OK, excuse my ignorance but I'm just familiar with F-body suspsension. I just changed the Springs (struts in front) and springs and shocks in the back on my old Z28. What all is involved in lowering a truck 2/4? Single cab Silverado for an example. I hear about spindles, coil springs, leaf springs, etc. etc. etc. What is necessary though? Do you have to have a spring compressor like you do on f-body's? Can an average mechanically skilled person do it with a lift? Any info would be greatly appreciated.

Thanks

 

I did a Hotchkis 2/4 drop. It consists of coil springs in the front and leaf springs in the back. You just swap them out for the lowering components. Yes, an average mechanically skilled person can do this with a jack in their driveway.

 

There are a few ways to obtain a 2-4

For the front, you can get 2" drop coils, 2" drop spindles, 2" lower control arms

For the rear, you can do 2" shackles+2" hangers = 4" or 4" leaf springs (hotchkis), or theres Belltech 3" drop leafs and you could use the 1" setting of a pair of shackles.

I'm about to swap my drop coils for drop spindles (McGaughy's), and my drop leafs+shackles for drop hangers+shackles in hopes of getting a better ride utilizing the stock coils/leafs, and shocks

do you have to notch the rear frame with the 4" drop?

 

Not typically, I do bottom out but only when I hit a speed bump at 30+MPH. Anything more than 4" will need a C-notch for sure.
