Description

We are very pleased to announce a special 1.301 ratio gear set we have made for the LT230T.

For those not familiar with these ratios, this means the input gear will turn 1.301 times for each turn of the output flanges. The low ratio stays the same at 3.321.

This ratio is ideal for TDi and TD5 Defenders which would have the 1.410 ratio fitted as standard but if they are being used as a light road car ie not regularly heavy towing they can happliy pull higher gear for more relaxed motorway driving. Until now the only option to up the gearing from the 1.410 on these vehicles was to fit the next ratio up being the 1.222. This 1.222 gearing may still be fine for a lighter 90 thats not towing much but one criticism of the 1.222 equiped vehicles is that if you are heavy it can make 1st gear a bit too tall to comfortably pull away. This 1.301 ratio gives you a good compromise if you want lower RPM but think the 1.222 will be too high. Note this can also be used in conjunction with the higher ratio 5th gear if you are changing the R380 at the same time.

This ratio can also be used if you have fitted larger tyres to your Discovery and you are finding it overgeared.

You may find it useful to use our ‘ratio calculator’ to see the reduction in engine RPM when using this ratio.

These have the thinner type engagement teeth on the high gear and so will fit the LT230’s with serial number XXD226368E and later.

To be able to fit this ratio to an LT230 with a serial number before XXD226368E, you will also need FTC1084 (low range gear) and FTC382 (high/low hub). This is due to having thicker engagement teeth on the high gear (photo shown below). If you require these additional parts, please select this in the dropdown.

Please see the photo below to help you identify your engagement teeth, note the upper teeth are the later, thinner type and the lower teeth are the earlier, thicker type.

For some transfer boxes an additional gear will be required in order to fit this kit. These gear kits are made to accept the 26 tooth input gear.

See below guide :

22D Sx C to 22D Sx G, you can reuse old input gear

28D, upto 28D308262E, you can reuse the old input gear

28D, from 28D308263E, you will need a new input gear FTC5089

36D, you will need a new gear, FTC4962

41D, 42D, 61D, 69D, 70D, (all Disco 2), you will need a new gear, FTC4962

43D, (TD5 Defender), you can reuse old input gear

80D and 81D, (all TDCi Defender), you will need a new gear, FTC4962

 

Note these cannot be fitted to the early suffix A or B LT230’s.

Please advise your serial number on ordering and we will contact you if it is required.
