The wait is over. The all-new 1960–1966 Chevy Truck Extreme Tubz are here — and they're built specifically for the truck that's going all the way down. Engineered for air bagged Chevy trucks, these are the inner fenders your build has been waiting for.

Built Extreme. Built for Bags.

These Tubz measure 7¼ inches taller than the top edge of the factory fender — giving your air bagged 1960–66 Chevy truck the clearance it needs to lay out without compromise. No trimming the top of your inner fender. No hacking up factory sheetmetal. Just serious, purpose-built fitment for serious builds.

Premium Fiberglass Quality

These aren't your average reproduction parts. The 1960–66 Extreme Tubz are among the finest fiberglass inner fender products on the market — smooth, clean, and requiring very little prep work before paint. They're built to look as good as they function.

Please note: These Tubz are shipped and handled multiple times before delivery. Minor imperfections such as small scratches or chips can occasionally occur in transit. Rest assured — you are still receiving one of the nicest fiberglass products available anywhere.

Fitment Details

These Tubz are trimmed and designed around a stock frame with Ridetech control arms. Here's what to keep in mind for your specific build:

• ✅ Stock frame with Ridetech control arms – Ready to fit with minimal work
• ⚠️ Stock steering box – May require additional trimming for clearance
• ⚠️ Other chassis designs – Some additional trimming around the control arm area may be needed, as all chassis designs vary slightly in that area

As with any custom application, minor fitment work may be required depending on your specific setup. That's the nature of building a one-of-a-kind truck — and these Tubz are ready to be part of yours.
