Delivery and Shipping
UK delivery — parts we hold in stock
Ordered before 2pm on a working day, these are dispatched the same day by express courier and normally arrive within 1–2 working days.
Parts supplied from our European supplier
A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.
Collection from Arlesey
Click and collect is available on parts we physically hold. If an item has to come in from our supplier it cannot be collected, and checkout will tell you so before you pay.
International
3–5 working days once dispatched. Any customs charges or excise duties are the responsibility of the buyer.

Frequently Asked Questions
Q: How do I identify which gearbox my van has?
A: The M40 gearbox is commonly fitted to Fiat Ducato, Citroen Relay and Peugeot Boxer vans. You can confirm by checking the gearbox code stamped on the casing, or send us your VIN and we will advise.
Q: Is this an OEM or aftermarket part?
A: This is a quality aftermarket replacement manufactured by SRT, a specialist in manual gearbox components.
Q: What is the tooth count and why does it matter?
A: Z:37 means this gear has 37 teeth. The tooth count must match exactly when replacing a gear to maintain the correct gear ratio.
Q: Can I fit this gear without replacing the mating gear?
A: It is generally recommended to inspect the mating gear for wear when replacing any gear. If the mating gear shows similar wear, replacing both simultaneously will give a longer service life.
Q: Do you stock other M40 gearbox parts?
A: Yes — Eco Torque stocks a comprehensive range of M40 gearbox components including gears, synchronisers, bearings and seals.
