I have a 7.5 in with a Ford Performance or whatever it was called traction lock and 4.10 gears that I bought new and installed. Its in an 82 hatch with a carbed 302. Its been 7.80 in the eighth, with 1.8 sixty foots on drag radials. Seems fine.
The axle has been in there since 2003 or so, on BFG Drag Radials, significant number of passes, a half dozen or so sprayed. Its a C4 trans with a 2500 stall.@Rcdgl how many trips, how long and what type of transmission in this car?
That does not sound nearly as fragile as many here think.The axle has been in there since 2003 or so, on BFG Drag Radials, significant number of passes, a half dozen or so sprayed. Its a C4 trans with a 2500 stall.
Power doesn't kill a rear end. Abuse does. Putting a set of drag radials, or slicks on the car will most certainly cause that thing to fail. If a 7.5 diff was up to the task of handling 300 ft lbs of torque, there was never any reason for Ford to upgrade it to an 8.8.
If you street drive the car on street tires, and you don't act a fool, the rear will probably never give you any trouble. Travel Distance will not affect it at all.
Conversely, if you do ever plan to drag race the car on any tire better than a street tire, you are setting yourself up for failure. It may, or may not happen immediately, but don't kid yourself.
Yeah I guess..you can also ride a mtn bike along the spine of a really, really treacherous mtn. and survive too.That does not sound nearly as fragile as many here think.
