Kustom Bitz has the parts to custom bend up a blank engine tube for you to fit in your home garage or we can set the engine up for you in our workshop in Croydon POA.  From a quick sketch we can see how feasable it is because there are always some limits depending on the tooling we have on hand, or it may need to be fabricated or laser cut.

So by now you would have seen a wide variety of prices on Ford 9 inch diff components, housings and axles. So of the cheaper stuff who's is up to scratch, a good question and one which comes up alot in my workshop and I would like to address it here. Honnestly you will never really know until you break it, and there in lays the problem, are you prepared to spend less and end up with problems? If I supply a 9" diff for your hot rod or custom car I dont want issues with it, I will buy the best parts from reputable suppliers that support me and I trust that have good gear, I am not interested in making money on those components or being the cheapest supplier, I want to be known for good work and putting together an accurately built housing and link set up for your car.  I do buy the best axles and make no money on them, hence I recieve some flack around the traps as you would imagine. The usual statement I hear is "it's not a drag car ..... etc. etc."  Yeah so why did Ford put so many 9 inch diffs in un modified production passenger cars. You know it is a costly process to produce good metalurgy and it takes experience to repeat it time after time in production. Well produced parts last the distance, while other parts don't.  If you get a chance pick up and hold one of those cheap aftermarket 9" diff housings along side a regular Ford housing, they will be alot lighter and hence weaker, more suseptable to fatigue, bending etc. A Borg warner diff will have less flex than these cheap units.  The main concern when selecting parts for any road car is long term fatigue, you should know by now that cheaply produced metal fatigues real quick and can therefore break, it is no more complex than that.  For me it's a no brainer, don't skimp on parts. Rant over.

This 32 Ford chassis we used an Extreme 9 inch diff housing and one of their floater kits so we can run a 10 inch rim safely on the street.  We get the bare housing in and using our own develpoed diff welding jig we fit the floating axle kit, set up the brake caliper brackets, parrallel 4 bars and pan hard bars using Kustom bitz made parts which are all available here on our website.  This set up looks the ducks guts in any hot rod or custom car, the Extreme rear end is quite rigid and much stiffer and stronger than a conventional pressed steel type, OEM style, round back housing.

Shown here in this photo is one of our custom centre X member kit to be installed in an early 1950's pick up truck chassis. Supplied as shown with pre notched pipes and bent tube for tail shaft clearance as well as the rear transmission mount. 42mm x 3.2 wall mild steel will provide the rigity needed for a modified early car chassis to pass beaming tests etc.  Supplied as an unassembled flat pack as shown these are a pick up only item. POA.

At this years ASRF street rod nationals I saw a neat chassis on display that had our exhaust hanger brackets fitted to it.  I love seing our products being used in different ways to achieve a good result, well done.

This pic shows one of our Hot Rod IFS units before it left the workshop.  This one was set up to take an R6 air bag on each side, have full shocker travel for ride tuning and have a total of 5" of drop from ride height.  The problem with conventional coil over style air bags is the limited travel, typically you only get half of this drop which does not have the desired dramatic effect that this design gives. However this can not be designed as a bolt in unit, the chassis has to be altered to suit the IFS unit.  I am running a Flaming River manual steering rack, the Straight arrow model.  Here at Kustom Bitz we can set these racks up properly and modify them when correct geometry requires it.

Shown here is a 4 bar brackets I have designed to locate a 9inch diff with coil over shocks on the rear end of a lowered 1969 - 72 model F100. I use big rubber bushes oversize 4 bar tubes and utilise the leaf spring forward mounts to keep chassis modifications limited to the rear end notch for diff clearance. I will post some more pics of the finished set up soon, it has worked a treat. Kustom Bitz can custom make 4 bars to suit any application. All custom work is done at an hourly rate.

This 34 Ford Tudor at the Melbourne Hot Rod Show this year features our Lakes Hot Rod Parts IFS by Kustom Bitz. Stainless steel one piece upper and lower control arms and stainless steel stub axles and steering components. It looks a treat now that the car is finished, congratulations to the owner for a job well done.
