Fiberglass Inner Fenders (SloshTubz Faux Metal Mild Pair) – 1988-98 GMC Chevy Trucks

1988–1998 Faux Metal Mild Tubz | Static Drop & Mild Air Bag Chevy Truck Inner Fenders

Built for the truck that sits the way it should. The 1988–1998 Faux Metal Mild Tubz are purpose-built for the static drop or mild air bagged Chevy truck — giving you the clearance you need without sacrificing the clean, finished look you're after.

More Room Where It Counts

These Tubz are engineered with real-world fitment in mind — approximately 3 inches taller at the peak and 2 inches wider toward the outside edge of the fender, with an additional 2–3 inches of width toward the engine side. That's the extra space your dropped truck needs, designed by a builder who's been there.

Thoughtfully Designed Around Your Factory Components

Every inch of these Tubz has been designed to work with what's already on your truck:

• ✅ Clears the factory AC dryer – No relocating your AC components
• ✅ Clears the factory wiring harness – Keep your factory wiring intact
• ✅ 88–92 models clear the master cylinder and brake lines – ABS box will need to be relocated under the master cylinder
• ⚠️ Battery box will need to be raised to clear the Tubz — a dedicated solution is currently in development
• 🔧 Side trim panels are also in development for an even cleaner finished look

What's Included:

• ✅ Faux Metal Mild Tubz (pair)
• ✅ Trim patterns for a clean install
• ✅ Hole locations marked based on real-world truck build

Note: Holes are pre-marked but not pre-drilled, as locations can vary slightly from year to year.

A Note on Fitment

These Tubz are not engineered around a specific tire size and drop combination — and here's why: with so many variables in play (spindle drop, control arm width, wheel backspacing, and tire size), a one-size-fits-all spec simply isn't realistic or honest. Instead, the Mild Tubz are built to the limiting factors found in the engine compartment — giving you maximum usable space while keeping your build clean and functional.

Whether you're running a static slam or a mild bag setup, these Tubz give your 1988–1998 Chevy truck the room it needs to sit right and look right.
