Help: New suspension is almost un-driveable

[Jcwilson6]

I bought a set from Alcan after having all my teeth rattle out with a tough county lift. The 2 in all spring lift ride really nicely. I still have too much bounce but I looking at some better shocks to fix that.

Try them at 50 psi.

50 is still going to be really bouncy. I run mine at 30. I've gone as low as 25 on the road without any abnormal wear.

How stiff did these trucks ride from the factory? My truck also rattles my fillings out, but it has factory springs with some lift blocks and aftermarket shocks. Maybe I need to do some investigating myself.

Wondering if you ever solved this one. Finally catching back up on some forum reading (been off here for a while). The tires have too much air in them; 35psi on a 12" wide tire for a truck only weighing 4000# is a lot. A 20" wheel does not help, you lost a lot of sidewall versus what was most likely a 15" wheel from the factory (although I acknowledge that your sidewall height did not change much).

I will echo what others said about springs; I have Alcans on my wheeling rig and they ride superbly. They have many thin leaves instead of just a few thick ones, a military wrap on the front eye and friction pads in between all the leaves. Years ago I even sent them back to Alcan for a refresh (disassembly, blasting, painting, all new pads and keepers) and they still ride great. Absolutely worth the investment.
