F100 spring rate ? Rear 4 link/coilovers

I'm building a 4 link rear for my '53 F100 . Wondering if anyone here is running coil springs in the rear of their F100 could they let me know what spring rates they are running . Also if anyone can give me the stock suspended weight per axle for a '53-56 F100 ? Any help appreciated .

bump , anyone ?

Well I guess nobody runs coils in the rear of their mid '50s pickups then .

.

 

When I took the air ride off my 56 f100,I left the 4 link on and where the air bags were, I put coil springs from the rear of a 2004 GTO. It was cheap and easy.

 

The mid-50's chevy trucks come in at somewhere between 3100-3300 lbs. I would think that your f-100 would be close to the same. My understanding is that you ***ign half the weight to the front axle and half to the rear. Speedway's new catalog has coilover shock spring rate charts from different manufacturers. I think you'll need 350 or 400 lb. springs. I'm no expert but I'm trying to figure this out for my 57' chev. 1/2 ton also. Good luck. Sam

 

Having your coilovers tilted just one degree different will alter the ride quality, so having a guy tell you what rate he uses will only get you in the ballpark. You need to know the shock angle, as well as the weight of his exact truck, including the unsprung weight.

 

Who's coil overs?

How long are they and how much rebound at the desired ride height.

It would help to know other details like bump travel. AND shock angle as Alchemy noted above.

And also engine and trans, bed material and such to estimate weight.

 

Thanks for the responses guys , I haven't purchased shocks or springs yet . Regards engine trans etc . 368 Lincoln Y block , 4 speed manual , 9 inch ford rear . Jag IFS . Bed material - stock pickup box with standard wood floor.

I will likely run the shocks/springs at approx 15 degrees off vertical . Hope this helps so far .

Hey 4t6ford,

Did you ever figure out what coilover spring rate you needed? I am doing the same setup on my 60 and was curious to see what you went with.<o></o>

 

I used 200# coil overs in my '79 f-100 and I am going to use 200# coil overs in my '53 3100. I also like ladder bars better for the street.

 

Done a few rear 4 links for Ford trucks, used 300lb springs, worked good, would try a progressive wound coil on my own ride to compensate for differing load weights!
