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 in the description). If you require these additional parts, please select this in the dropdown.
Please select from the dropdown above whether you have the later, thinner type engagement teeth or the earlier, thicker type engagement teeth.
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.
Sometimes a new input gear is required when fitting a gear set. If going to a 1.003, 1.4 or 1.6 ratio, a 26-tooth input gear will be needed. This could be FRC5428, FTC5089 or FTC4962.
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.

14) before you fit the outer selector hub and new gear pls check the selector collar drops on the gear, sometimes the sharp edges will stp it dropping over the dog teeth like this :
