He's my story, I ran stock '37 springs for about 7 years and was never happy with the ride. My truck, a 1937 has a 250 inch engine and automatic transmission. The engine is quit a bit lighter in weight then the 216 so the leaf springs were very stiff and the ride suffered. I started removing leafs, I went from 7 down to 4 in the front, 9 down to 5 in the rear. This worked quit well for a number of years, ride was much softer. I started to worry about 75 year old springs and purchased new front springs from Chev of the 40's. They were factory replacements, so again the ride was terrible. I removed leaves again, 7 down to 4 and added Teflon type slider material between each leaf. I was pretty happy with the whole setup. Fast forward 7 years, wife and I went on a long trip, ( for us anyway ) 250 miles. By the time we were home, we were tired and beat. I was at the point of selling the truck. I started shopping for a car or truck that might ride better but quickly found prices were out of my range, so I turned to the springs again. I call Detroit Springs and talked with the owner about options. I had to do some work before he could build the new springs. I needed the weight of the truck at each corner, the weight of each axle and wheel assembly, type of shocks and a lot more. I used digital race car scales at each corner and spent about four days getting weights and measurements.
Detroit Spring built four custom made springs just for my truck with the spring weights to match the weight of the truck. The ride is 95% better, I have a full 7 leafs per corner for strength, and all new hardware for safety. It was expensive, but way cheaper then starting over on another project. In this case, you get what you pay for. I paid about $1200 for all of including shipping, quite a bit for sure, but I got just what the truck needed.
