Introducing our revolutionary
Full Floating 9" Rear End System
This system features:
11.75"x.810" rotors, 'Kelsey Hayes' 4 piston calipers
with Porterfield pads,
no parking brake. Fits 15" aluminum wheels or larger.
When building a maximum performance street or track car you find all
sorts of weaknesses in the stock components. One major component
that desperately needs attention is the stock rear end. Its
semi-floating design allows the axles to move back and forth slightly
on square roller bearings. If you want to run serious rear brakes in
the form of a fixed caliper, you'll find this movement pushes the pads away
from the rotor when cornering, only to really get your attention when you
need to brake for the next corner. You end up pumping the pedal or
have a very long pedal as you have to move the pads back to the rotor face
before any friction can occur and slow the car. Not an enjoyable
feeling. A much more preferable situation is a pedal that is in the same position every
time and having amazing stopping ability each and every time you step on the
brake pedal. Brakes are not optional!
One other major safety concern with the stock rear end housing and
axle design is that if you break an axle in the right spot, you can loose
a wheel! Think about it. All that holds your wheel on is the
flimsy stock bearing retaining plate and the bearing being pressed onto
the axle. If the axle breaks on the outboard side of the bearing or
the bearing fails the wheel is able to fly off in a direction you don't
really want it to go! With today's sticky tires and modern
suspension designs exerting way more loads onto components that were
originally designed for skinny bias ply tires, we should all take a long
hard look at these critical safety areas of our cars.
Our Full Floating 9" Rear End System eliminates pad knock back and
removes the safety concern of breaking an axle. The
weight of the car now rides on the housing, not the axle like the stock
design.

Our
Full Floating 9" Rear End System includes:
- Brand new, heavy duty 9" housing with full 3" O.D. axle
tubes. Brake brackets, leaf spring saddles, Watts Link and/or
trailing arm brackets come installed and are beautifully
and professionally Tig welded, then the housing is straightened to ensure
trueness. Housing is powder coated gloss black and looks almost too
nice to install out of sight under your car!
- Housing includes a baffled -6AN vent tube on the LH
side, fill, level and drain plugs and a 7/6" stud on the LH axle tube for
brake flex line mounting.
- Solid premium alloy steel, double heat treated, 31 spline, fully
polished axles. Axle installation and removal tool included.
- Axle tube seals. These install in the housing to keep
gear lube from migrating down the tubes and keep it in the center section
of the housing.
- Forged 4140, heat treated steel hubs with races pre-installed.
- Heat treated drive plates.
- 3" long 1/2-20 ARP bullet nose wheel studs pre-installed into hubs.
- Massive tapered roller bearings, keyed washer, nut and lock ring.
Special spindle nut socket included.
- 11.75" x .810" heavy duty rotors mounted to steel rotor adapters.
Packages under most 15" aluminum wheels without wheel spacers.

Porterfirled R4-S pads.

Critical dimensions you should know about our housing:
- For 65-66 Mustangs our system is built 57.25" wide measured from
wheel mounting surface to wheel mounting surface. For 67-70
Mustangs we build them 59.25" wide. This measurement is taken
from the drum or disk face your wheel mounts to. If you need
it wider or narrower please contact us. Please note that
custom ordered housings are non-returnable. If you order it,
you own it.
- Leaf spring pads are installed 43" on center which is the stock
location for 65-70 Mustangs. If you need them in a different
location, please contact us.
- Leaf spring pad to pinion angle is 3 degrees up. If you
need a different angle please let us know.
- Pinion is located 3/16" to passenger side which is standard
for 65-70 Mustangs. If you need it
offset one side or the other please let us know.
- A 7/16" x 1-1/4" long stud is welded onto the top of the drivers
side axle tube 17" in from the wheel mounting face to enable easy
mounting of brake line blocks (please see picture above).
- A -6AN vent tube is welded on the drivers side of the housing
(please see picture above).
- Standard hubs use the Ford 5x4.5" bolt pattern. Other bolt
patterns are available.
- Please note that if you decide to change any of our standard
dimensions the housing is considered custom and is non-returnable.
Please measure twice and order once.
System is shipped ready to install. Simply pack the wheel
bearings, install the hubs, run brake lines, add your center section, install the axles, fill with fluid and its ready to run! Our housing is highly
customizable and can be made wider/narrower, shipped with or without
leaf spring saddles, painted or bare. If you have a custom
application let us know and we will try our best to accommodate you!
All systems are built to order, please allow approximately 6-8 weeks
build time.
