The idea for Stagweber International started in 2010 with the Weber twin-choke carburettor conversion. The originator, Chris Spain, a retired Professional Electrical Engineer (MIEE), wanted to continue to apply his mind as an engineering designer, and having worked on a Weber 38DGAS on a 3.0 litre Ford V6 engine based project, he decided to design and manufacture a kit to fit the Stag V8 engine. Following success of this project, and others like the header tank, fuse box and fan cowl he has coninued working to develop other enhancements, most of which are featured on this website.

Based in Walton-on-Thames, Surrey in the UK, as well as being the designer and sole supplier of these special products, Chris is also a stag owner, enthusiast and *specialist, and may, from time to time be able to offer other products and services not described here (but see 'Other' page), and of course free advice to other stag owners. Why not tell us of your problem, an email costs nothing! Help: If you are unsure about your ability to fit our kits, please call Chris to discuss it. He can talk you through an installation to put your mind at ease.

Chris was a long term member of the Stag Owners Club in the UK, but has now left the club and formed a new group of Stag Friends.  However, membership did bring about a close link to the Stag owning community, and helped us to develop great new products for the enhancement of the marque.

*Specialist:-  Note that Chris specialises only in parts for the Triumph Stag. That does not mean he claims to be a Stag expert! 


Our products are designed and tested to fit and work on a standard UK home market (right hand drive) car.  Although they may fit and work on export models, we cannot guarantee this. Please check the individual product descriptions for further information.

Quality Assurance:

We work hard to ensure that our products meet the highest standard. Where possible, the type of products we supply are tested, installed and run continuously on our own Triumph Stag.  So far we have had a very positive experience with them, and they continue to make owning our stag very enjoyable.  Our special products are manufactured locally in England, and we take great care to make sure the parts are all fit for purpose.  As a consequence we have every confidence that the products you receive will be of good quality.  We operate a policy of continuous improvement, so we regularly review our designs, and update them where necessary.

Ordering/Buying:  (see home page for our working days)

GENERAL. When planning any work on your car please buy and fit our parts well in advance to allow plenty of time to check and rectify any unforeseeable problems. Parts are usually in stock, but occasionally may be out of stock, so if time is critical, please enquire first before ordering.  When items ordered are out of stock we will do our best to notify this on the website. Please also read our disclaimer and only buy if you accept the conditions therein.

ONLINE. Please make your purchase, wherever possible, online via this website: All major card payments accepted for online payments via our Paypal based system. Just select (click on) the tab for the product of interest, select the items, options and quantity you require, and then click on 'ADD TO CART'. When you have finished, select 'CHECKOUT' and just follow the payment instruction provided.  Make sure to scroll right to the bottom of the page to click on 'REVIEW ORDER'    then scroll down on next page to 'SUBMIT ORDER'.   NEW: To pay for other items not shown or where the price is diffferent, you can send us money by clicking on the 'Paypal.me' link on the home page, but please include a message with reference to the item required.

OTHER ORDER/PAYMENT METHODS: Note: we are unable to take payments over the phone.  If you are unable to order via our website, please give a full list of all the parts and options using our 'Contact Us' form. Then we will send you an invoice for you to pay.  

*Please note: Our postal charges are calculated approximately, based on your location, and will be visible at checkout. Where the postage costs to us far outweigh the price quoted, we reserve the right to either cancel the order, or charge an additional fee to cover the excess.

Note: PayPal e-cheque payments, and paper cheques can take 5-7 days to clear, and will therefore delay dispatch of your goods. To avoid this please pay by card if possible. For more information on e-cheques refer to the PayPal website. Goods purchased via our website system should only be posted to your billing address for reasons relating to buyer and seller protection.  Any other address specified may not be protected.

SPECIAL ORDERS: To avoid any misunderstanding we advise all details of special orders (e.g.. for hoods etc) must be confirmed in writing (e.g.. email)  by the customer.   Prices quoted verbally are for guidance only, and are therefore not binding unless confirmed in writing.  

It is our responsibility to supply you with goods that meet your consumer rights. If you have any concerns that we have not met our legal obligations please contact us.

Packing and Delivery:

Because we are a small business, processing orders may take a few days longer than expected. Our store may occasionally close without notice due to holidays or other reasons. 

Orders are normally processed in the morning on our working days (as shown on our home page). Postal services we use vary from Royal Mail 1st class to Courier (typically 2 to 3 days within the UK), and usually require a signature on receipt, but please ensure that any package damage is recorded on the delivery documents when you sign. Sorry we cannot specify arrival dates.  Our couriers will make reasonable attempts to deliver and get a signature, however if the courier is unable to deliver and returns it, the purchaser will be responsible for any cost of redelivery.  For more urgent orders please contact us first to see if we can help.  We always try to keep postage and packing costs to a minimum and, if you ask us, we will gladly pass those savings on to you, for example by combining packages.  Please check packages and make sure any damage is reported immediately, and recorded with the delivery person. 

Order progress and Tracking: Our online shop does not provide any order progress information. If your order does not arrive soon after the date expected, please contact us by email for a progess report, tracking reference etc.  To calculate your expected delivery date, choose the first order processing day after your order, then add 5 working days for UK delivery, or up to 14 days for worldwide delivery.

Cancellation and Returns:

After you have received your item, in the unlikely event that you decide to change your mind about the purchase,  please contact us as soon as possible so we can explain the returns process.

If you have an item which you believe is faulty, please contact us to discuss before returning it to avoid unnecessary expense or delay.  We will try to help with diagnosing any problem you might experience with use of our products.  Deliveries to us: We cannot accept responsibility for deliveries to us outside office hours unless pre-arranged, and confirmed by email.  

All our products are designed to fit a standard Triumph Stag.  If your car has other modifications which interfere with the installation or working of our products, we obviously cannot advise on this as we do not have the opportunity to carry out the necessary test and checks.


After receipt of your item, if you are satisfied with it please email your comments to us (if you prefer your feedback not to be included in the testimonials, please state). In the unlikely event of non-delivery, or any other query or problem, please notify us as soon as possible via the CONTACT form or email.
