2006 Defender 110 Td5 USW Zermatt Silver

Fitting disco gears to Defender transfer box is brilliant, especially if you have a remap. I loved it in my previous Td5, and am now considering what to do with my new Td5, as it has a standard transfer box, and I won’t let ashcrofts touch anything of mine. So I either need to fit my own gearing, or find an alternative. I don’t ever recall it being too highly geared even towing a digger, but when doing manoeuvres I would use low ratio.

Ashcroft have recently started doing custom transfer box ratios

I have slightly larger tyres (285 75 r16) and a v8 5th gear ratio on my TD5 and am seriously considering a 1.3 box to give it longer legs on the motorway without inhibiting towing capacity too much 2005 Td5 110 Hardtop

So had a quick look underneath today and found that the transfer box fitted is a 1.667 ratio. Is that normal for a 2004 hardtop to have that from standard? I was under the impression that it should be a 1.4.

Mine is fitted with 235/85/16 guessing they are standard and it is a county pack.

many TD5 LT230's were 1.410 type 43D's but had the 1.667 sticker put on in error,

Is there any other way to tell from serial number what is fitted?

Yes, if it starts 43D (which is most likely) it’s a 1.410 Dave

Thanks for everyone’s help and options with Thais much appreciated. I really wanted to go down the line of a roamerdrive but I couldn’t justify the price and also found that the transfer box that was fitted was whining internally. I opted for a discovery 1.2 and I have to say alongside the Alive tuning remap I’m running works and runs perfectly, no troubles with hill starts or anything. Seems to help with fuel consumption also. Once i brim the tank I will give some feed back on mpg for anyone else looking to change.

Thanks again folks.

Jack
