I'm selling my used QA-1s. I've had these on the truck for 2.5 years and about 30k mi. They are used - note the bottom bushing that came apart on one rear and the top rubber on the fronts wasn't worth saving. They still adjust just fine and have no known functional issues. They travel smoothly through their stroke. What you see is what you get. :rock: $300 shipped to 48 states. New, they go for $640 plus shipping.
The rust on the crossbar adapters on the fronts is inevitable since they come unfinished. Mine was accelerated by salt from the salt flats so it was earned!!!! These are pending sale Monday morning.
