Front suspension question for Cummins swap

[C20scott]

I used the Tuff Country HD 4" lift springs on the front of mine. They barely even deflected under the fully dressed weight of the 6BT and were so rigid that when i jumped on the bumper with all my weight, i could get about 1/2" of movement(if that). I ended up taking the shortest leaf out and effectively made them the "EZ Ride" version. I am satisfied with them now.

My unvalued opinion would be to NOT go with the "HD" springs if you choose to go with Tuff Country. Having a stiff front suspension is the worst... You can always re-evaluate your ride height after the engine is sitting where you want it, not the end of the world.
