Suspension Question

so a friend of mine has an early 99 and he says he has F450 front springs and F350 rear springs....is that similar to "X" code springs? i was thinking about doing the same thing to my truck. or maybe just F350 front springs with F350 rears. i now have a 6 in lift on my truck, but can i just bolt the 350 or 450 leaf springs up? i know i will need a different block in the rear and a pitman arm. but what else is needed?

2000 F250 SD ex cab long bed
6spd trans
south bend 350hp-750lb/ft clutch
6 in lift with 37in Km2 BFG
4in mbrp turbo back single exhaust
TS 6 Pos Chip
DIY intake
SOON TO COME
new injectors
some sort of turbo upgrade

X-Codes are 6,000lb springs...

I'm pretty sure the 450 springs are 5,600lb springs.... but I may be wrong. I would htink they would work, as long as you can adjust your track bar. Keep in mind I am guessing.

Umm...

I found mine in a junk yard using a link Buffalo444 gave me, http://www.car-part.com/

Question about plowing snow



I paid about $160ish for both X-code sorings...if I remember right.... could be wrong tho. I still need to install them.

Codes..look at the door sticker, with X codes you should get longer shocks and a adj track bar to recenter the axle. Thats it.
