Built to order — not a shelf part
Current build & coat time: 4–14 days
Every Felder Kustom Fabrication part is fabricated after your order is placed, so lead times run longer than off-the-shelf parts. Lead time varies with our current build queue — contact us before ordering if you need an exact date.
