Description

There are many different types of LT230 transfer cases used across the Landrover range. Prices assume a serviceable exchange unit (if the exchange unit is deemed unserviceable a surcharge will apply).

The core cost is the cost to be added to the exchange cost if the transmission is purchased on an outright sale.

We are able to supply alternative ratios, sometimes with no increase in cost. A popular ratio change for the Defender is to change from the stock 1.4 to 1.2 which will raise the gearing in a Td5 90/110 or a Defender Tdi by 15%. For more info on this conversion see here

(This is a very popular gear set, especially for those with a TD5 90/110 or Tdi which revs excessively on the motorway. This gear set will enable you to raise your transfer case gearing by 15%, by replacing the gears in the exising 1.410 ratio transfer box with new 1.222 gears, as used in the Disco. This will not only reduce your revs but also reduce noise. This change will not effect Low Range and will leave your Speedo reading true.

This kit offers a simple and effective change to your vehicle and there is nothing to go wrong.

You may find it useful to use our ‘ratio calculator’

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

If you want to fit this ratio to a unit with a serial number before XXD226368E, you will have the thicker engagement teeth so you will also need FTC1084 (low range gear) and FTC382 (high/low hub).

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.

Please see below to determine whether a new input gear will be required:

Suffix C to serial number XXD308626E uses a FTC5089. A new input gear will not be required.

If the old unit is a 28D and number is after 28D308626E then it has a 28-tooth input gear e.g. FTC5087. A new input gear will be required.

If the old unit is a 36G, 41G, 42G, 68G, 69G, 70G, 80G, 81G etc this will have a 38-tooth input gear. A new input gear will be required.

If you have a 43G/57G, you will have a FTC4962. A new input gear will not be required.

Suffix A and B will be thin, FRC5428

Suffix C to F will be 5089

Suffix G will be FTC4962)

To see an explanation of our core deposit please click here

(Many of our products are sold on an exchange basis. This is an amount charged on top of the unit price which acts as a deposit and is refundable on receipt of the exchange unit (old one coming out of the vehicle), as long as the unit is the same type, complete and not stripped, and returned within 12 months.

This means it has to be like for like as it comes out of the vehicle, having not been taken apart at all, and needs to be complete with everything the remanufactured one arrives with. If it does not arrive in this condition, some or all of the surcharge may not be refunded. A standard “stripped” charge of £112.50 € will be deducted from any core return.

Core returned after a 12 month period will be subject to a surcharge as shown below.

The core deposit varies depending on the product.)

These prices assume like for like ratio’s, if you are altering your ratio additional charges may apply.

If desired we can rebuild your own unit.

If you are sending your unit to us for rebuild please see the video section above and watch “what the rebuilt LT230 comes with” before sending your unit/(s) to us. The unit/(s) you are sending in should be sent in like this. If sending both a gearbox and transfer box the units should also be separated before shipment. We reserve the right to charge up to an additional £30, plus vat if applicable, for units that are not sent in like this.

The serial number will be stamped in one of 2 possible places, either on the bottom left of the main casing or on the earlier vehicles right at the bottom of the left hand side face of the main casing obscured by the exhaust pipe in which case you will need a knife (to scrape the muck off) and a mirror. You are looking for Eg. “28D123456E”, we are interested in the first two and the last, i.e. we call this a “28E”. Please have a look in the LT230 Technical Section to find a list of Serial numbers / Ratios.

Product Options

If you would like a sleeved casing we have more information on this upgrade here.

( We would suggest an interference fit of 0.02mm and also use ‘bearing fit’ or similar.

 

If you are purchasing a rebuilt LT230 and would like to upgrade to a ‘Sleeved Casing’ please see information on this below:

The hole that supports the head of the intermediate pin in the LT230 casing is prone to wearing, and the pin elongates the hole so that it is out of round.

This can lead to a transfer case whine, and an oil leak.

Using our CNC lathe, we turn a stepped bush from EN24T steel. We mount the casing in our CNC mill, and machine an oversized hole on the correct centre and press the steel bush into the housing.

This will now have a longer life than the original housing, as the pin is now supported in the steel bush)

If you would like to sleeve your own casing we can supply the steel bush.



If you would like to upgrade your centre diff with our limited slip type please click here for details. Note this cannot be fitted as well as the HD cross pin below.

The standard LT230’s have a two piece cross pin in the centre diff, this is two shafts with a cut out in the centre so they can overlap.

We make this one piece cross pin which is much stronger. These can be specified when ordering a LT230 or sold separately.

If you are using the vehicle heavily off road you may want to upgrade to a heavy duty one piece cross pin, see here. Note this cannot be fitted as well as the ATB above.

For additional cooling, ideal in hot climates, you can add the hi cap sump to your build. For further details please see here. Please note that regrettably these do not fit the V8 vehicle as they will foul the exhaust.
