Recently leveled my RCSB 4x4 and thought I put up the link from another forum where a few pictures are posted.
Leveling kit glimpse - Tundra Solutions Forum

Leveling kit glimpse....continued - Tundra Solutions Forum
The installation was fairly straight forward and total cost was $130.00....oh, plus 80 more for the alignment. It rides the same but looks more likea 4 x 4 and I don't feel like I'm going to slide off the front seat now.

Nice pictures. Thanks for posting those. Did it take you a long time to do?

The leveling kit, the differential drop kit, etc. took a total of approx. 6 hrs. That was really taking my time and just enjoying the process. Could probably do it in 2 hrs. now.
