I took advantage of the buy 4 get 1 free deal on Bilsteins. These are the yellow/blue and are supposed to be heavy duty. I only put the fronts on this afternoon - rears are for tomorrow, if no rain. I had Rancho RX9000 on my truck and the fronts were fading.
First of all, I was suprised at the diameter of the bushings. They are much smaller than the washers that came with them. Also, they are not a whole lot bigger than the hole in the upper suspension arm mounting bracket. I was also surprised at the torque spec for the top nut which by the way, has a nylon insert in it (self locking nut). The instructions called for 19 ft. lbs. or 25 nm for M10 threads which is what these are. That doesn't do much for compressing the upper bushing against the washer.
The OEM specs for the nut on the OEM shocks is 40 ft. lbs. for 2 wheel drive. The Rancho shocks I had before, came with urethane bushings and both bushings were almost the same diameter as the washers. I took the truck for a drive afterward and the ride seemed ok. I guess it will take a while before I have a final judgement. Hopefully these things will hold up well.
