All Things 'Series' Land Rovers - Differential and Parts Page

On all Series Land Rovers, from the very early Series 1 80' with their 4.88 Super Long Differentials, through the following model years of the various 80 inch variants, we are seeing a huge increase and demand for the all Series Differentials inc 2s and 3s. More restorations are being done, and their owners are looking for both quality & originality and a specification in the work they choose to have undertaken.

We are finding that these rebuilds fall into 4 main categories :

And, that's what we can do - and pretty much anything in between. We can restore, rebuild, even upgrade if required your Series Differentials to whatever specification and level you wish to have. We have probably done most combinations now, and the huge bonus is the vast stock of Genuine Series Differential Parts, including Brand New Genuine 4.7 CWPs, Drive flanges, Seals, tab-locks, Bearings, early 'Bakerlight Fibre' Drive shims, Head & Tail shims, Original bolts, New Planet & Drive Gear sets, having bought all Dunsfold Land Rovers extensive Differential stock when Phillip retired.

GENUINE Series parts are often a million miles different in quality vs the modern 'pattern parts'. There are in our opinion no decent aftermarket 4.7 Crown Wheels & Pinions, we have tried them all, and they all are horrible. ! We have a huge stock of GENUINE 4.7s and 4.88s all in the original boxes, superb quality.

With the aid of our specialist knowledge experience and equipment, like the Large Ultrasonic cleaner & our Large porcelain polishing machine, we can make things come back from the brink of the dreaded skip, both saving money but equally keeping that all important originality.

There are 2 Videos to the left.

The 1st Video is a 'Top of the tree' rebuild. We took a dire example and them did absolutely everything we could to bring it back to look as good as it now does - some may even say better than new. We repainted the Casing & Centre in correct colours inside & out, reused all the original bolts & parts, repolishing the CWP and rebuilding with quality bearings. New Thrust washers, Genuine Seal, Genuine lock tabs and anything else we felt could be best for the Differential. It was an exercise we did to show what can be achieved.

The 2nd Video was a 'Nightmare Rebuild'. This was absolutely seized solid. Customer asked us to see if we could save it, oh, and if so to do a full 'Patina' Rebuild. It was truly horrendous. On collection he could not believe his eyes, and the cost was kept down as we reused as much as we could. A few parts that were really damaged beyond reuse - such as some of the bolts we replaced with the correct ones, even down to the correct maker, Re Lock wired to finish it off.

We can to build your differential back to the way you want it. When possible we like to have the customer here so we can strip them with you and discuss as we go the options and best routes to go, if not we send pictures on phones or emails and then chat through to agree a plan.

An Amazing prototype KAM 10 Spline 4 Pin + Brand New Genuine LR 4.7 CWP. Ref RD03N47030

If nothing else .....we do have some seriously rare weird and wonderful differentials !
THIS is an early KAM Differentials 4 Pin unit - in 10 spline flavour. I worked at KAM in 2009, and this waaaaaay predates that !

I am pretty sure having asked Kevin when it came in with a mass of other KAM early parts that this was a 'Pre 'Production' Center, as such
(and look at the picture of the gears) - its possibly never done any real work - other then maybe testing - they are like new !.

It's been built - or is that massively 'Way Over Built' and is seriously OTT strength wise, and as a sign of a period long gone in Differential gears - it has 'Cut and Ground' gears and not the later / current / and cheaper 'Forged Gears' so many diffs have nowdays - sadly. The center has a huge number of 12.9 Grade bolts holding the 3 x pieces together, it also has internal dowels on both flanges to center tube - basically way way over the top - erm - check out the Crown wheel flange thickness !!!

We did 10 spline centers when I worked at KAM, but they were without doubt a 'Cut Down' / 'watered down' version of this, where the more final production unit(s) were modified to save time and money,
they were bloody strong anyway - we sold a huge number of 10 and 24 spline units - all serioulsy strong - but this - this is just up there on another level

The rest of the differential has been fully rebuilt into a 'Imperial' Late Series Casing (so it has the filler plug in the casing to fill the differential) and not only that but it has it been upgraded to the full 'Ultra Spec' build including our Superflange. We have also Built this up with one of our New (old stock) Genuine Land Rover 4.7:1 Series Ratio CWPs, as being a strong centre we wanted it to be a really fabulous finished Differential to do this rare and beautiful OTT center justice.

