Steel Mounting Brackets

Ladder Bars and Hair pin radius rods can be installed straight along the chassis rails or angled towards the centre of the chassis to allow for the differential to ride up over bumps in the road with out binding up the rear suspension arm bushes.

However one of the problems when installing a ladder bar supported rear end is that not all of us can cut out the floor pan like a tubbed drag car. Add to this the array of different chassis and floor pans with a different height step up for diff clearance, from early hot rods to mono construction muscle cars to pick up trucks and 50’s lead sleds and 60’s yank tanks, of which dimensions can lead to some hair pulling and much garage swearing late at night when a mass produced ladder bar kit just does not fit.
 
The problem is more in trying to get the ladder bar or hair pin radius rod to sit level at ride height and attach to the diff and to the car in a clean and functional way. All chassis shapes are different and the chassis step up dimension at the rear is relative to how far the cabin floor steps down in the middle. Some chassis are relatively flat like a pick up truck or an A’ model chassis and others are really stepped up like an AC Cobra.
 
The above pics shows a rod under contruction fitted with hair pin radius rods to locate the rear axle and a perpendicular to the chassis pan hard bar.
 
What brackets you choose will depend on how you are going to brace the chassis to attach the front of the hair pins or ladder bars to the frame. The diameter of the tyre you are going to run will determine the axle centre line height, then you will have to determine the ride height relative to the body that you are going to run. So please don’t ask us for a standard kit to suit your vehicle …… are you building a custom car or what? . We have a range of custom brackets so you can sort it out properly and if you do not see what you want, send us a sketch and we can make it for you.

We have identical paired brackets that allow you to angle the hair pin or ladder bar towards the centre of the chassis for both the chassis mount and the diff mounts. We also have a range of pan hard bar brackets and we can custom make street legal bushed rod end pan hard bars for the street.

The picture below illustrates the subtle differences between body styles

The critical dimensions of each bracket are shown in a picture under each component listed here in the Kustom Bitz shopping cart.  Our standard diff brackets have 150mm hole centres for the bars and we have diff tube diameters in 64mm, 71mm, 76mm and 84mm which will cover 90% of all Borg Warner, Falcons, Fairlane, Mustang, Holden, Ford 8 ¾ diffs and the popular Ford 9 inch diffs from tank Fairlane, GT Falcon, to big bearing aftermarket diff housings. The important thing to note is measure your diff, because all models are different. The steps we have chosen for our sizes means that there is not much to linish or file off if your diff tube size is close to one of our standard sizes.

differential-ladder-bar-mounts-street-rod-chassis-building

The other important dimension to know is the brackets are set to get either the bottom bar of a typical drag racing ladder bar parallel with the ground OR a typical hair pin radius rod of which should be symmetrical in its installation which typically means the front rod end will be in the centre of height ~ relative to the diff end rod ends. i.e. The front mount position is usually different to a drag racing style ladder bar, because they are different shapes. See diagram on main info sheet above and below.

 

As we stated above the rear diff bracket holes are 150mm apart and the top hole is used as a reference to the diff axle centre line to identify our three sizes. Shape 1 the top hole is 45mm above the axle centre line, Shape 2 the top hole is 20mm above the axle centre and Shape 3 the top hole is 5mm below the axle centre. This give you a 50mm window to play with which will cover most variations, in any case Size 3 places the bars pretty low relative to the diff and it is about as low as you can go with a 15inch diameter rim. NOTE that in the diagram above and below size 3 is shown on the left then size 2 and then size 1 far right. Note that the bottom bracket hole is in the same height position on the drawing and you can see the obvious different positions of the axle centre line. So size 3 places the wheel further up into the wheel well for deep stepped chassis and size 1 is for not so deep wheel wells. The rest is up to you .
 


 
 

If you are installing the bars inline with the chassis rail then use a pair of “SHORT” brackets per side. However if you wish to angle the bars toward the centre of the chassis to meet street registration requirements then you will need one “SHORT” and one “LONG” bracket per side to provide enough angle for you to play with positioning of the bars.

    '67 Toyota Crown Ute - another air ride bagged project

    by kustombitz on 01 Apr 2021
    The Toyota Crown ute is progressing along, the body is fitting the modified original chassis and this is how it will look when it's dropped ... I think it has the right stance ... The framing you can see is holding the upper body together as the floor and lower sections are rusted away and have been cut out, then to be completely refabbed by us.  The frame allows us to lift the body on and off as we please during this stage.

    1940 Ford Coupe chassis BBC 454 L80E 9" and air ride

    by kustombitz on 01 Apr 2021
    Kustom Bitz just completed a 35-41 chassis, stepped up at the rear and a reversed centre X member allow this chassis to sit 40mm off the deck. It runs a Rod Tech IFS, big block chevy and L80E auto, a 9 inch diff with floating hubs, all on modified original rails. Kustom Bitz has developed our own boxing plates that suit the original rails near on perfectly. Original Ford rails are curved from front to back there are no straight sections, so to get something that fits right we had to jig the chassis up and map them out.  This is what we do, when it just needs to be done right to make it a well engineered car.  This allowed us to make a nice transistion for a high step at the rear. We have designed in 6 inches of travel at the back, so this car can have a normal, almost stock ride height then dumped to the max when parked.

    LS Engine swap and custom air bag IFS

    by kustombitz on 19 Feb 2020
    '67 Toyota Crown ute chassis build is going well. Got the LS engine and 6 speed manual box in place and we can use all the orginal serpentine pulleys, brackets etc. The narrow wheel track on the Toyota called for a tailored solution when it came to the front end.  These old Toyotas dont have service parts available any more so the front end had to be changed, so that made a brake upgrade alot easier too. We run R6 air bags from Air Ride sitting at a ride height of 6" for the air bag so got plenty of air volume in them for a good ride quality and a full length travel shock absorber so we get proper rebound tuning, along with a power steering rack.  So at the sill [belly of the car] we get a 5" ride hieght with a 4 inch drop, this thing will look great.

