After some debate I have decided on going with the 4.5/6 lowering kit from Mcgaughy's and replacing front and rear shocks as well for my 77 GMC step side swb.
The kit comes with 2.5" drop spindles and 2" drop springs for the front and a flip kit and c-notch for the back. I am also ordering the lowered shocks for the rear and replacement shocks for the front, both also from Mcgaughy's.
I am wondering if there is anything else I should plan to replace upgrade while I am down there and have curious if I should plan on swapping bushings, bump stops or anything else while I am at it.