These Genuine Series 4.7 CWPs are amazing quality, just check out the perfect 'Blue Check' !
All in all we have decided to make this unit being so unusual to make it as good as we possibly could.
A real find and frankly a rather unique diff, it beats the dreadful rusty junk dreamers laughingly shove on ebay for silly £s !! or weak 10 spline 2 Pins - this is a rare and serious differential make no mistake. ............
If you are looking for a REALLY good condition seriously strong 10 spline 4 pin in 4.7 Gearing - you've just found it.
If you want it grab it - I truly doubt we will ever see another one of these - or anything quite like it !!!!!!!!!!!!!!!! .
But, just bear in mind - This is a 4.7:1 CWP / Series Gearing and a 10 - thats a TEN spline center NOT a 24 Spline center - if in any doubt ring for a chat.

Pre Loved Series 1 80 Super Long Nose 4.88 CWP 10 Spline Circa 1948 to Early 1949

About as rare as you can possibly get in the world of Land Rover Differentials, and if you know what this is - you will know it is !

As the header says it's super rare 1948 / early 1949 Series 1 80' Super Long Nose. Fully rebuilt with all new bearings but with an unbelivable amount of effort with UltraSonic Cleaning and Polishing, it also means it's pretty much all original other than the new Bearings and Seal !. ALL the bolts including even the split pins are ALL original. It's also correctly repainted inside and out, and even the Locking Tabs have been repolished and reused. It's in exceptional condition, and who knows if we will ever have another ?.

The bearings for these are unique, seriously rare and even harder to find the best quality ones vs pattern rubbish being palmed off on the unsuspecting- and as such, when you do find them - bloody expensive. Even if found in dire states these diffs are extremely valuable carrying a large premium. So not only are they expensive to buy they are even more expensive to rebuild properly, compared to any other Land Rover differential. I am not even going to consider the labour hours spent on it, so whilst the price may seem high (if so just move on lol ) it was definately not a profit maker!

More like a labour of love - and I do love it !. (it's badly affected my 'Sad' side :O) )

YES - we would consider a similar unit in P/Ex against this, but you will need to speak to us as the CWP alone on these (if needing to be replaced) are £900 + VAT !, so, these are not cheap to either buy in or rebuild !

It's now currently sitting on my office desk, where I admire it daily - sometimes even several times a day :O)

The price above is OUTRIGHT NO Exchange unit and No Surcharges etc required - but as mentioned we would consider a P/Ex Unit - Talk to us
( ...And as we say - but more so on this one - 'When this 'Has Gone' - it's most definately gone'..... and who knows if we will ever have or even see another we can buy...... )

New From New Old Parts KAM 10 Spline Ratio 4 Pin Differential with New Genuine Land Rover 4.7 Crown Wheel and Pinion

This is a pretty interesting Series Differential - We hve built this up from all new parts !.

The casing is a Aqua Blast cleaned Primed and Repainted Series Casing 'Split Nose' Type Casing (see Pic No 1) and has the required filler plug correct to this casing, complete with the bolt on Aluninium Nose cone, a Brand Spanking new Genuine LR 4.7:1 CWP, then we have fitted a Brand New / Old Stock Built KAM 4 pin 10 spline center with its hugely strong forged internal cross shaft.

There are few, if any 10 spline options to upgrade to nowdays, much of what is out there is in poor condition, so this offers a nice mix of new parts upgraded parts and yet from the outside when fitted it will look original !.

The inside is all upgraded, HD 10.9 Grade Crown Wheel Bolts + Nordlock Washers, upgraded Carrier cap bolts with 12.9 Grade Bolts and Nordlocks, all Timken Bearings and the inside is now seriously strong, but, on the nose cone we have fitted Original Series Bolts (all repolished) along with a new drive flange (upgraded seal) and new locking tabs etc to keep it looking all original when fitted !

Fabulous Blue Print (or yellow on this one) which shows the quality of these Old but Brand new Gearsets we have, Genuine LR and they show it - in both the quality of the build and the finished item

It's lovely, rare, and a bit of a one off, we doubt we will ever have another ...sadly

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.
