lowering screw
The truck drives great!!! I used the belltech shocks, I got the kit from summit and they actually had two different offerings in shocks. I told the guy I wanted the stock ride and he sent me the whole kit for that request.... I need to upgrade my brakes to slow this thing down now.... I really like the feel... I took it up to a 100 or so to see if I would get any vibration but she did very well. Overall I am very pleased with the kit and you guys gave me some damn good advice!!!! Thanks
Need some help from you all that have done a 4" drop in the rear.
My shop is telling me that the shims that came with my kit are too thick and will throw the driveline off if they install them, which potentially could cause damage to the rear end. Can someone please measure the thickness of their shims that came with their lowering kit for me??
Also, does anyone know how to contact Western Chassis directly?? I cannot seem to find them on the internet.
Thanks for any help!!

Never mind - finally found the number for Western Chassis (direct) and talked to one of the shop guys. He said I definitely need to install the shims and that the directions were wrong if they say that the shims usually are not necessary for Fords.
My shop is going to take care of it Saturday.
Other than this issue, I love the lowering kit. It is starting to loosen up a little where bumps are not as noticable as when it was first installed (that or I am just getting used to it). And the handling is awesome - finally I have a "Sport Truck"!!!

from DJM's tech page
On most applications, DJM recommends completing the installation and test driving before adding shims. Many vehicles will not have any vibrations so shims are not needed.
A very common question DJM tech get is "Which way does the shim go?". The answer depends on the application. Pinion shims are most commonly used for hangers and shackles on full size trucks (Chevy, Ford and Dodge). These vehicles have the leaf springs on top of the axle. Lowering the vehicle basically raises the axle. To correct the drive line the front of the axle needs to be tilted down. The shim would be installed thick end forward. For vehicles with the leaf spring below the axle, the shim would be installed thick side to the rear.
