Pinion angle?

[99lt]

I have a 99 silverado ext. cab 2wd. I have a McGaughys 2/4 spindle shackle/ hanger drop kit that I bought used. I see in some other kits you need to add a pinion shim. Is that needed when I do my drop? I have 20's w/ 285/50/20 tires on the truck already if that matters. Thanks for the help, I want to get this installed asap but do not want to hurt something.

Did you ever complete the installation? I would like to know if there were clearance problems with the 285's.

thanks.

You adjust the pinion angle by installing a wedge (tapered) between the

spring and the axle spring pad. They come in a variety of angles.

I have the McGaughys drop kit on my SS.............spindles, shackles and hangers. I have had no problems with drive-line vibration so far, and my kit has been on for over a year. I know alot of people were having issues with vibrations and had to use a shim to correct it. I lucked out, and didn't have to go that route.
