Gas Pedal Flex Solution

[JRoyPDX]

This pedal flex thing is real.

 

For the record this is a 2017 with almost 300 miles on it.

 

I shimmed between the plastic and the firewall with a piece of 3/16 steel about 1.25" wide and 3" long. It does not move at all now.

 

Here are YouTube links before and after

 

 

 

 

 

I've already noticed a more steady throttle. No lag due to it flexing and no harsh gear hunting from it flexing back or over throttling to compensate for the flex. This is a must fix.

I have adjustable pedals and it was joke with the play/flex. I removed the whole assembly down to the plastic mount that has bolts attached to it.

I placed 2qty 1/8" thick plastic washers 1.125" in diameter over the 3qty bolts and put pedal assembly back and tightened down. I then took a plastic shim like a wood shim yet plastic and cut it down. At this point I pried up plastic mount and squeezed caulk and shim behind.

 

Took truck for "Hot Lap" and this thing now has probably 100% better throttle response! The best and first MOD evey body should be doing! Thanks OP why didn't I open this thread 1yr ago?

Excellent. So the adjustable pedals flex too?

I've been anxious to try this fix to cure what I think is crappy throttle response. I just started looking at the videos posted and mine doesn't move like that. It's fully seated against the floor/firewall area. I can pull out on the whole assembly and the pedal moves up with it. So I think there's an unfortunate group who have this bracket/assembly bent or warped, so it flexes down where it should be with any pressure.

 

Kinda bummed, because I wanted to do this fix and gain some throttle response.

Does anybody know if this is an issues on the 2500HD Duramax?

Mine did. DID. No more!

The difference is night and day. I slipped a small wood shim behind and between the left side and bottom bolts, took it for a drive without even thinking... backed out of the drive way and nearly chirped the tires with the standard amount of throttle to get going.

 

thanks to the OP!

Your welcome. I cannot believe how many people have done this mod. I thought it was just me coming from BMW's and had a very different expectation for a pedal. Turns out is a crap design that my 4yr old daughter could of done in pre-school.

I have a 2015 5.3, non adjustable pedals. I pulled the carpet back a bit and was able to jam a wood shim in there and it achieved the fix (cant see it, does not look bad in my opinion. Much easier than a bunch of bolts). No tools, no cutting, didnt take anything apart. It was not night and day in my case, BUT I for sure do feel it improved throttle response. I feel more connected to the motor. Easy, quick, cheap fix for a bit more of a real feel into the machine.

I've done it now too. Cut up a plastic scraper and stacked enough pieces to get a good fit and wrapped some electrical tape around the stack before stuffing it between the plastic mount and firewall. Makes a huge difference when I'm travelling slowly around parking garages etc and am trying to to apply light throttle.

Picked up a used 2015 about 2 weeks ago and it's not as bad as some others I've seen here, but mine is maybe 1/8". Will mess with tonight and compare.

Shoved a small piece of 1/8" plywood up under there. Definitely a different feel (a better feel) on the pedal between pressing the accelerator to the engine's reaction.

Hey, I have the adjustable pedals on my 2018 and the entire pedal seems loose and moves loosely in every which direction. I'm not sure if I have a fluke or if this is normal between all of the adjustable pedal models. I had a 2014 with non adjust and it had minimal flex but I still did this mod. Looking at my 2018 It doesn't look like as easy of a solution.

 

Any way you could post some pictures or more detailed process of what you did? Would be appreciated if you did.

I have a detailed written instructions under one post! I am not great with computers but the instructions are EXACT and will help you very much.....It never fix the "intended" floating aspect of pedal but will stop the "actual flex in materials and delayed throttle responses enormously" My post is legit and more involved than a paint stick fix.....It's a fix that your never coming back to "fix again or it might have moved etc" good luck son! Stay away from the ecoboost's man I hate ecoboost's!
