I installed a set of these springs on my '66 coupe. They are a great replacement set for the originals that I removed from the car.
The front end had sagged so low that the front fenders rubbed the tires on sharp turns, but these springs, along with new shocks, raised the front end back to the look of the original height (approx. 3- 3.5 inches higher that before the shocks and springs were installed).
Gives the car back its smoothe ride!
