im almost postive it will fit but if i can get a good deal on a expy lift and i have a 98 F150 well im just about postive it will fit except for the rear in which case i'll get some blocks or add-a-leaf or re-arch my springs but i felt i would ask first ...one more question are the rear shocks the same length

 

The front will work but the rear will have to be custom built like you're thinking. Either get an add-a-leaf or replace the rear with 1 new block. Don't stack them, its not a real safe idea, unless you like the idea of your axle walking away from you if it spits a block or it curshes. Stacking dramatically increases the chance of this. As far as the shocks, they should be about the same length.

 

hey thanks for your reply i was pretty sure it would but wanted a backing ..but about the rear i know i don't even like the thought of using on block especially 3,4" or more

 

Blocks have always sucked, always will. Its just a cheap way to get lift. The best way is to get a new leaf spring pack made. This can get kinda spendy, but its worth the money.

 

i guess if i wanted to get some real flex and go custom i could use the coils from the expy kit and build a 4 link system but i bet those coils have to heavy of a spring rate to use and i would end up spending more money than it's worth especially after what flex u can get out of leaves
