I have a 2011 Ford F250 SRW, SC, 4X4, 6.2 with FX4, camper and snow plow prep packages. It has 48,000 miles on it. It rides well except when driving over choppy pavement and then it seems to dance. I'm just wondering how much these heavier springs that is on it contributes to the ride. I bought it recently and thought that it had a second pair of shocks on it but am second guessing that assumption and am going to buy a new pair for the front and the back.
For those of you who have the 4X4, 6.2, FX4 camper and snow plow packages what are your ride experiences?
My springs are DD on the front that have a 5,600# rating and LL on the rear that have a 6,100# rating. If you would please post your spring rates for your F250/F350 SRW trucks. This information can be found on your driver's side door tag. If the shocks don't work to my satisfaction I'll change my springs to the lightest ones for my model in order to achieve a better ride. Thanks
Empty or loaded?
What air pressure are you using?
The stock tire size and rating takes up to 80 PSI, running 80 PSI empty will shake the fillings out of your teeth!
You can safely drop your tire pressure from 80 PSI when empty, that will go a long ways to making the ride comfortable..
65 PSI is typically the low pressure limit for the TPMS on the F250s so I typically run 70 PSI in the front and 68 PSI in the rear when empty..
I would try that before making drastic changes to springs or even shocks.
It does it both ways but is actually worse when unloaded. I tried lowering the pressure in the tires but if that helped it wasn't much. All of the problem seems to be coming from the front.
Does anybody know what the lightest axle rating for an F250 of this year?
Axles ARE the same other than the fact you have the PLOW PACKAGE which will have a slightly higher spring rating.
I have 2wd which will not help you for spring ratings..
What you want would be the PART NUMBERS for the non plow package front springs.
Just realize however, IF you are planning to use a plow, changing the springs on the front will cause problems when the plow is on.
Personally, you could just go to a spring shop and have them custom build and install a set of springs with a slightly less rating.
You didn't say how much you lowered the pressure, but if it was only a few pounds try 65 in the front and 64 in the rear when empty.
Typically I find running the rear a couple of pounds lower than the front makes for a pretty decent ride when empty.. Too much in the rear and it gets bumpy when empty..
The TPMS on mine triggers around 62-63 so those numbers should be OK.
When loaded, you can experiment with pressures to find the butter zone provided you are not loaded to the max capacity..
I will typically run my front tires a couple of pounds lower than the rear when loaded. Typically run 80 PSI in the rear and 78 in the front while towing.
