5/8 shaft vs 7/8 shaft

Shocks.......whats the REAL difference between the 5/8 and 7/8 shafts....on a 2.0 shock?

Obviously a stronger shaft but also less oil in the shock body. If they're resi's or your running dual shocks it's not an issue. Dot know if it is running single. I guess it depends on how you drive your truck and where.

I know the obvious...larger stronger shaft, and IMO you dont need duals EVER on a super duty unless you are beating the heck out of it in the desert or dunes often...but thats me....duals are for the cool factor on 98% of trucks.

completely agree...i bent a 5/8 shaft on my old truck one time. I was wheeling and completely stuffed it. I think i probably would have bent any shaft.

What are you looking at for shocks on the new setup? Are there any that can handle that type of range, or are you going to have to have something made up custom?

14" travel shocks are plenty.....the shock mounts are custom included with the kit.

I agree with you entirely until you start putting monster size tires and wheels on. That much unsprung weight can use properly sized duals.
