Genuine MARLES Steering Boxes

MARLES, a very well known name in steering gear for many famous makes such as Aston Martin, Alfa Romeo, Triumph, Daimler, Healey, Allard, HRG and Triumph etc is alive and thriving!

We are able to supply all the parts required for these boxes, particularly but not exclusively P3688, P3689, P3690 and P3691 (these references are able to be found on the main casing casting and may vary). Brand new boxes built to your specifications can also be undertaken, perhaps to replace a different box for which parts are no longer available.

We offer international collection, professional repair and return service at competitive rates via the TNT international courier network.

TRIUMPH ROADSTERS and HRG owners: There seems to be conflicting advice and comments on various internet forums about whether there are any new parts available for the original 362 MARLES steering boxes fitted in these cars. To be absolutely clear, there are categorically no new parts, no bearings, no worms, no rollers at all for these 362 steering boxes and haven't been for a long time. It is not possible at all to satisfactorily rebuild them to a useable and safe standard. That is why we are offering our slightly larger brand new 462 steering box for these cars. If you would like us to fit the steering box for you, we offer a collection and delivery service. Please contact us for more details. Thank you.

ALVIS owners: please note: we do not repair "ALVIS" MARLES steering boxes for Red Triangle Autoservices of Kenilworth and never have done. We are a completely independent private business and have no connection whatsoever to Red Triangle. David Cornwallis would be pleased to hear directly from ALVIS owners of any vintage (car or owner!) who needs help with repairs to their steering box.
