Lift height

I have a 2011 Tacoma DCSB, TX pro, TRD with 285/75R16's, that I purchased used. It already had a lift on it, and I need to find out what size lift was put on. The rear shocks (bilsteins) need to be replaced and I want to make sure I get the right size replacement. I am not sure what the best way is to figure that out.......?

 

Take pictures
It would help us help you

 

Here is a couple of the truck itself, one of the front and one of the rear. The right rear shock is blown so it is not currently sitting level (right side is higher than the left side).

 

Looks like a toytec lift to me, which means max it's 3".

 

Ok, Thank you! I was thinking toytec and looked through their website, but wasn't sure and I am just learning about all this. Appreciate the help!

 

Yeah I was wondering if those were LRs but didn't want to give wrong info
