Just put the RS5000 on my screw this weekend. they ride nice, not as firm as i expected. Perhaps since the screw is a bit heavier in the rear than many of the reviews I read here where most people thought the RS5000's were a bit too firm....

I had the IAS's on a 96 Chevy extended cab. I liked them, but I always felt i paid a bit much for what i got.. I kinda wanted to try a cheaper shock this time just to see and i feel the ride improvement with the RS5000's is just as good as the IAS.. and 1/2 the price... Of course I'm comparing Chevy/IAS to Ford/Rancho.......
