F100 Mustang s550 IRS Swap 

Bumpsides and 73-77 Dentsides are goated.

I did the mark 8 irs and it turned out just as clean. There is a lot of work to get them this far. Good job and keep them coming.

After painting it looks so clean! Seriously looks like a brand new factory frame on an assembly line!

I'm so stoked I ran into your guys videos. Earlier this week I was at a stand still on my next move. I was trying to figure out my potential ride height and felt the Crown Vic front I put in was too high. Of course there is no drop spindle kit and then Eaton springs was a last hope until I started reading their customer reviews, No Thanks. After seeing you put that IRS in I have no choice but to put one in myself. I'm building a 1970 F-100 uncut short bed. The motor I have is a 1997 DOHC Cobra 4.6. I will need someone to tune this Beast once its all together also. I need a gas tank. I'm in need all the way around. Looking forward to meeting you guys!

Looks great. Thanks for the inside information

Good info! Thanks for posting

badass. great video. i was leaning towards doing the 8.8 for cost savings but this just put me back on the mustang irs track.

Awesome. Thanks for posting!

Thank you for this!!!

Nice work!😎🇺🇸

Came from the F100 page to watch this. And subbed for more content. I am working on building my own F100 and looking forward to more vids lads.

Been following on IG. Just subbed here as well. Good basic explanation.

Nice job!

Great video thks

Looks great. Job well! Enjoy your channel. New sub here.

I have done this a year ago on a Ford F100 1966.in the uk. I cut the frame,boxed,and tabbed mounts to unbolt oem.on coilovers

G’day mate, may I ask what wheel and tyre sizes you are running front and rear? Brands as well. Best video this.thanks

Great video, what is the height from the ground to the top of the mustang irs where the chassis sits on the mounts.?

Looks really good. I can’t wait to hear how it rides. Have you heard of anyone installing the same IRS on a dentside ?

That’s pretty cool and I have a question how many inches of travel does that it’s have? Like free movement for bagged purposes.

Good vid on the basics, will you share tire/wheel size and backspacing?

What size tires you have on this? How much drop you think it has overall after all of this work. Thx

What Brand Coilovers did you use on the front of the CV subframe and do you have a side pic of the cab so I could see the rack of the truck? Thanks

Why didn't you go with a c-notch option in the rear vs cutting the into frame c-channel?

Hey what's up man.. do your coilovers have to be on when you figure out ride height

What are the dimentions of the wheels you used?

I plan to do this to my 67 mustang . Any pointers?

I see that you used a nice wide tire. Will I be able to use a wheel with some lip? I have already purchased Rocket Racing Wheels 20x10.5 0.1 offset 139.7 Backspace

Yeah I am about to do this but too low for me. You all go ahead and watch this . Just not my way is all

Can you include in your video your wheel specs as I am sure more people would like to know what we can expect to use. Width offset ect

What year was the s550 from

What size coils did you use in the back ?

You guy build a kit for this conversion

wheel and tire specs?

What a pain in the butt looks like. Solid build though!

I have a 72 f100 and wanna do the irs swap. Díd u have to modify ur dif.
