Thanks guys, I will get some new shocks and springs. Have any of you done the electic suspension delete and just gone with arnott stuff? If so, how did it ride?
Some folks on this Forum prefer the OEM active suspension, while other members prefer the conversion to a passive suspension. I've had both suspensions on my truck (modified to passive by the previous owner and converted back to active by me), and IMO, the active suspension is far superior.
Arnott makes shocks (actually rebuilds OEM shocks) to be used in an active system, and they are typically priced below OEM prices. However, Arnott recently eliminated their lifetime warranty of their active suspension components, while GMC instituted a lifetime warranty on their active suspension components.
For some of the best OEM pricing, go to GMPartsDirect.com, enter your VIN, go to the suspension section, and look for the exploded diagram of the suspension components. You should find what you are looking for along with the correct part number. And, the cost will be significantly cheaper than the local dealer.
Another frequently used OEM parts site is RockAuto.com, and you can look up these parts there, as well, and compare prices.
