front suspension changes 67-72 to 74-87
 

Can anyone tell me if the 74-87 C10 has an improved front suspension & brakes over the 67-72?
What are the physical differences?
What are the handling differences?
Thanks for your help.

Physical differences?
Rubber bushings in a shell vs rubber lined steel sleeve offered more isolation for a smoother ride & less vibration being transmitted to passangers.
Bump stops are slightly different because of the slightly different spindles for drum vs disc applications.

Handling?
While the post-72 bushings offer a smoother ride quality, they also will flex more meaning slop/give vs precise alignment when pushed in corners.

Thanks for the info.
Does anyone know if it is possible to swap 73+ control arms, spindles, & disk brakes on a pre 72 C10?
Thanks

Yep. All will swap....

Are the front tracks different or the same?
Can someone tell me what the front track is for each range of years?
Thanks

I have sold 50 73up disc brake setups for the 67-72 trucks. The best and easiest IMO is to unbolt the engine crossmember (with all of the suspension/brakes) off the 73 frame and bolt it onto your 67-72 frame. You will have to drill a couple of holes to get all 7 on each side fastened. If you don't care about the upgraded bushings, use a 71-72 disc setup on your 67-70.

Here's some great info for you- "Drum to Disc" conversions 60-70

Re: front suspension changes 67-72 to 74-87
 

Will the front track remain the same when the cross member is replaced?
Thanks

6x-70 drum front ends to 71-87 disc get wider. 71-72 disc to 73-87 disc front ends there's no change. The disc spindles & hardware causes an increase vs the drum set-up.
