1 LT230 Input Gear

We can supply the earlier FRC5428 (26T), FTC5089 (26T), FTC5087 (28T) and FTC4850 (38T) input gears.

To identify which type you need you will need to look at the your transfer case serial number. The last letter of this will denote whether your vehicle is able to accept the later cross-drilled type.

A transfer box with the suffix C onwards will accept the later cross-drilled type. See below to find the serial number :

4 LT230 SHIM KIT

Our LT230 shim kit includes two ranges of shims for both the input and centre diff.

It would be very costly to include all shims in the LT230 range so we have selected 7 shims for each range which should enable you to obtain the required thickness.

The 7 shims in each range are in the following sizes:- 0.05mm, 0.1mm, 0.2 mm, 0.3mm, 0.5mm, 1.00mm, 1.5mm,

Always use as few shims as possible to reach the desired thickness.
