Gas Shocks vs. regular shocks
 

whats the big difference? im looking to do my lift soon and im trying to decide if I should get gas shocks or just do standard shocks. What are the advantages and disadvantages of each? and what would you guys recommend getting?

Have a read through THIS PAGE. It gets into the specifics of gas charged shocks and what they offer.

it def. sounds like its worth the upgrade. but is there anything special i gotta do to them?

Nope. So long as they are made for your application, they should bolt right in.
