Pre Loved Detriot 10 spline Auto Locking Differential plus LAND ROVER 4.7 Ratio CWP. PL105

Here we have a really nice low mileage (been in storage for years) Detriot 10 spline 'AutoLocker'.

This has been stripped and rebuilt into a Split Nose Series Casing (fits Series 1 2s or 3s) with a 4.7:1 Ratio CWP (Standard Series Ratio)

We have kept everything on the outside that is 'Visible' Original with new lock tabs etc even repolished original bolts + new dust sheild and new drive flange and seal etc, but on the inside we have upgraded the CWP Bolts to FTC5150 12.9 Grade for more strength being it's now a Detriot !.

We have also upgraded the Carrier cap bolts again with 12.9 Grade bolts and Nordlock washers - again for additional strength - Detriot do Grip you know !!

Rarely do we get these units in this sort of condition, a really nice unit for not a huge amount of £s

If you have a desire for a really nice new diff giving you some serious Grip in your 10 spline rear axle (NEVER EVER FIT IN A FRONT !)..then ... here you go !!

Please Note : This is also listed on our 'All things Series' Page - we do only have this one !!

NO Exchange unit and No Surcharges etc required

An absolutely fabulous fully rebuilt 10 spline Series Split Nose with brand new GENUINE LR 4.7 CWP Gearset

We bought in a huge amount of Brand new GENUINE Land Rover 4.7:1 (Series LR Ratio) Gearsets, which were supplied to the military with unbelivable anti corrosion packaging (see photo !) So, to expand on what this unit is :

1st, this is a early 'Split Nose' Casing

These are a 2 piece casing, the benefits are that they are better quality (we actually did a video of all the various LR Long Nose casings from the 1st in late 1948, right through all the
differing varinats - and guess what ?... Yup, they simply got WORSE as the years and changes occurred, with obvious cost cutting being at the top of the planning list....)
Sooo, these 'early casing are stronger, have a lovely brass filer plug that you can use to get oil in to the axle way easier than the rear axle case pan filler :O) - and also the 'Nose'
of the casing has a bolt on / removable nose piece holding the Pinion seal, which is another lovely touch - which LR deleted quite quickly !

This unit - even with the nose bolt on bit - is the same (just better) than the later 'Full Size / one piece' type casing - and will fit ANY Long nose series LR axle

that requires a 10 spline center, and a 4.7:1 CWP ratio (so not early Range rover - nor early 10 spline 90s etc - whilst they are 10 spline they are not the Series 4.7s they are 3.54s )

This basically has had all new bearings, a BRAND New genuine LR CW&P in 4.7 Ratio, and has been rebuilt using all original parts like the Tablocks on the CW Bolts and Nose, lock wire on the
carrier caps, we have reused all the original bolts having ultra sonic cleaned them and then repolihed them, new Original Drive flange new seal, and so on.

The idea of this unit is that it is pretty much now as it was when it left the factory, totally original spec build, so if you are looking for serious originality - then this ticks every box

We have a 2nd one of these planned - which may be listed below - this will have all modern 'Upgraded Bolts' etc, where you are looking for better / stronger build spec, and way less originality

As for this crown wheel and pinion - take a look at the care the unit came packed - says much about old school qualitity and the insistance of the military to having it wrapped properly !
if only such care and quality control existed in 2026, you wouldn't belive how LR Genuine Crown wheels are shipped to us - we can't even belive it !

And even more amazingly - you can still buy new genuine LR Series 4.7 CWPs gearsets - (The pattern ones are all absolutely awful quality) and the Genuines are around £600 + VAT !!!!!
So, here you go, a properly rebuilt Series Differential, new 4.7:1 series Genuine Crown Wheel and pinion, built to original specs - and will be (poosibly the only) silent unit on your 4x4.

No Exchange unit and No Surcharges etc required this is an outright purchase price.

Be VERY careful if you buy this - Make SURE its what you want !! 1949 Super Long Nose

WARNING - Yes it is a 10 spline 4.7 Ratio diff - BUT - this is a Rare 'Super Long Nose' from circa 1949 - which is absolutely unique to ONLY early - VERY EARLY 80" Series 1s

The identifying difference is the very long Drive flange, but as diffs go so much is internally unique to these units - made by LR for less than 2 years...

So, unless you know what this is move on and do not but it, not suitable for any LR Post late 49, and defo not series 2 or 3 etc...

Condition wise, well considering its nearly 80 years old its pretty good, plan were to completely strip and refurbish, but we were so busy we never got around to it, and also
if I am brutally honest I sort of forgot I had it , maybe 11 years back when I bought it !

Its the 4.7:1 Ratio, and the entire diff feels pretty smooth, and the CWP gearset looks pretty damned good too, considering the price for the pattern ones new I would myself cleaned it up
and gone with it, otherwise the price would have been £1000 on top for the CWP over just bearings and whatever else.

But - Its all there absolutely complete and looks better in the flesh than these 2 x pics !

Finding one of these that isn't an absolute basket case is tricky at best - and to be honest I have priced it pretty damned low to sell.....

It now sits on my office desk, and I admire it every time I go to do work, I'll keep it until it sells, hell I might even want to know plans for it - more an adoption than a sale !! .....

