Question: Sulastic spring shackles

[farmerdon]

I have been looking for a suspension mod to reduce the harsh ride of our 2001 2500 HD Silverado when empty. Has anyone used the Sulastic rubber spring shackles? And did you fell they were wourth the money? Thanks.

Can't say I have used them personally, but I have heard nothing but good things about them...

I installed some on my Dads 05 LLY, and he seems to think the harshness in the ride mostly went away. I drove it and hitting the same bumps in my truck would unsettle it, and his truck it was about 50% smoother. I feel switching out the shocks would have made a even bigger difference, as his truck still has stock shocks.
