Warranty claims with Offroad were a PITA. . . you have to buy another set of new shocks, send yours in, only to have the warranty denied because they claim Bilstein tested them and said they're fine. Happened to me with my blue & yellow shocks with only 25k on them, rt front tire was bouncing excessively thanks to one almighty pothole I found in Kennesaw Georgia. The left side wasn't much better. . . new shocks totally cured the problem.
Other places will take your word for it and replace the Bilsteins, make sure of that if you're getting the blue/yellow ones since they have a mediocre lifespan. My 2nd set of Bilsteins have a little over 20k and are about done.
