Rancho's Pro-Series RS9000X Coilovers

(Some assembly required)

The unit is shipped unassembled. This allows them to package the springs separately making it easy to change them for shipping.

 

Assembly is simple and quick.

First, un-box everything and account for all the parts. Always read and follow the factory instructions.

 

The threaded sleeve has a collar inside. This is the top.
Thread the collar onto the sleeve with the shoulder down.
Slide the sleeve with the shoulder up to and over the wider shoulder on the shock body.
The smaller spring (the tender) goes on first.
The black slider goes on next. Face the large end down. Then place the main spring onto the black slider.
The shoe slips over the rod and seats on the bottom of the rod. Turn the collar on the sleeve and seat the spring into the shoe. Turn a few more turns to put some tension on the assembly.
Here is the completed assembly. Once on the vehicle you can adjust the lift of the shock to adjust for level, or change in weight.
