spring to life
If a HD 150 shares the same spring as a 250 (3" wide) and a HD 250 fits a 350. then will a 350 springs fit a 150 with a 9" rear? My 150 has a broken leaf and i want to swap up but i want to avoid excessive saging if a pull trailers.

I would think that with that many leaves it'd ride like a mexican jumping bean. I know that in my F-250HD, the ride on a bumpy road leaves a lot to be desired and if I had an F-150, I wouldn't want the ride to be that hard.

the biggest problem with using an f150 for hauling heavy trailers is not springs but brakes they aren't big enough. as for air bags just google air bag suspension there are sites that carry bags for older trucks

Also another issue with carry a heavy load is that the bearings in the rear end are not able to withstand the extra weight. I know that on my 82 F100 we broke 4 leafs on each side when we carried too much weight. Luckly we only did that once and had to replace the springs, but the bearings didn't fail that time.

Gee, what kind of trailers are you going to try to pull with an F150? A properly loaded trailer should put 10-15% of its gross weight on the trailer tongue at the hitch (1000-1500 lbs on a 10,000 gross trailer). And with that size load you surely need trailer brakes. Gross (rear) Axle Weight Ratings for 1983 F150's range from 3123 to 3730 lbs.
