In my pics, I'm sitting as low as I can for right now. (pics with atv in front to push) It won't take much to changeif I decide to go lower.

I did change the bolt pattern to 5x4.5 to match the MII front. I had a machine shop do that.

I have been doing some research on what it would take to change the lug pattern from 5 on 4.25 to 5 on 4.5 to match the Mustang II front end. Apparently the 99 Cobra rear end has an axle that you could swap with the Tbird and it has the 5 on 4.5 pattern. That car has larger brakes that require other modifications to utilize the Mustang rotors. It seems like it would be easier and cheaper to have the Tbird axles re-drilled. That being the case, is there a brake rotor that is available that is configured the same as the Tbird but with the 5 on 4.5 lug pattern? If not, every time that you replace the rotors you would need to make a trip down to the machine shop. What are other people doing?

very nice pictorial Dave. I think your kit will do for the hobby IRS what Mii did for the IFS. The costs are very reasonable. Lower total cost than a 4 bar kit perhaps. Jon

Dave, I like it! Looks like a reasonable effort required for the installation, much easier that the Jag installation. I expect that you will develop some customers. It is too late for my 49 but the next truck would be a candidate. Thanks for posting the pix.

Nice article Dave! The truck ends up with a really nice ride height.

Bought One Today

Got a low miles unit out of a '93 Supercoupe today for $175 complete. Should work well with the Fatman front end we are planning on our '57 big window.

Thanks for the pics and step by step. Really helped to make the decision. How much ride height leeway is there with your kit? Is there a good way to estimate the final ride height before doing the install?

Thanks,
SPark

The only way to set the exact ride height you want is to tack weld things in place and put the bed on and any additional weight you could think of...

The install instrux and photos posted show what I believe to be the "right" height for the rear. The reason I chose Mike Chesser to assist with the install and pictures is the vast amount of experience he has with these trucks. He has installed a wide variety of front and rear suspensions ranging from Camaro, Chevelle, Corvette, Mustang II, Custom 4 Link, etc...

We took measurements from a variety of his trucks and his customer's trucks to come up with the optimal ride height... The measurements posted are all associated with the eventual ride height shown.

Having said all that, there is about 2 inches of height adjustment that can be done once things are in place.

I hope this answers your questions... feel free to post any additional questions here or email me directly.

How do you achieve the 2" of ride height adjustment?

By 2" of ride height adjustment, I meant that after the suspension is in place, set the lower control arm so that it is horizontal... Using airsprings will allow you to set the ride height at +1" or -1" ( meaning the lower control arm is pitched slightly up or pitched slightly down). This setting of +/-1" does not adversely affect the suspension geometry throughout it's full up / down travel range.

I hope this explains things... I should have clarified that in the recent post - thanks SCD for posing the question.

Is truck that you did the Tbird IRS install article on drivable? I was wondering what the resulting ride and handling is like. Has anyone else put one of these on the road?
Thanks

Dave-

Very good documentation for the installation of your kit. It will really help those wanting an IRS. Hope you sell some at the SuperNats.

thanks for the compliments... I won't be making it to the SuperNats.


... and no, the truck is undergoing a significant restoration / rebuild so it is not driveable yet.

As far as the ride quaility, since the suspension is out of a Tbird / Lincoln, the ride is more like a car than a truck.
