Narrowed 8.8 rear end

Recommended Posts

This started as an 8.8 posi rear end out of an explorer.

this was narrowed for a friend of mine to go into an older car. He gave me the dimensions he needed for width and pinion offset.

steps.

axles, carrier and gears were removed and the housing was pressure washed.

fixture bushings were installed in the carrier location.

hydrolic shafting was used for an alignment bar.

9” axle ends from a torino were used so the rear end could be converted to use 9” axles and still retain the Explorer disc brakes.

Nice, what the width? From outside hub to hub where wheel mount? I'm gonna need similar deal for a Rambler next year.  I don't need 9 inch.  From what I gather a lot of folks get extra short axle and just cut the long side down on the tube.

The wider he gave  me is just a little narrower than a 65-6 mustang and the pinion is basically centered.

yes the home grown version is to get a spare short axle and narrow the one side. That works if it happens to be the width you need .

i have a couple spare short side axles now so let me know if you need one.

 

i prefer to convert to the 9” axles. It allows me to make it whatever width I want it and eliminated the C clips.

i have done several of this type conversion for guys that drag race or road race. For the drag racers it is like a C clip eliminator kit but those kits say you cannot road race with it and recomend against driving on the street.

for the road racers I have seen the stock axles get mushroomed on the end as there is a little play with the C clip and under hard use it can pound out the end of the axle

This won't have a bunch of power.  As of right now I have a 4.6 out of a crown vic.  I've installed the mustang ii front end.  Got a few things left then will sit the motor in loose and work on steering and brakes. If those start to become to cobbled I'm gonna go with a 302 or 350.

I have a 8.8 from a Ranger pickup ,has a brand new posi but has somthing like 456 gears ,i will not be using it .I know the posie was the best that could be bought and has only a very few hours on it because the guy used it as a pre runner and is the crew chief for a race team in Vegas .

There should only be a 1/4" difference between a late 90s Exploder and the 9" in a 1969/1970. The pinion  is offset to passenger side about 3". If you lower the car, it'll probably hit the transmission tunnel.

I know of a guy that pushed out the axle tubes and swapped sides to center the pinion. If not lowered, hopefully not an issue.

I'm planning on doing this. Where else can you get 3.73's, discs and posi for $150? From my homework. Hoping anyway. Yeah. posi needs rebuild, so that's another $100.. as will probably be brakes, but still way cheaper than finding stuff for the 9" :)

The only true way u can center the explorer pinion is cut 2' off the long side and add 2" to the short side. Even if u cut the long side down to use another short side axle it will still be out of center 1" to the driver's side. Some folks don't mind tho and cut the short side down or just use as is. I centered my 8.8 by cutting 7" off long side and 5" off short side then reversed them and welded back on. Of course had to have custom axles made. I thought of Rsanter Idea later and if I were to do it again is what I would do.
