I recently bought an 88 Ranger with the intent to make it a dune/desert truck. First thing first, I bought big ole tires and threw on a body lift. Because it is a budget build, I'd like to avoid purchasing aftermarket fenders and will be flaring the stock ones on my own... somehow. Before I do that though, I need to trim the existing fender wells to allow for room when turning and the future fender cuts.

On a scale of 1-10 this is a fairly easy project (2) for any first time or novice mechanic.

First let's start with the issue at hand, here we can see the fender well after removing the stock fender. The large tires are going to bump in front and back and the extra lip coming over the top won't be necessary after the fender cut.

To get going, you only need several items. Masking tape, a Dremel or whiz wheel, face protection, a deburring tool and a marker.

Step 1: Remove your fender well and tape it. I found it easiest to start right where the front would attach to the frame, and back where the rear lip hangs.

Tape makes organizing the cut pretty easy, and setting your line even easier than trying to freehand with a marker.

Step 2:Fire up your dremel and let it do the cutting, don't try and drag it through to speed up the cut.

A good cut just follows the tape and shouldn't take to long.

With the cut made, its time to make it pretty.

Step 3Grab your deburr tool and start removing the gunked up plastic/nylon and smooth out the edges. be sure to get both sides and make a couple passes.


Step 4:Once you are satisfied, go ahead and throw it back on the truck, admire your work and mark that off of your long and ever growing list of things to do.
