toytec coilovers left vs right

I remembering browsing around and seeing someone post that there is a difference between the left and right front coil over for this kit and I can't seem to find it. Can someone elaborate on this and give me the info? Also does it for the same on the rears for the Bilstein 5100 rear nitrogen gas shocks? Is there a specific left vs right shock?

And one other question. This kit comes with TT-RS - rear axle degree shims for proper pinion angle alignment (Not pictured...on the How-tow for installing an add-a-leaf, this part wasn't used? Is this necessary or just an added improvement? And where do I use this?

 

the fronts are different due to the added weight from you, gas tank, and battery. As far as telling them apart....im not sure. But the backs do not matter which side.

 

really..... hmmmm..... well i hope i have good luck haha

 

and by the way the shim goes on the bottom of the leaf pack against the axel

 

U may or may not need the shims - i started w/o them, then got vibe's. Installed the shims, and it cut down the vibes a little

 

fat side towards the rear of the truck

from google:

 

if this is the case would I have to adjust the left coilover a little higher then the right?

 

ahhhh gotcha.
