4" lift leaf springs

[80 Chevy K20 4x4]

I just got a 75 Chevy SWB 4x4 with brand new 35x12.5R15 Mastercraft Courser tires on 15x10 black MT wheels. The current lift looks like an older 2.5" suspension lift. I need more front tire clearance, so I'm looking for 4" front springs.

I used to run Tuff Country EZ ride 4" front springs back in the 90s. Are Zone Offroad 4" springs made by BDS, and do they provide a true 4" of lift, and do they ride as good as or better than the TC EZ springs?

Also, it has this aluminum t-case but I don't know which NP model it is. Does anyone have an idea which one it is?

No idea on the spring questions but that appears to be a replanted NP-208 from a 81~88 square.

A picture that’s a little further away will help verify for certain.

That t- case should have a round tag rivited on the back telling what it is.

The tag is missing on it. What is the shift pattern of the NP 208?

 

[tarussell]

Judging by what little can be seen by the pictures and the type of tail housing it has I’m confident it’s a 208.

The 208 shift pattern is 2-high all the way forward - then one notch back is 4-high - then another notch back and a slight shift to the right side is neutral - then one more notch back is 4-low.

2H
4H
