I have a set of lightly used Fox 2.5 remote resi coil overs for sale. They were on my truck for approx. 20k miles.
The CO's were waxed to prevent corrosion and the lower heim joints were always lubed with dry teflon. These CO's are fully charged at 200 PSI and setup for 3" of level (taco lean corrected) lift (with AP bumper and winch). These are the extended travel version and they have Eibach 650lb coil springs.
The CO's do not squeak, rattle, or clunk.
Remote resi bracket included, however, I do not have a spanner wrench for these. One can be bought here for cheap:
