Evening,

Took delivery of the axle that i'm going to be running on the rear of my next buggy.

Dana 80 diff

ARB EDM'd out to 40 spline

Ouverson 40 spline 300m shafts

Ouverson 47 spline 300m outer shafts with violator joints

Ouverson super 8 hubs and 6 pot brakes

Steering

Come off a buggy in the states and had it shipped over.

47 vs coke vs 14 bolt vs LR 24 vs 40

47 spline = 2"

40 spline = 1.75"

14 bolt = strange 30 spline which is the same as conventional 35 spline = 1.5"

24 spline LR = about 3mm OD made out of plastic

Nice, but I know from experience that the LandRover 24 spl is infinitely stronger and longer lasting than Coke.

I beg to differ on that, i think we'd have more joy welding coke cans together than the LR stuff.

Truck porn too!!!

very nice indeed!

Thanks, not very practical around town but otherwise perfect !

What you gonna drive that lot with?

Not yet got an engine. But will be some form of LS. Circa 500 - 650 hp.

There is also a TH400 on that pallet, which has been fully rebuilt with Coan internals, so should take any power i can give it.

Also an np203/205 doubler on there for transfer.

What diff are you going to run up front Zim? Tyre size? Has the D80 been shaved for extra ground clearance? Are you going to plonk it in the buggy as is, or heavily offset it to one side as is increasingly becoming common practice in the US to optimise the effect of what ground clearance there is ?

For some perspective, 1950/60's Leyland Super Hippo Roadtrains,regularly grossing over 50 tons on unsealed outback cattle roads here in Australia had halfshafts 2" diameter, and they rarely broke. And they were the largest ones I could find when scouring a heavy truck breaking yard many years ago.

The front will be an ouverson 47 spline inner and out shaft, with a 14 bolt drop in diff. Same hubs and brakes as this rear 80. Using a spool - which is why i can run 47 spline inner shafts (can't get an arb to fit them). If a spool is causing issues, then i can drop down to 40 spline and add an ARB. My original plan was to run fiddles both front and back, but have decided to just have them on the rear and stick with a solid front. With hydro steering i am not too fussed about this.

No, not going to shave the diffs. The rear will be fitted as is, minor modifications to suit suspension. The front will be offset to the right.

I currently have 44" boggers to go on, but with different event rules i may well end up running my current 35's or end up getting a set of 40's, and then just swapping wheels for events. The rims will all be 8 x 6.5

I was referring to the stud pattern, 8 lug x 6.5" pcd.

My 16.5" rims fit over the brakes fine as do my 16's. The disc is 13", but the caliper is pretty snug.

Will be built for challenging / off road speed events as they're becoming more popular here and across europe.

that would explain the need for the big halfshafts then !

I think 2" dia halfshafts are a bit overkill if material specification, heat treatment and shaft design were optimised. Difficult to tell from photo of halfshaft on pallet, but the plain section of shaft between splines and Yoke doesn't appear to have had the diameter waisted down to improve torsional flexibility. Unfortunately most US aftermarket shaft mfg's make them like that, which then is cause for questioning material spec etc. They will likely never break in a UK spec comp buggy, but is all that lard really required ?
