GN 9" rearend

[claytonisbob]

I'm going to post this to suspension because I post this to those who see a benefit to going with a full floater rearend.

Do many/any of you guys run a GN style Ford 9" rearend with full floater axles? These housings are stocked by quite a few places with threaded housing ends for floater hubs, and GN stuff is so well supported and cheap I don't see why not. Speedway has a kit that had everything but the calipers, brackets, and the center section for like $650. A lot of us are going with the aftermarket panhard bar's anyway, and the width at 60" is pretty in the ballpark of stock if I'm not mistaken. They're 5 on 5 hubs too. I guess the one thing that would be difficult is the parking brake would be hard/impossible to do (not a big deal to me not to have a parking brake).

What are the down sides? The upsides I see are: a simi affordable 9" housing, full floaters are more reliable in case of axle breaking and road racing applications, no brake kickback issues seen with c-clip axles. I've always thought this idea would be great if you wanted to have a couple pumpkins for taking autocross/road racing with some 3:73 gears ect , and another with a spool and some 4:10's since swapping them would be pretty easy.

As long as you run a 31 spline or higher i doubt you'll break a axle.But see what quickperformance.com will cost you they are cheaper then the big names like currie.For rear brakes you can have a parking brake kor3.com has a few kits the cheapest is 676 bucks.Or if you want cheaper i can give you a link to mustang cobra rear disc they are 11 inch single piston with parking brakes.Only downside to that one will be redrilling the rotors.

You'd have to get brakes with weld on brackets that would fit the housing/rotors it's designed for... which are just the grand national brakes, which should be pretty cheap and plentiful.

The grand national used alum drums,For road racing i would run rear disc for for the extra braking.Kor3 has some bolt on kits for a a 9 inch housing or the mustang cobra you can get the brackets that bolt on the rest you can get any auto parts store.

http://www.mustangsteve.com/cobrabrakes.html he only sells the brackets but everything else auto parts store,You will have to redrill the rotors tho.

Using 5 x 5" hubs is easy. get the speedway, or howe, or ..... steel hats, and use 12" rotors. Use a weld-on caliper mount for mid-size GM calipers and use the cadilac caliper with E-brake. Works great.
