I was wondering if someone could tell me what difference the 5 leaf springs have over the 4 leaf springs? Is there that much noticable difference?

 

1 leaf.

Had to do it, lol.

I put 5 leaf springs in and I like it. The ride will stiffen nicely, but it won't raise your car from stock height, but if you have 40 year springs you'll notice a 1-2" difference with any new set of springs. If you really want better suspension, stiffer shocks, sway bar, and other addons will improve the ride too.

PS: Springs can be restored and reshaped, but that's for really rare older cars. a new set of heavy duty leafs is probably $100-150.

 

I agree with Carlos, unless you have a 65/66 and then 4 1/2 works best. I also would go with a mid-eye (lowers the car about 1") or a reverse-eye (lowers it about 1 1/2" which is my choice for my 66). The car may seem to sit higher at first, but usually drops about 1/2" as the springs settle in.

 

I do have a 66 Mustang, but I just plan on using it for regular driving and will not be racing it or going on road courses and such, will I still notice much of a difference between the 4 and 5 leafs?

 

You will not notice a huge difference. The 5 leaf will be a little stiffer and maybe a bit harsh over bumpy roads at speed. If you were road racing it, I would say 4.5 leaf, with a 3/4" sway bar and a good set of Koni adjustable shocks.

 

I put a 4.5 leaf on my Mach 1 with a 7/8" sway bar and it is pretty stiff. You can tell a big difference between it and the old stock springs. I would think the 5 leaf would be pretty dang rough for street use.

 

I've got 4.5 leaf mid-eyes on my 67 and I love them, but I agree, 5 leaf springs would probably be bordering on too stiff.

 

Thanks for the replies everyone, I'll stick with the 4 leaf springs when I replace them.

 

BTW, i didn't see it mentioned. The half leaf should help reduce wheel hop, by limiting axle wrap. added feature over the straight 4 leaf.
