4:56 Ring and Pinion Info

CHRYSLER

PROBLEM: CHRYSLER: 9.25", 12 Bolt Cover, 4.56 and Higher.
I bought 4.56 gears for my 1/2 ton pickup, but I cannot get the cross pin into my carrier.
SOLUTION: It does not matter whose gears you use. You will need to modify your cross pin to use a 4.56 or higher gear in your vehicle. This applies for open differential, Auburn and Eaton differentials. The pin will need to be cut at an angle opposite the bolt hole. Most do this on a grinder to slightly flatten one side of the pin making clearanace to the ring teeth allowing the pin to slide in. Because every manufacturer is different, no measurement is provided.

FORD

PROBLEM: FORD: 7.5", 10 Bolt
I bought 4.56 gears for my early fox body (pre-1986) and I cannot get the cross pin into the carrier.
SOLUTION: It does not matter whose gears you use. You will need to modify your cross pin to use a 4.56 or higher gear in your vehicle. This applies for open differential, Auburn and Eaton differentials. The pin will need to be cut at an angle opposite the bolt hole. Because every manufacturer is different, no measurement is provided.

GENERAL MOTORS

PROBLEM: GM: 7.5"/7.6", Bolt Differential, 4.56 and Higher.
I bought 4.56 gears for my F-Body and I cannot get the cross pin into the carrier.
SOLUTION: It does not matter whose gears you use. You will need to modify your cross pin to use a 4.56 or higher gear in your vehicle. This applies for open differential, Auburn, Eaton, and Gov lock differentials*. The pin will need to be cut at an angle opposite the bolt hole. Because every manufacturer is different, no measurement is provided.
* If your F-Body is a SS or WS6, you have a Torsen differential. This uses a block and paddle system that cannot be modified. However, SLP has a block and paddle kit that will allow you to use a 4.56 and numerically higher ring and pinion.
