Fender Trimming Without hacking

*Chief34* · 06-03-2007, 09:49 PM

I have always needed more front fender room....

I bent my fenders jumping my truck when I shouldnt have, and at full stuff it would always hit. I didnt really want to put fiberglass on so I finally trimmed them.

I knew I would be dropping the truck down a little bit when I finally linked the suspension so I went as far as I could.

I even had to trim some of the floor out and rebuild it as well. It was all worth it though, I just need to do a litle bit of bondo work and paint them.

Here is what I started with....

If you look close enough to the body line next to the door you can already see that it is bent. Trust me it got worse since this pic........

*Chief34* · 06-03-2007, 10:31 PM

So here are the fenders after I got them off......

*Chief34* · 06-03-2007, 10:41 PM

Ok so the next part I dont exactly have pics for and I am very sorry..... BUT what I did was mark a nice smooth line coming off the curve of the fender going down toward the bottom of the fender near the doors.

I tried to make a nice smooth radius that would look good. I then used an air saw (it has a little blade like a jigsaw, but its an air tool) to trim the fenders out.

I Then cut the lip off of the piece I cut off and was able to use some of it for the lip re-building process. I also had to make some of my own to make the new lip longer. Since it goes back further it needed to be longer. (i Hope I am not losing anyone here) I used some material about a 1/16" thick and about 1.25 wide or so.

The KEY is to make the new fit as TIGHT as possible. If there is a gap it will pull and stretch the material of the fender and lip to fill the gap when you are welding. ( I found this out when I did the second fender)

So I tacked it every few inches and then went back and to fill in between tacks..... tack, tack, tack, in order to fill in while letting the material cool down between each tack. This will prevent warping.

*Chief34* · 06-03-2007, 10:45 PM

Now you can see the amount of floor board sticking out in the way.....

If you look close you can see the two holes at the bottom where the stock fender bolted..... I went so far back that I had to make a new mounting tab at the bottom and drill new holes for the fender to mount.

The next part was to cut the floor out...... I used a 1/4" air cut off wheel for this.

*Chief34* · 06-03-2007, 10:54 PM

Welding this back up was a bitch.... In that last pic you can see the insulation between the double walled pieces.... This coupled with the tar used to seal seams made it fun to weld upside down on.....

I had to be carefull due to the constant flames I was having to put out.

I used 1/16" thick metal to cut and make pieces to fill the floor... Then I welded them in.

* None of this effected the floor inside the cab at all.... *

I just had to be carefull not to do to much at once because of the heat and the carpet.

When I fist started I had the doors shut. Heh heh not a good idea at all... The toxic grey smoke that filled the cab was crazy!!!! I didnt take long either, about 10 seconds.

Anyway, here is the result, you can see where the inner fender well and how much room I gained.....

*Chief34* · 06-03-2007, 10:57 PM

I then pushed the inner fender well back and AMAZINGLY it fit perfectly. I just made a couple new screw holes on the bottom and it looked stock.

Now it just needs painted

Let me know what you guys think

*Chief34* · 06-03-2007, 10:58 PM

Here are a few more... There is a ton of room now.

*Chief34* · 06-03-2007, 11:00 PM

There is about a good 14" or so in here to the corner of the bottom of the fender there.

dont bondo a wheeler ...looks good tho

*Chief34* · 06-03-2007, 11:50 PM

I should probably add that this took me about 35 or so man hours, after work everyday for a week.

I sort have left out the steps of grinding and sanding with the air tools. Anyway, I took more time with the first fender (drivers side) and it is pretty much perfect. The pass side got a little rushed and it ended up with two small ripples near the edge of the lip.

A little paint prep and paint and it should be all good.

**section525** · 06-04-2007, 12:22 AM

Awesome work as always.

Kris G did something similar except he took an inch or two out of the entire radius of the fender. You may have to try that out once you lower it for links.

ExplorerJimbo · 06-04-2007, 05:39 AM

good job. looks real good!

do you have a sas thread by any chance?

Thanks for the compliments!! I dont curently have a SAS thread, because I didnt do the sas myself. However, I have a dana 44 and dana 60 fullwidth from a 1979 f250 that are waiting to go in. I am going to do a full write up for everyone on it. So keep an eye open, It will be a triangulated 4 link in the rear and prob a 3 link in the front. I will either use airshocks or coilovers but not definately sure wich yet. I am leaning towards airshocks at the moment. Should be fun!

It will be soon but there are a few things that have to happen first.

including but not limited to....
-Supercharger install.
-New fuel cell in the rear center.

ExplorerJimbo · 06-04-2007, 01:20 PM

sounds good... keep us posted

**FROADER** · 06-04-2007, 01:22 PM

You went to town on those things.

I trimmed mine, but not that much. I guess I'll have to cut some more when I go to 37s eh? Looks good.

*sn0border88* · 06-04-2007, 06:05 PM

when you link it, move the axle foreward. Problem solved.

*Chief34* · 06-04-2007, 10:24 PM

I can move it forward, but the whole idea was to get as much as possible because I am going to lower the truck as much as I can while still maintaining full flex. This extra room will give me some more room to lower. I will end up trimming the back also, probably just the rear not the door or anything.

Thanks for the compliments....
