    What exactly is the difference between the 1/2 and 3/4 2wd front ends? Are the 3/4 really stiffer? I am not interested in brakes, just trying to figure out ride quality differences :D

    they are same theyll ride same

    no difference

    they are all IFS with coils, same size ones and all,
    even the c30 ride the same up front, but rear be worse when unloaded due to more springs is all but hell most all the 70s 1/2 tons got 8 leaves, about same as the c30s.


    so..

    ride quality is all in springs and shocks

    2wd front ends

    The 3/4 front has solid control arm bushings while the 1/2 has rubber. the 3/4 has larger balljoints (same sizes as the 1 tons) as well.

    The studs coming out of the frame to secure the upper control arms are smaller on a 1/2 but will hold the 3/4 allright. I made bushings to go around the studs to take up the slack and used the bolt on 1ton frame supports cause for awhile there, the studs would lossen up enough for all the alignment shims to fall out. Running 33/12.50's probably doesn't help much.

    Obviously the springs are stiffer. Its all a bolt on affair and springs aren't hard to swap.

    I think the halfs ride a little better (owned both) but the big brakes are a huge bonus IMO.

    yes but ball joint and bolt size wil have no effect on ride quality

    are true points however

    arms and crossmemer and all that are same however

    springs are just different due to differnent load capacities,

    here is some info :

    1973:
    c-10:
    axle capacity; front
    3100lb
    springs; at gronud;

    :thinking: very good data thanks guys! :waytogo: my sig shows I own a couple diff trucks :D So I know what different ones ride like. My shorty rides rough but smooth... short wheelbase but 1/2 ton... and my crewcab rides smooth but rough... long wheelbase but ton dually :D and the 3/4 burb I just drove home rides nicer than I thought a 3/4 would. not as harshly stiff on bumps as the ton and not as short as the shorty :D And for now there is definately no need or sense in throwing out the 3/4 parts to put 1/2 on it.
