So, the rear springs on my '99 F250 are pretty sacked-out, and need to be replaced. I found a deal on a set of rear springs from a '11 F250, but don't have access to them yet to take any measurements. Anybody have experience with a similar swap to know if they'd fit or not?

Thanks!

Anybody have a newer truck they can take some spring measurements from to help me out?

 

Well, just found out it can be done, and has good benefits (apparently the ride is WAY better...) but it takes some work. the '08+ springs are longer by roughly 7" (the front half of the spring is longer) so you have to move the fixed hanger for the spring. This can be done by removing the factory fixed hanger, and either drilling and bolting it on, or welding it on further forward.

This bracket from Precision Metal Fab is another option, and allows you to complete the swap bolt-on style.

I'm gonna pick up the springs, and then decide the route I'll take to make them fit.
