There are a lot of copies of SLR. This comes with the territory of being one of the first angle kit companies in the world. However, where others look to do it cheaper, use inferior materials, shoddy welding, and raise profits over the years – we’ve never changed. This is proven with our thousands of loyal customers all over the world and continuous innovation. Ship quality or don’t ship at all.
Built in the garage. Tested at the limit.
