quick weight question - Pirate4x4.Com : 4x4 and Off-Road Forum

trying to decide on spring rates for my coilovers but I cant find what the front end of my truck weighs anywhere and dont have a scale to go to.

Anybody happen to know what the front end of their half ton truck weighs? mine is a 1989 f-150 with a 302. if anybody has any close guesses that would be great.

The front of my 86 f150 with a I6 motor weighed in at 2,940lbs. Front corner sprung weight was 1,245lbs

do you know the spring rate of the coils that are on there now????

should help you decide on how much your truck weighs, and what rate you need....

I'm interested in what the stock springs are too. Im guessing around 200? I think my pro comp 4in lift coils were 250

prosport33 · 05-02-2012, 06:13 PM

just for reference.

the ultimate adventure f250 ranch truck that ORD built uses 300 ppi overall rate, for the coilovers.

im also using the same on my obs f350.

id say about 200ppi on your f150 would be pretty good.

holy fucking huge pictures batman

how do you resize them?

weswes01 · 05-02-2012, 06:32 PM

Iv always loved that truck. Is it diesel?

prosport33 · 05-02-2012, 07:17 PM

yep, 7.3

apparently it has the dynatrac pro80 up front and the stock sterling rear

and if i read everything correctly, it weighed in at 10k lbs. goin down the trail

ive only found like 1 youtube video where you can see it for like 5 seconds.

im still looking for the 2009 UA dvd. hopefully there is more footage of it on there.

well i just kinda guessed that the corner was around 1100 lbs. and i ended up with about a 140 ppi rating. And i got 200s over 400s. Hopefully it doesnt turn out too soft

prosport33 · 05-02-2012, 08:09 PM

its hard to say, it depends on how you want it to ride..

you can get away with a softer spring rate if you have firmer valving, and mount the CO's further out towards the inner C's or even on top of them.

did you get 16'' or 14''

im guessing you didnt use the spring rate calculator to calculate the spring rate thats currently on your truck??

ya they are going to be mounted as far out as i can get them on the axle. And i want it to be pretty soft so I think i will be ok. I might go a little higher rate on the upper or lower.

And i ended up getting 14s
