Made In-House by Washburn's Metal

This part is designed and fabricated in-house at our Orange, California shop rather than sourced from an overseas catalog supplier — we control the material, the tolerances, and the finish start to finish. If you run into a fitment question specific to your build (shortened chassis, buggy conversion, non-stock transaxle, etc.), contact us before installing and we can walk through it with you.

The Washburn's Metal Difference

Washburn's Metal is a family-run air-cooled VW & Porsche specialist shop — every part we sell is inspected before it ships, and our team is on hand by phone or email if you have a fitment question before or after you order. We stand behind what we sell: if a part doesn't fit as described, reach out and we'll make it right.
