Exchange diffs and diff parts for Tasman

Tasman is horticulture, forestry and a lot of hills. Apples, hops and kiwifruit around Motueka and the Moutere, pine on the Richmond Ranges and the Takaka Hill road standing between the rest of the district and Golden Bay. It is a long drive from Christchurch over the Lewis Pass, but a short hop on the courier: a rebuilt exchange diff dispatched from our Sydenham workshop typically reaches Richmond or Motueka in one to two working days.

Courier: 1 to 2 working days, typically Freight: free, both ways Warranty: 12 months or 20,000 km

The vehicles are what you would expect from orchard and forestry country. Hilux, Ranger, Colorado and D-Max utes towing bins and trailers down wet rows, Land Cruisers on the forestry roads and the Takaka Hill, and Navaras on the lifestyle blocks. We stock rebuilt exchange units for all of them, in open and LSD form for most.

Freight is free both ways and the return label is in the box. Golden Bay and the more remote valleys are rural delivery, so allow an extra working day each way there.

Courier from Christchurch to Tasman

1 to 2 working days, typically

Dispatched from Christchurch on the overnight network. Alpine passes and the far south can add the second day.

Indicative only. Transit depends on the courier network and the time of day the order is placed. Tracking is emailed when the unit leaves the workshop.

  • Rural delivery addresses: allow an extra working day each way.
  • Oversize or heavy items such as complete beam axles travel with Move Logistics and are quoted by phone before anything is charged.
  • Freight on exchange diffs is free in both directions. The return label for your old unit is in the box.

Vehicles we see a lot from Tasman

Orchard, hop garden and forestry utes, and the 4WDs that cross the Takaka Hill. Tasman shortlist.

All exchange diffs

Not seeing your vehicle? Around 120 units are on the shelf and not all are online yet. Send your rego and the team will check.

Fitting it near you

Richmond and Motueka both have workshops that look after the orchard and forestry fleet, and Takaka has mechanics who keep Golden Bay moving. Any of them can fit an exchange diff head. The unit arrives with fitting notes and the ratio tagged, and the team will talk a workshop through anything unfamiliar before they start.

If the vehicle lives on orchard rows, ask for the pinion seal and the breather to be checked when the swap is done. Wet clay and spray water find their way into a diff more often than people expect.

Guides worth reading before you order

Ordering from Tasman: common questions

Do I need to send my old diff first?

No. The exchange unit ships first so your vehicle is only off the road for the swap itself. The price you pay up front includes a core charge for the crownwheel and pinion, and that is what covers the workshop while your old unit is on its way back. Once the old diff is boxed and collected, the core charge is refunded if the gears are reusable.

Is the core charge different for out of town orders?

No. One price covers the diff and the core wherever you are. The core part is refundable and comes back to you when your old unit arrives in Christchurch and the gears check out. The only thing to watch is that the old diff actually goes back, because the refund cannot be processed until it does.

Can I do the swap myself?

You can, and plenty of customers do. The unit comes with fitting notes, the ratio is tagged on the housing, and the team is a phone call away if something does not look right. The warranty stays valid when the diff is fitted correctly and run on the specified Redline oil. If the job means pulling a beam axle, pressing bearings or setting up a front diff on a 4WD, a workshop is usually money well spent.

What if the diff that arrives does not fit my vehicle?

The diff is matched to your rego and ratio before dispatch, which catches almost every mix up. If something still does not line up when it arrives, do not fit it. Ring the team, the right unit is confirmed and sent, and the return freight on the wrong one is handled by the workshop.

Still not sure? Call 03 381 0320 or send your rego and the team will match the right unit.
