so here is the problem, i want to crank my torsion keys to make the front of my truck "level" and i want to put lifting blocks in the rear.. its an 03 fx4 4x4 and it already has lifting blocks under the leaf springs in the back i was wondering if i can stack the new blocks on top? or replace the stock blocks? any suggestions????
thanks!

 

What I would do if I were you... crank the front torsion bars until the front is level with the back. You shouldnt need to add any blocks in the back. If you add blocks you will defeat the purpose of leveling your truck.

Plus you dont want to stack blocks.

 

ok thanks alot!!!!

 

is it possible to buy 3" torsion keys for the front and to crank the torsion keys?

 

I'm pretty sure that the torsion keys take the place of cranking your torsion bars. In other words I dont think you can do both, but Im not certain.

 

thank you!

 

yea you can i bought three inch keys in mine and cranked them plus a shackle rear.
