Haltech buying information

Warranty & authorised dealer

Racing Solutions is an authorised Australian Haltech dealer. Everything we supply is genuine, current-revision Haltech stock — never grey or parallel import.

Haltech products come with a limited 12-month warranty covering defects in materials and workmanship from the date of purchase.

Warranty claims are handled directly by Haltech. You'll need valid proof of purchase — your original invoice or receipt. If you're not sure where to start, get in touch and we'll point you in the right direction.

If you find this exact item advertised for less by another authorised Australian Haltech dealer, contact us before you order and we'll match the price.

To qualify:

  • The competitor must be an authorised Australian Haltech dealer
  • Same part number, brand new, and currently in stock with them
  • The price must be publicly advertised and GST-inclusive
  • We compare the total delivered price, including shipping
  • Excludes clearance, run-out, sale events, member-only pricing, and auction or marketplace listings

Dispatch & delivery

If the item is in stock at our Perth warehouse or at Haltech, it ships same or next business day.

Not every product is held in stock, including at Haltech. Items that need to be built or restocked can take up to 4 weeks.

If you want a firm lead time before you order, get in touch and we'll confirm it for you.

Tuning & fitment support

Buying the ECU is the start, not the end. We can talk you through which harness, sensors and accessories your combination actually needs, and point you toward tuners who know the platform.

Over 20 years of hands-on trade experience sits behind that advice — we build and run these cars ourselves.

Not sure which ECU or harness you need?

Haltech's range spans wire-in ECUs, plug-in ECUs, terminated harnesses and plug-and-play kits. The right choice depends on your engine, throttle type (cable or drive-by-wire) and injector connectors.

Send us your engine, model year and current setup and we'll confirm the correct part number before you buy.
