WHAT IS BETTER TO DO ADD A LEAFS OR GETTING LEAF SPRINGS REARCHED?
I WANT TO IMPROVE THE REAR SUSPENSION OF MY TRUCK WHAT WOULD BE SOME HELPFUL HINTS?
ITS A 77 F100

DRVNDBUS

I HOPE THAT I HAVE PROVIDED ENOUGH INFO

 

I would buy new rearched springs because they would not be stiff and there is nothing wrong with blocks. Many trucks have lift blocks ffrom the factory as tall as 4 inchs. ie:any F-350 4X4.

 

Mark:

When you say you want to improve the rear suspension of your F-100, is it sagging and you want to raise the back end to get your truck to ride level, or does it ride level and you want to be able to haul additional weight?

I have a '68 Mustang that I bought in 1986. It's suspension was shot and I replaced the entire front suspension and replaced the rear springs with new ones. I was very satisfied with the improvements and I still drive that car today, about 15,000 miles per year. Replacinh all the old components with new cost a lot of money, but on the Mustang there is not a lot of room so I had no choice.

Two cheaper solutions for a truck would be to locate a F-250 at a wrecking yard and measure the width and lenght of its springs to make sure they would fit your F-100. Check the truck from the back to make sure it sits level.

Another, and easier, solution is to buy some helper springs from almost any auto parts house. You can get them to add 750 lb. to over 3,000 lbs. of additional hauling capacity to your truck. Some are also adjustable so you can add an inch or more to the unladen height to rear of your truck too. I added a set of the 750 lb. helper springs to my '81 F-100. They are supposed to add 750 lbs per side but they really added 750 lbs of total capacity. The nice thing is that they did not appreciably harden the ride.

Good Luck

bruce you are correct when you asked if the springs were sagging they are badly .it would be nice if i could get more of a lift without having the buckboard effect and i shall check my local parts stores for the products that you have recommended. i thought about buying new until i found out the prices and i thought that can put alot of food on the table for the kids so i appreciate your advice thanks mark//drvndbus

 

It depends on how much you want to spend or how long you want the repair to last. I re-arched the springs on my 78 F250 4x4 because of sagging problems and I did not have a lot of money at the time. About 2 years later, I noticed the sagging returning. Eventually I bit the bullet and replaced them with new ones. They have been on there for 6 years now and there is no sag. Good luck on your choice.
