  • Front suspension height problem

    Hello all, seasons greetings! I've finally found the time to dig into a problem on my '65 Thunderbird, low mile survivor.

    The front sits way high, 29-3/8" to the top of the front wheel openings when it should be 27-21/32". The previous owner replaced the front coils from a well known Thunderbird specialty supplier. The shocks look like standard issue replacement duty shocks, the tires are standard size 215/75/15. So... I'm sitting an inch and a half too high for some reason.

    The rear springs were replaced last year with leaf springs also from the same supplier. I called them last year and they can't see how the front coils could have been made wrong or mixed with another coil as they don't make anything similar to the Thunderbird coil.

    Lastly, the car is a 390 with A/C so it isn't a case of coils for an A/C car installed on a non-A/C car.

    I'm out of ideas now - thoughts on where to look next? This seems like it shouldn't be so hard to figure out but has me a bit stumped!

    Well, you could take the insulators from the top of your front springs out and replace them with a thin rubber pad. That would lower your height without affecting the ride. The cost would only be for labor. - Dave

          Thanks for the post, I also am concerned about a higher front end. I just measured the front of my '66: to the top of the front wheel well is 27- 3/4", just slightly above your stated spec. Visually, the car stands slightly higher in the front than the back, confirmed by holding a spirit level against the rocker panel. I attribute that to 1) the engine is lighter due to aluminum heads and intake and 2) the rear leaf springs have lost some springiness over the years.

          That probably doesn't help with your problem, though.

            Well, you could do that evil deed that I'm always willing to do, if the springs on the car will allow it (The flairbirds allow it in spades). Pull the springs, cut a qtr coil, reinstall and see what you get. That's how I lowered two of our flairbirds and my 58. Suffered no ill effects on any of them. Some will complain the idea is terrible so it's up to you. I lowered our 65s about 2.5" up front and 2" in the rear to get them to sit where I wanted them.

            Visually, the flairbird will always look like the front is higher because the rear deck drops down a bit. I set mine based on how I wanted it to sit in relation to the belly pan to the ground and the wheels inside the wheel wells.

            Cheers
