Postage Information

Small Items

Includes LSD carriers, gears and rebuild kits. Small items are sent by Couriers Please. If you are not in a service area, your order will be sent by Australia Post and will be delayed by 1-2 days. Service areas are within a few kilometers of the town center in some cases. Perth is limited to the inner metro area only.


Differentials are over 30KG and are sent by Couriers Please or TNT. Differentials are typically $70-90 to most metro areas. Differentials can be up to $120 to regional areas. Areas beyond the Couriers Please network and TNT network are not serviced, and I have no way of sending to these areas. Australia Post will not accept differentials.

You can see the Couriers Please serviced areas in this PDF found here: Couriers Please Brisbane Rates & Services Book Book. If your post code isn't listed you will have to have the item sent to a metro address instead.

You can also use the Couriers Please EzyQuote system to determine if you are in a service area. Enter 4105 Moorooka as the 'from' location.

You can check TNT coverage and prices here using TNT EasySend.

I charge a small fee for packaging materials.

Authority to Leave

If you have unattended authority to leave with Fastway, Couriers Please or Australia Post, your items are not covered by insurance if they are left unattended. You accept total responsibility for the loss of the goods if they are not there when you get home, yet the tracking shows they were delivered but not signed for.

Posting Oil Filled Products

Typically your differential is not filled with diff oil. Your diff will be marked as 'filled' if it is. Usually we do not post items that are oil filled as they will leak and contaminate other packages with oil.

The Actual Cost of Freight

Your online order may not calculate the actual cost of freight correctly. If the difference is small, Diff Lab can absorb the additional cost. If the cost is significant, you will be sent an invoice for the balance. The shopping cart does not factor in your post code when calculating freight, rather it only considers the weight of the parcel. You may cancel your order if you don't wish to pay the actual freight cost. The balance of freight owing may be sent with an invoice for a core charge if there is a fully refundable core charge owing before an exchange diff can be sent.
