, 5.83, 6.00, 6.20, 6.33, 6.50 NOTE: 2.50 and 2.75 are take out gears.
What size rear end does a 1966 Mustang have?
65-66 Mustangs come with the 7.25″ rear end, non-removable carrier.
How much does a Ford 8 inch rear end weigh?
A typical 9-inch tips the scales at around 205 pounds; an 8-inch is around 160.
How much does a Dana 60 axle weigh?
However, a rear Dana 60 axle usually weighs about 400 pounds, a front Dana 60 will weigh about 500 lbs, and the Dana 70 is similar in weight to the 14 bolt.
Which is stronger Dana 60 or Ford 9?
The Ford 9-inch pinion is mounted lower in the carrier and has the greatest hypoid offset, which causes it to consume more power to drive it than the Dana 60 or GM 12-bolt. The Dana 60 has so much mass it too consumes a lot of power to drive (although many say it feels slightly less than a 9-inch Ford).
Is a Ford Dana 60 the same as a Chevy Dana 60?
If there are 7 bolts, then you have a GMC/Chevy or Jeep Dana 60 axle. These axles are all exactly the same. If there are 4 bolts, then you have either a Dodge or Ford Dana 60 axle. These two axles are not identical.
The main advantage a Dana 70 front axle has over a Dana 60 front axle is better gross axle weight ratings. There are three pinion offsets for the Dana 70 rear axle. 1/2 inch, 5/8 inch and 31/32 inch offset. The first Dana 70 axles had a 1/2 pinion offset and were found in Dana 70HD’s as well.
Is a 14-bolt A 1-ton axle?
The 14-Bolt Is The Ford 9-Inch Of 1-Ton Trucks
Every diesel-powered pickup sold in the United States for the last 10 years has a full-floating rear axle.
What trucks have Dana 70 axles?
The Dana 70 front drive axles used in the Chevrolet Kodiaks and GMC Topkicks also had these features. This axle was standard for the Big Three (automobile manufacturers) dual rear wheel trucks until 1985, when Ford started using the Sterling 10.25 rear axle.
How much weight can a Dana 70 handle?
A Dana 70 can have a weight rating of up to 10,000 pounds, but 8,000 pounds is much more common. A 14-bolt can have up to an 8,600-pound GAWR. The greater the load-carrying capacity of the axle, the greater the strength.
