Built to order — not a shelf part

Lead time: contact us for current build & coat time

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 — reach out through our contact form before ordering for an accurate current lead time.
