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.

Ring and chat to us - we love Series Differential refurbishments !

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 4.88:1 CWP. 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

Pre Loved Tru Trac 10 spline ATB Differential plus a Brand New GENUINE LAND ROVER 4.7 Ratio Crown Wheel and Pinion

Tru-Tracs are a high quality ATB (basically a Limited Slip Differential which works via 'Gears' Vs 'Plates ) and being high quality AND as with other 10 spline units - really expensive new. The big advantage(s) of 'Gears' over 'Plates' is they don't require adjusting like a Plated LSD does, also, Tru Tracs don't need the specialist LSD Oils which are very expensive, and need regular oil changes - far more than normal.

You fancy having a fabulous new diff in your series and with the added advantage of both increased strength AND exception traction - here you are - its a stunner !

Just keep it topped up and changed with EP90 GL4 or GL5 and thats it - it is pretty much, a fit and forget (EXCEPT oil changes lol !).

This is in exceptional condition, a genuine sleeper we bough which was found on a clear out as a long lost 'spare' from near 20 years ago, so as you can see in the pictures has done little work.

Built up with a GENUINE brand new LR 4.7 Crown wheel and Pinion, into a Series ' Split Nose' Casing. We have upgraded the INSIDE with more modern / better qulaity bolts throughout and with a full Ultra Build Spec, and on the outside we have repolished the Aluminium + steel ' Nose' but fitted original bolts and new lock tabs so it can be seen when fitted as being ' original'. However - on the build we have fitted our upgraded Super flange, which will scream out as 'Not Original', but, should you like this changed we can switch it to a period new sheild at no cost at all, just tell us.

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

Here we have a really nice low mileage (been in storage for years) Dertiot 10 spline 'Auto=Locker'.

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 locktabs but repolished original bolts new dust sheild and new drive flange and seal, but the inside we have upgraded the CWP Bolts to FTC5150 Longs 12.9 Grade for more strength being its now a detriot !, and also upgraded the Carrier cap bolts again with 12.9 Grade bolts and Nordlock washer again for additional strength

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

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.
