I'm not sure I've seen any after-market kits.
But even at Triumph prices this is a fairly cost-effective mod using Thrux parts.
The least expensive option is to modify the original (unadjustable) caps to take an adjusting screw.
Then to make the additional "disc washers"
This being fairly straight forward if you have access to the required machine tools, which I do, and of which Im working on now.
Actually I'm evaluating a group of products from this one particilar manufacturer, so until I'm done testing everything, I'm holding-off ordering just one part.
I can tell you that the adjustable caps I've been playing with have more range of adjustment than the OE Thruxton caps and (depending on cap version), they allow you to extend the forks out anouther 1/2" or so. This would be of particular interest to Scrambler owners looking for more ground clearance. The down side to the taller caps is clearance issues with low-slung handlebars like drag bars and M-Bars.
These are the types of issues I have to work-out -before- bringing a new product to market. Hope you understand.
