Warranty, delivery and returns
The plain-English version of what we promise. One page, no legalese, with the detail where it matters.
Warranty
Covers all work and parts supplied by Gearhead Diffs. The conditions are the ones you'd expect: the vehicle is serviced to schedule, the diff is filled with the correct specification Redline oil (we supply it), and there's no misuse, neglect or abuse. Fitting it yourself is fine if it's done correctly. Want us to fit it too? Book in with the team and we'll see when we can fit you in. If something goes wrong, call us first; most things are sorted in one conversation.
Delivery
Exchange diffs: free freight anywhere in New Zealand, both ways. Order by 2pm for same-day dispatch. Overnight to most South Island addresses, one to two days to the North Island, rural adds a day. We book the outbound and the return pickup for your old unit at the same time; the label is in the box.
Parts: free freight on orders over $150, otherwise a flat $12. Beam axles, housings and other oversize items: we quote freight by phone before charging you, using Move Logistics or Kiwi Express. International: DHL Express, quoted at checkout, for parts only. Exchange diffs and oils ship within New Zealand only.
Core bond
Every exchange diff price includes a refundable core bond for the crownwheel and pinion ($250 on most models). When your old diff comes back we check the gears. If they're reusable, the bond is refunded to your original payment method within 5 working days. If they're damaged, the bond stays with us; you won't get a second bill. Cores must be returned within 30 days.
Returns and change of mind
Unused, unfitted stock items in original packaging can be returned within 14 days for a refund less return freight. Oils and fluids can't be returned once the seal is broken. Anything faulty is covered by the warranty above and the Consumer Guarantees Act.
Special order items
Wavetrac LSDs and other items marked "special order" are ordered in for you after we've checked fitment against your rego. Because they're brought in specifically, special order parts may not be returnable. We'll confirm price and lead time with you before anything is ordered; nothing is charged until you say yes.
Privacy
We keep your name, contact details, vehicle and order history so we can do the job and honour the warranty. We don't sell or share it. Rego lookups are used only to identify your vehicle. If you want to see or correct what we hold about you, call or email us.
Terms
Prices on the website are in New Zealand dollars and include GST. Exchange diff prices include the refundable core bond described above. Full terms of trade are available on request and apply to all trade accounts. Nothing here limits your rights under the Consumer Guarantees Act.
