From the fact that the OP only has 6 posts under his belt I'm gonna guess he's new to the board.... So WELCOME!

That said, these trucks do have some of the best suspension you cam find under an older car. There are many upgrades you can make that are affordable. The first and most important I feel is a disc brake upgrade. The 73-87 c10 front suspension is nearly identical to the suspension under our trucks, yet has upgraded bushings and ball joints, as well as disc brakes. I swapped an entire setup from an 85 under my 68. The cross member, shocks, a arms, disk brakes and calipers, and steering bars..... the whole shabang, and it nearly bolted right in. The only other necessary upgrades in my opinion will be an updated set of springs and a sway bar. Even with the stock 85 c10 springs up front, and the stock 68 coils in thw back, it still handles pretty well and I haven't lowered it.
