I need advice, bought a (mostly) freshly completed steel ’40 Ford coupe, 350, aluminum heads, intake, tube headers, no A/C to be added later. With a Mustang II from a distributor.
They told me they combine from various sources and package their kits in house (?) I have identified the spindles, no idea of other sources.
The Coil springs bulge and rub on upper ball joint housing.
Lower a-frame is not parallel to ground.
Car sits a tad on the low side with 2″ dropped spindles (I have a set of stock spindles to install)
This seems like a strange situation to me, I am happy with the ride quality.
Is it simply I need a shorter spring with the same rate?
Is it advisable to cut these springs?
Thanks for your time,
Jim,You are certainly right in thinking the springs should not be bowed so much to allow them to be rubbing.
A slight amount a bow does sometimes happen, but it is very minor. Cutting the springs is not the answer because when a coil spring is cut it becomes stronger.
But there is a cure. Without knowing for sure what springs were in the kit used on your car, we have to establish a baseline. This would be done by installing a set of our part number M24046 Mustang II Coil Springs.
You can see why I choose this spring from our online chart: Mustang II Coil Springs
See the 1940 Fat Fendered car with a small block.
We find that the recommend springs on the chart work in the very high 90% of the time.
Now, should you be one of the ones on which the springs do not do the desired job, we at least know what spring is used and what spring needs to be used to solve your problems.
Provided the 1st set of springs have not been altered, painted, abused or played with by a 5 year old, we will exchange them at no charge. You simply pay shipping.
