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 :

  • Top of the Tree - Everything we can possibly do to them. Keep as 100% original as possible - Insides Outsides painted - Look like new.
  • Not to the level above. A more 'sympathetic' restoration to both differential & owners wallet ! - Still as original Looking as possible.
  • An acceptance to maybe having new upgraded bolts INSIDE but no locking wires / tabs etc, BUT Essential to look 'Original' from the outside
  • Patina Rebuild. Where we are told exactly what we can and can NOT do, things like mentioning 'Paint' is almost a swear word !!
  • 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 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.

    Please note this unit is ALSO listed in the 'All things Series' section .....we only have the one of these right now 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)

    Please note this unit is ALSO listed in the 'All things Series' section .....we only have the one of these right now !!!!

    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 !!

    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.
