Fiberglass Inner Fenders (SloshTubz Pair) – 1967-72 GMC Chevy Trucks

1967–1972 Chevy C10 Mild Tubz | Heavy Duty Fiberglass Inner Fenders

More room. Better fitment. Zero compromises. The 1967–1972 Chevy C10 Mild Tubz are built for the builder who wants a clean, functional inner fender upgrade that installs like factory and performs like custom. Designed for static dropped and mild air bagged C10s.

Built for the Smooth Firewall, Factory Hood Hinge Build

These Tubz are specifically designed to work alongside a smooth firewall and factory hood hinges. Some modification to the factory hood hinges will be required, along with trimming part of the inner fender bracing — standard work for any serious C10 build.

Dimensions That Make a Difference

Every inch of extra space was carefully considered:

• ✅ Approximately 2 inches taller for added vertical clearance
• ✅ Approximately 2 inches wider in the turning area for improved wheel clearance at full lock
• ✅ Outside edge raised approximately 4½ inches straight up around the bolt-in flange for maximum fender clearance on lowered applications

Bolt-In Installation — Just Like the Originals

No hacking. No fabricating a mounting system from scratch. These Tubz bolt in using the same mounting locations as your factory inner fenders — keeping your build clean and your install straightforward.

Premium Fiberglass Quality

Built from the same heavy duty fiberglass used across our entire Tubz lineup — smooth, clean, and needing very little prep work before paint. These are among the finest fiberglass inner fender products you'll find anywhere.

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. You are still receiving one of the nicest fiberglass products available anywhere.

Fitment Details

• ✅ Stock frame – Trimmed and ready for stock frame applications
• ⚠️ Other chassis designs – Additional trimming around the control arm area may be needed, as all chassis designs vary slightly
• ✅ Outside edge intentionally left slightly long – So you can dial in your exact preferred fitment. A scribe line on the black side shows exactly where the builder cut his for his personal install

As with any custom application, minor fitment work may be required depending on your specific setup.