And no, .....I don't expect an exchange unit LOL ....outright purchase...... and I am sure this will make someones day when they find it :O)

And...Be VERY careful if you buy this too - Make SURE its what you want !! 1949 Super Long Nose

WARNING - Yes just as the one above - this is a 10 spline 4.7 Ratio diff - BUT - this is a Rare 'Super Long Nose' from circa +/- 1949 - which is absolutely unique to ONLY
early - VERY EARLY 80" Series 1s whilst it would fit in the casing of later Series 1 2s or even 3s the prop length would be wrong and the actual unit incorrect ..it's a bit special !

And, as above the identifying difference is the very long 'Drive' flange, but as diffs go so much is internally unique to these units - made by LR for less than 2 years...

So, unless you know what this is move on and do not buy it, its for these really early axle 80' 4x4 LRs not suitable for Later Series 1s 2s or 3s etc...!!

Condition wise, .....well this is a real oddball unit in itself .!

We bought this is a LONG LONG time back - probably well over 16 years ago !

The really strange thing about this unit, is the casing itself barely has any - if any - original paint left on it ! The 'nose cone' is still the factory grey finish, and if you just looked
at the exterior you wouldn't be that impressed at your 1st glance at all........We weren't either.

But, when you look at the insides - thats a completely differing view !.

The oil is like new, the Crown Wheel & Pinion do have some minor marks and minimal pitting in places, but - it's clean and super shiney ! - so to are the internal differential gears
themselves and even the cross pin shows the original copper coating - it really is that clean....

Its not a silent differential when you rotate it, but these units are weird in that they have ZERO preload due to the design and never silent plus its 80 years old and I would say totally
original, it is however super super smooth, no tight spots.

When we bought it the plan was to at some point rebuild it....and then here is the 'quandry' we had ...

As a unit its I would say more than good enough to just be fitted and used.

As a differential company at the time we thought ...well,.... we could sell it as it is maybe, ...or we could rebuild it....

'Pros' to rebuiding it are that it would then be a top of the draw super condition 'As New' rare diff, but, then again the 'Cons' are that these are very expensive to build - VERY - so the
price woiuld be horrendous if all new bearings etc, and where do we stop ?....

A new Crown Wheel & Pinion is circa near £1000, so add in all new very expensive rare bearings a seal and a new drive flange and some labour - and you start to see the dilema ....it would just be bonkers money and actually when you look at this diff 'As is' its near Sacrilege to in effect destroy / throw away parts that still have life
more than left in them, and we could offer this unit 'as is' for a fraction of the cost rebuilt, and save it - all at the same time.

Add into the equation we were super busy we never got around to it, so we oil sprayed it wrapped it and popped under a bench and its only now come back to see the light of day now !

As a HUGE Compromise I have fitted a brand new Drive Flange Oil Seal (I had new old stoc so hey ho eh ... ) LOL, and that's it nothing else has been done to it.

The plan now is to offer this 'As Is' and the new owner can decide if and when they want to do anything to it, be it fully rebuild it, just repaint the outside - or something inbetween
or absolutely just nothing fit it and enjoy it ! - Either way its up for grabs and we have made OUR decision as to what WE are doing with it !!

We can send more pictures if you would like, the 3 x here give you the idea - the outside ....vs the inside !

Outright Purchase - No Exchange no Surcharges - simple Outright Purchase .....someone is going to be very happy with this find !!

BRAND NEW Old Stock GENUINE Land Rover Series 4.7 CWP set

The Series LRs CWPs being 4.7:1 Ratio means if you need a new one the options are limited.

As Differential builders we know that there are no decent 'pattern' 4.7 CWPs out there, we have tried them all.
Simply put - they are ALL appalling quality mainly made in India, then rebranded and sold for differing prices by various retailers across the UK !.
They are all nasty !

However, we have now a number of GENUINE LR Factory 'New Old Stock' Units.

These are all as in the pictures, some are 'Military issue' from LR to the Military, and some are in Rover / Leyland / Unipart ! Boxes etc. All are Genuine brand new LR Units - boxes may vary LOL !.

As such these build really well, vs the pattern stuff (yes.....we have tried ALL the avaiable pattern gears - just don't is our advice ! ).

So, as to be crystal clear - We have put a few pictures up of the various types, as said all are Genuine LR issue, but the boxes etc vary between them, if you just order one / two we will send whatever is next on the shelf.....

But if you REALLY want one particular box for whatever reason ...then ring and advise which one you fancy ...either before of after you have bought and you can have whichever you wish for if that helps !

If you want a really good quality 4.7:1 CWP for your Series you will not regret investing in these !

BRAND NEW Old Stock GENUINE Land Rover Series very Early 4.7 Version with the additional Ground Shaft Tapered Hole on Crown Wheel

Not all the 4.7 Series LRs CWPs are eaxctly the same !.

When LR changed the ratio from the 1st differentials - the 4.88:1s to 4.7:1s the early version of the new ratio has an 'Extra' hole in the crownwheel and the Center body, these take a special 'Ground Pin' and nut and were made to improve the centering of the 2 units. It wasn't for long - as they soon 'Deleted' this hole - probably to save money !.

If you are rebuilding an early 4.7 Differential and have this version it is a higher quality solution. You can use the normal 10 bolt type - as above, but not the other way around.
