Review on Rancho RS999265 RS9000XL Series Shock by Juan Huerta

I bought this product in September, a pair for my avalanche 03, when I installed it I pressed it to the end to see how they return again and one of them slower another returned. I THOUGHT I SHOULD INSTALL THEM AND CHOOSE THE SETUP SO YOU CAN FEEL THE SAME. SINCE SEPTEMBER I FELT UNSTABLE DRIVING AT HIGH SPEED SO I THOUGHT THAT I SHOULD BUY REAR NOW SO THAT IT IS POSSIBLE TO HAVE THE SAME FORWARD AND REVERSE SHOCK ABSORBER BECAUSE THE CORRECT ONE (THE ONE WITH LESS PRESSURE) SHOULD BE REPLACED AND YOU CANNOT CHANGE JUST ONE, YOU HAVE TO CHANGE TWO. OF THEM SO YOU HAVE THE SAME PRESSURE IN BOTH. WHEN YOU OPEN THE BOX CLICK ON BOTH SO YOU CAN BE SURE THEY ARE GOOD. WAIT SO LONG TO UNDERSTAND THAT THEY COME DEFECTIVE. THE PRODUCT LOOKS AND WORKS TO BE DURABLE BUT CHECK BEFORE INSTALLATION.