    Double shear brackets - rear coil overs Hot Rod Chassis

    by kustombitz on 30 May 2019
    Recently in Victoria some engineers have called for the upper and lower mounts for the rear coil over shockers to be a double shear bracket.  The thoery is that the bolt has too much twisting force on it and it will break. Well thats why on Hot Rods we use a 5/8" grade 8 bolt in a single shear bracket application to over engineer it so it does not break. A typical OEM application uses a 1/2" bolt in a double shear bracket. However to please the engineer we have thought out a simple plate kit that can be welded in on the upper mounts as you see here to satisfy their requirements and should fit into most applications without too much effort or rework.  We have a lower mount bracket nutted out as well.

    Diff bump stops custom made

    by kustombitz on 08 Mar 2019
    So many hot rod shops don't install proper bump stops.  In this instance we had to rebuild the shocker mounts on the diff as the rear end was bottoming out on the shocker travel becasue it had no properly designed bump stops in place. So the shock absorber mounting bracket was absorbing every bump when the suspension bottomed out, easy to see why both mounts broke. While we were repairing the diff I made a simple yet effective progressive bump stop that is held in place via the U bolts that hold the diff to the leaf springs. It turned out a very successful set up. This is yet another example how Kustom Bitz can sort out problems on your custom car or hot rod, its what we do.

    Torana A9X custom made rear pan hard bar 9" Diff

    by kustombitz on 08 Mar 2019
    Back in the day Group C racing one of the tricks to get the Holden Torana to handle nice and be more predictable in corners was to fit a rear pan hard bar to give much better diff locating than the OEM triangulated 4 bars offered.  However the body, subframe and floor pan at the rear is no where near strong enoungh to concentrate the loads of pan hard bar in any one spot, so it has to be carefully planned and constructed, especially so in a street car like this that we cannot put a full roll cage in. You see in a race car I can place the roll cage in a position to pick up such loads placed on the pan hard bar brackets, but in this situaton we couldn't. The picture above is with the unit installed, keep in mind the car was just a shell so no weight was in it and the rear is sitting high. Once the full wieght of the car is on, it will sit fairly level.  It retains the original triangulated 4 bars however we run PU bushes in the bottom arms and ordinary rubber in the top arms. So the lower arms and pan hard bar do the locating and the top arms have some give so they don't bind with the pan hard bar.

    Hot Rod 38 Plymouth custom panel fabrication

    by kustombitz on 04 Dec 2018
    We have put a lot of time and effort into this 38 Plymouth.  The whole rear lower panel and floor right through to under the seat has been completely hand fabricated and replaced.  The front and rear mud guards have been widened and the shape reworked for cleaner lines, the guard edge now follows the wheel's shape and shall feature a straight edge running board.to clean up those ugly Plymouth bits but still retain some typically Plymouth features like the swage lines. We have basically just fattened it up and made it more curvey.

    Our first wheels up Launch in Vintage Gas drag racing

    by kustombitz on 27 Aug 2018
    First pass for the day in Q1 in Vintage Gas [V/Gas] and we did our first wheels up launch in "Angas" and later in the day ran our best time so far with this combo with an 8.80s for the 1/8th mile track with an ET of 79mph.  The venue was Sunset Dragway which is just outside Mildura in country VIC. It was a 20deg sunny spring day with little wind, an all but perfect day for this time of year.  Great facilities at this venue for grass roots racers like us and they really looked after all of us racers, so its well worth the trip we had a blast. As far as our little 105e Anglia Gasser goes there is still heaps in it yet when a few tech issues get sorted out, but totally stoked at the moment. woo whooo .....

    Custom made fuel tanks

    by kustombitz on 14 Aug 2018
    Kustom Bitz has made a number of fuel tanks in mild steel and then we line them with KBS Coatings fuel tank liner which seals the inside off from rusting.  The beauty of mild steel is we can design it in such a way that it does not need strapps becasue it doesn't fatigue in a way like alloy or stainless steel with similar brackets.  It does not have to be perfectly square either, most of the tanks we have made are odd shapes to maximise the available space to gain maximum fuel capacity. The other advantage of mild steel is that in an accident it is less likely to split, even along the welds becuse we hand make them from cold rolled steel which will deform long before it splits and cracks. A custom tank is time consuming to do so if you can fit a cheap mass produced tank in your car then go for it, however if a technical outcome is what you are after then we can assist.

    Swan Hill Dragway in country VIC

    by kustombitz on 01 Jun 2018
    Nostalgia drags were on last weekend at the newly constructed Swan Hill Dragway. The first big meeting had an enourmous turn out of cars, there was some serious race cars there representing all classes. What a venue this track is going to be as they complete the supporting facilites.  Australian Nostalgia Racers put on the event in conjustion with the local Swan Hill Drag club members and it was a credit to all who were involved, I can tell you it is well worth the drive up there ..... just go. We had our Shop drag car that runs in Vintage Gas class, of which we have named ANGAS which is short [obviously] for Anglia Gasser.  This is our test bed for experience in racing and tuning AussieSpeed Performance Parts  We run a 250 6 cyl Ford Crossflow engine with an AussieSpeed AS0216 4brl intake and a double pumper carby, big hyd cam, high comp pushing down through a 4 speed stick to a Hilux diff.  First time out for the new combo and still alot of sorting to do, so the times were down but the fun level was up and over the top. You can view the build of the car here facebook@angliagasser
