I found the parts I needed on the Interspares website. Roxanne was so helpful — went the extra mile to get them at the best possible price, shipped them halfway across the country, and kept me updated every step. I had the parts fitted before other dealers had even sent a quote. Prices unbeatable. 10/10!

Ordered a gearbox mounting online. Even with a general strike on, I received it 2 days after paying. Good pricing and fast supply — I'll definitely recommend them!

Gearbox, diff, suspension spares & more.

We have a strong team of highly qualified staff, with vast technical knowledge and experience to help you find the right part(s).

Gearbox & Auto Transmission

  • Gears & synchros
  • Bearings & selectors
  • Manual & automatic
  • Light vehicle & truck

Differential

Diff components for light-duty and truck applications — the parts that fail, on the shelf and ready to go.

  • Crown wheel & pinion
  • Spiders & side gears
  • Bearings & mountings
  • Light duty & truck diff

Suspension

Shocks, struts and the press-fit components that go with them — the running gear that keeps vehicles on the road.

  • Shocks & struts (Monroe)
  • Control arms
  • Mountings & bushes
  • CV boots & drive shafts

The Interspares difference

Replace the part — not the whole gearbox.

We're specialists, not a general spares counter. Need second and fifth gear for a Hilux D4D? We supply the individual internals — a fraction of the cost of a complete unit. That focus, across gearbox, diff and suspension, is why fitment centres and gearbox shops come to us first.

  • Specific internal parts, identified fast
  • Far cheaper than replacing complete units
  • Specialist knowledge on the counter
How it works

Getting your part is simple.

No account needed to get a price. Send the part, we quote, you collect or we deliver.

  1. Tell us what you need

    Tell us the vehicle (e.g. Hilux D4D) and what you need — a specific gear, a diff spider, a strut. Not sure of the exact part? Tell us the symptom and we'll help identify it.

  2. We check stock & quote

    We confirm availability across our network and send you a price — usually for the individual internal part, not a whole unit.

  3. Collect or get it delivered

    Collect at your nearest branch, or we deliver countrywide from our main centres. Fitment is via your mechanic.

Delivery countrywide from our main centres.

Good to know

Questions, answered.

Both. Most of our customers are fitment centres, mechanics and gearbox specialists, but individual owners are welcome. Note that gearbox and press-fit suspension work usually needs a qualified mechanic.

Both — but our speciality is the individual internals (gears, synchros, bearings, diff components) so you can repair rather than replace, at a fraction of the cost.

Light and heavy vehicles — passenger, LCV, taxi and truck applications — across gearbox, differential and suspension.

Yes. We deliver countrywide from our main centres, and you can collect at any of our 6 main branches.

Our stock holding is large and our supply chain reacts fast, so there's a high chance we have it. Send your part details and we'll confirm availability and price.

Warranty applies to defective product only and does not cover consequential damage.
