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

1967–1972 Chevy C10 Extreme Tubz | Wide Infusion Fiberglass Inner Fenders

Meet the next evolution in C10 inner fenders. The all-new 1967–1972 Chevy C10 Extreme Tubz take the proven styling of our Classic Tubz and push it further — filling in the inside surface to mimic the look of an original inner fender while delivering the clearance and fitment that modern custom builds demand.

Classic Looks. Modern Performance.

Designed off the timeless styling of our Classic Tubz, the Extreme Tubz feature a filled-in interior surface that gives them a far cleaner, more OEM-inspired appearance than traditional tubbed inner fenders. The result is a product that looks like it belongs — and performs like it was built for exactly your application.

Widened in Every Direction

These Tubz have been expanded in every direction to deliver maximum turning radius for the most demanding lowered builds:

• ✅ More turning clearance for slammed static dropped trucks running wide front wheels
• ✅ Full air bag compatibility for trucks that lay it out
• ✅ Wider all around — because your build shouldn't have to compromise

Built Around a Serious Chassis

The Extreme Tubz were trimmed and fitted to a Roadstershop Revo chassis. Keep the following in mind for your specific build:

• ⚠️ Other chassis designs – Additional trimming around the control arm area may be needed
• ⚠️ Will not clear factory steering without modifications – These Tubz are designed specifically for rack and pinion steering
• ⚠️ Cowl mounted hood hinges required – Factory hood hinge location is not compatible with this application

A New Standard in Fiberglass Construction

The Extreme Tubz are built using an all-new infusion molding process that takes fiberglass quality to a level you haven't seen before. The result is an underside that is approximately 80% smoother than previous models — smooth enough to run your hand across without getting fiberglass splinters. Cleaner. Stronger. Better.

As always, these Tubz need very little prep work before paint — because your time is better spent building than sanding.
