Bolt-In Clearance – Installing Slosh Tubz “Mild Tubz” in a Squarebody Truck
We showed you yesterday how the Goolsby Customs team fabricated a set of bitchin’ custom sheet metal inner fenders on the Goodguys 2021-22 Grand Prize Giveaway Squarebody Chevy truck. But there’s another option for solving the issue of front tire clearance on trucks like these – one that still looks good and can be installed with basic tools at home and a days’ worth of work.
Over the past two years I’ve slowly been upgrading, fixing, and adjusting my ’87 GMC Suburban in search of that “just right” static stance. Once I got the suspension to a position I liked, I ran into front wheel and tire clearance issues with the stock front inner fenders and 20-inch wheels. This is a common problem when lowering these trucks – common enough that enthusiast Mike Losh at Slosh Tubz has developed a line of custom fiberglass inner fenders (for Squarebodies and a wide range of other trucks) to solve the issue.
At the Goodguys LMC Truck Spring Lone Star Nationals event in March, I decided to take advantage of Slosh Tubz’s show special pricing and bought a set of “Mild Tubz.” These inner fenders have an OEM-style look and the company offers a version designed to work around my factory A/C system. (Wider Slosh Tubz are available for trucks with air springs and even wider wheel-and-tire combos.) I also bought the Slosh Tubz battery relocation bracket (a must have), as well as the sheet metal inner fender filler panels to clean up my engine bay a little bit.
Once everything arrived home from Texas to California (shout out to Goodguys member Deane Wilson for bringing it all home for me in the back of his ’61 Ford Wagon), I went to my dad’s shop and commandeered his two-post lift for a day and got to work. I break down the step-by-step installation process below, along with some tips I learned along the way.
