Low Rear Suspension
hello all. I have a 01 f250 superduty that had a 4" lift with 315 tires. Couldn't stand the ride. So I had a local off road shop swap out the lift for original suspension, with a 3rd leaf in the front to carry a boss snow plow. Problem now is that i see is the rear end sits very low. haven't taken a tape measure to another truck but it seems alot lower than most other 250's espically since i put 285's on. The mech. said to give the front 2 wks to settle because of the third leaf he put in was new and it will take time to settle in so the front will lower about 3/4 of an inch and the rear will actually come up a little and it should level it out. He also said it is because of the topper that is on it. The rear suspension is missing the overload springs and i was wonder if this is the reason why it is so low in the rear? If there is not a problem with the rear springs is ther a block so I can level the truck back out
Hope to hear from you soon

There should be a block under the rear springs, most likely 2 in.(4X4). Not all F-250's come with helper springs, so that's not odd. The only real problem is knowing what the original rear set up was in the first place.

Yup, 2 inch blocks in the rear were stock - if it's a problem, you could have 4" blocks put in there and it would level it out more.
The overload springs don't come into play until the rear suspension has been compressed 3" or so, so that's not the problem. Do you have a thick, flat leaf on the bottom of the spring pack in the back?
And yes, the fronts will settle a little bit, but my brand-new heavy-service suspension with over 20K rough miles on them (T front springs) hasn't settled more than 1/2" yet...

hey thanks for the info and to answer krewat question to a thick leaf spring. yes it seems to be a little thicker than the other four. So that would be 5 total
should i just go with a spacer block. Measured from top of tire to fender and got 9in at rear and 10 1/2in in front
Thanx cfd312

I'm assuming you don't have a spacer block, if thats the case somebody screwed up because all 4X4's come with some kind of spacer block. F-250's come with 2 in. blocks, and F-350's come with 4 in. blocks. Not that simple, some blocks are flat, and others angled depending on your wheel base (single, or 2 piece driveshaft). Good luck if your just grabbing at straws.

hey guys. yes i checked after writing this message because i called the place that changed over the suspension and he wanted to know how big the block was. it is 2 inch block so he ordered two new ones yesterday a 3in block and a 4in block. should get it on monday and will take him about a half hour to change. he is afraid to go with the four in. because he thinks it will look like a stock truck after it levels out. so he suggested going with the 3 in because he is certain the front will come down.
any other comments are most cool
thanx cfd312

I have a third leaf on my front springs and 4" blocks on the back. I am also running a 7 leaf main spring and 5 leaf overloads on the rear. I have a dump bed that is probably a little heavier than your stock bed and topper. Truck still sits higher in the back than the front. I am adding a 4th leaf to the front springs when I swap my front axle out.
I plow snow as well. The third leaf on the front springs only raised the front 1/2".
The extra leaves in the rear don't raise the truck, the rear just does not come down till you load a couple of tons.

hey like to thank everybody with there input. it is really helping out. have not felt any vibration. do you all think i should go with the 4in block or the 3. do you think the front will come down (right now rear is 9 in and front is 10 1/2 in) am afraid if i go with the 4in it will raise the rear. i want to make it as level as possible. with the plow (boss 9'2" hopefully putting on this winter) i know the front will lower. so just driving around it would be nice to have it level (for me GOT to have LEVEL). also with 315 75/16 the transmission did alot of down shifting out of overdrive, now the 285's are on it, it don't (thank god) was wonder if i went to a 295 to take up wheel well space if i would have the same problem with the down shifting?thanx cfd312
