Bilstein 5100 help

I just had 5100's put on the front of my truck along with moog coils and noticed that the coil on the passenger side has a sticker that says drivers side. Do the coils really need to be on specific sides or am i okay? I am also putting 5100's in the rear next week and just noticed that one of the shocks is about a half inch shorter than the other. Is that normal and if so which side does the longer one go on. Judging by the coil installation i would like to give the guys in the shop some guidance. Thanks for your time

 

You probably should call the company but I'd say the coil should go on the drivers side. It may be a little stiffer or longer to compensate for the gas tank and the fact that the driver is usually the only one in the truck over time, in other words to compensate for sag.

The left side rear shock on a Gen. 1 Tacoma is shorter than the right side.

 

I phoned the company and they told me the springs are the same but couldnt tell me why one is labelled. Dunno?
