Does anybody know what came with a 60" wide ford 9" rear end. Something pretty common in the junk yards? Thanks.

trucks. try 1970's or so. I think mines out of a 71 and its 60 axle flange to axle flange. 56 and 1/2 or so from end to end on the rear end. You can also use the same length axle on either side with an offset pumpkin in it. Makes the spare axle situation better.

82' ford F150, 60" housing. Just bought two more complete rears, but other than them being 60" do not know what they came out of. Trucks mostly, cause I want the 31 splined ones.

I've read...on this forum...that a 60 is a good place to start with on a metric and to adjust final setup with wheel offsets. I'm goin to run a 3/8 medium banked track.

What kind of car are you running is it a stock car/hobby stock or is one the late model type

The point iam getting at is some people dont relize that if you start with a 60 inch rear end you dont have much room to play with off sets to fine tune your race car

If you start with a 59 or 58 inch rear end then you can play with your offsets a little more cause with your 60 inch rear end a 2 inch offset will sick way out and you can have tire rubb but if you make the rear end a little shorter you can still achive the same thing with a two inch off set but it wont be stuck way out for some one to knock off

I have a 60" in my metric and a friend has a 58" in his metric, I can run 4" offsets in the back with no tire rub and he has to run 3" offsets so his tires dont rub. That gives me one more option than he has. Just something to think about.

The class I'm gunna run is hobby stock(though I usually call them outlaw hobbies because the class has very loose rules, this will be the first year they have a min weight). I was just thinkin about what I've seen that works there. Most cars are camaros that sit really low with wide tracks with the tires hangin out. But I get what you're sayin, I don't want to be breakin lots of parts, and I want to build the car right the first time...so...where can I get a 58" rear.

The best place to get rear ends is a place out of California that uses all new stamped centers and new tubes ( the tubes are the heaviest i have found so them dont have a tendancy to bend) plus they have a seal in there to keep the fluid from going into the axle tubes in the corners starving your gear from oil
Speedway engineering 818-362-5865 www.1speedway.com


Plus fellas i read a article today that most of us dont do we dont put enough fluid in the rear end
They said using the fill-check plug in the front as a full indicator is never enough ( we have a raised plug level in ours) they said you need to run a minium of 1 gallon

You have to be carefull of how much fluid you use. If you get to much you will also have extra drag moving all of that gear lube around. Something to think about.

I feel the need to share this article with you

This goes aginst the nature of just about every driver out there. After all,thick oil robs power right? Like everything else in life sometimes yes sometimes no.
We often see racers use super thin oil in an effort to get less drag but they are hurting there gears and dont know it.
Certainly gears will cut throught light oil more easily, But dont forget that the function of oil is to provide a cushion between gear teeth.
If you run oil thats to light, you hurt your gears and when you hurt your gears you hurt your speed. I hate to remind people of this because it sounds so basic, but sometimes we forget.
Gears are designed to operate with a layer of oil between them that can be just tenths of thousandths of an inch thick.If they don't get that thin layer of oil, you end up with metal-on-metal contact,and power instantly goes down the toilet.Study what you are doing and keep an eye on your parts, they will tell you what you need to know.If you are trying new oils, run a set number of laps,and then take a look at your gears.
If oil is too thin, you will have excessive wear on the gear teeth. Too much friction will also generate heat,and you will see a color usually blue or brown on gears that are polished.
A temp guage also is a way to tell if your oil is too thin,if the oil gets hot, it is stressed,strained,squeezed and mashed, and the temp gets way up there.Use the same type of guage that you use in oil coolers and engines.Oil temp should be close to 200 degrees.

If you look at a quick change rearend its design really keeps the lube around the gears.A 9in isnt like that. There is no seal between the pumpkin and axle tube, if you do put a baffle in it, its still several inches away.Everytime you go in a turn the lube sloshes to the side, if you dont have a baffle or axleseal it goes into the tubes.
Imagine running a gear for a second with no oil, the damage may be minimal, but that damage accumulates everytime you go through the corner.Over time it adds and leads to premature failure.
IT'S A MYTH THAT THE EXTRA OIL IS REALLY A DRAG ON A 9IN HYPOID GEAR.Besides even if it is draggier its still better than running metal on metal, even for a second.
