Typically just look for them asking for your "Z height"...meaning the new, lifted static height
Meaning they will make up a set to your non-standard Z Height
I take pictures of my receipts for warranty...as most these days are printed on
thermal paper...that will fade completely in a year or so. Filed in
my warranty receipt folder....to print out if/when needed
Amazon Prime as been GREAT on returns, but have not had anything needing return/replacement
of a 'life time' product yet...
I no longer buy Rancho's anymore...they all have leaked sooner than the other
premium shocks purchased
Love/hate with Edelbrock IAS's. They leaked too
Shocks are very personal and of opinion...find someone who drives and owns
similar truck to yours and consider their advice/recommendation.
